Mitel 3000 tech tips

When a voice mailbox is programmed for an extension, Forward On No Answer is automatically set to it. When the voice mailbox is removed through programming, the Forward On No Answer is automatically removed. However, if the extension has set Forward All Calls or Forward When Busy to the voice mail box, when it is removed then both of these forwarding options must be manually cancelled from the extension telephone. If they are not, the system will attempt to forward the calls to voice mail that is no longer there and gives the 'Invalid' indication and busy tone.

The normal operation is to forward group calls to the group voice mailbox. If this is done, then all calls both internal and external will be forwarded to the group mailbox. It is possible to forward calls to the system voice mailbox by using the code '0' when selecting the voice mailbox. However this mailbox is intended to act as an answering machine for incoming calls only and will not be activated for internal calls. If this is set for a group, then external calls will be forwarded to the voice mail but internal calls will not.

The recommendation is that group mailboxes are for calls to groups.

The system voice mailbox should be set if the customer wants an answering machine type service for incoming calls. The system voice mailbox is associated with the line(s) it is to operate on in “Lines Programming”. Once programmed, extension 20 can turn the system voice mailbox on and off as required. The system voice mailbox can also be set on permanently and a timer set in system programming. This timer determines how long calls ring on the line before the system voice mailbox answers the call.

When the Encore CX is powered up, it automatically detects the modules that are installed. The system then configures itself reflecting the modules installed and presents the system users with the correct menus for the number of lines and extensions installed. It also presents the voice mail menus if the voice mail module is installed.

If the voice mail is installed after the system has been powered up, it will not operate until the system is reset using the reset button in the MDF or the 'Reset option in system programming, or the system is powered down and up again.

When ringback is set to a busy extension, it operates immediately the called extension becomes free as long as the extension that set up the ringback is also free. If the extension that set up the ringback is busy, when the other extension becomes free, the operation is different.

In this case, the ringback is activated when the extension that has the ringback set to it becomes free and then goes off hook and on hook again. (The same operation when a ringback is set to an extension when it is ringing).

If more than eight digits are entered, the password is not changed and the original password is retained (1111 in default). Up to eight digits can be set as a voice mail password. Voice mail passwords can be checked in System Programming / Extensions / Examine Passwords.

An option is provided in the “System” drop down menu of the Maintenance and Programming Software application to allow the voice mail greetings and messages to be retained after a new system program has been flashed to the system.

The procedure for flashing a new operating system program to the Encore CX is as follows:

1. Connect to the switch with the Maintenance and Programming Software application either locally (on site) via the serial interface or remotely.

2. Retrieve the full database of the switch and store it in an appropriately named file.

3. Retrieve the Voice Mail file using the VM Backup \ Restore Manager in the System drop down menu. (When thisdata is being retrieved, the voice mail ports on the switch are temporarily disabled to prohibit changes to the voice mail until the file is restored).

4. Send the new system software to the switch. When the file is sent, the system will automatically reset and the connection to the switch will be broken.

5. Do not reconnect to the switch for some 90 seconds to allow both the switch and the voice mail to reset correctly.

6. The switch will start running approximately 30 seconds before the voice mail, and if you reconnect in this period and re-send a database or the voice mail file, the voice mail will not be correctly programmed and some messages will be lost.

The data port is primarily intended for PC modems rather than standard telephones. Caller ID information is supplied to ECX 1000 and ECX 2000 phones as a digital signal on the cd pair. This means that the Caller ID information is not supplied on the a, b, pair, so it is not available to any device connected to the data port on the ECX phones.

The default setting on the Encore CX is that the extension numbers are two digits long. If a system is reprogrammed with a three or four digit numbering scheme, it must be reset to its default values to get back to a two digit numbering plan. It is possible to go between three and four digit numbering by reprogramming rather than defaulting.

If the numbering plan is being changed in the flexible numbering programming, it is essential that this is the first programming to be carried out as it affects many of the other programming options.

Calls to groups are forwarded only if the Group Forwarding facility is programmed. If group calls are to be forwarded to a mail box they can only be forwarded to the Group Mailbox.

Individual extensions can forward their phone to their own voice box. However only calls for the extension (not calls to the group that may be ringing the phone) will be forwarded to the extension's voice box. These calls are internal calls to the extension, dialed using the extension number (not the group number), incoming calls to the extension routed using Caller ID, or lines programmed to ring the extension only.

If a caller hangs up when listening to the auto attendant greeting or before the call is answered by an extension, then, if the lines are not 'supervised' (a disconnect signal is not supplied to the Encore CX), the call will continue to ring and when answered there will be no one on the line.

The solution to the problem is to have the line type changed (by telco) so that a disconnect signal is supplied when the caller hangs up. The Encore CX will detect the signal and disconnect immediately. The Telco Provider can change the line type to provide the disconnect signal when the caller hangs up.

The following digit(s) can be dialed during the auto attendant greeting:

Nothing. This rings the default group (group 1)

Invalid. This rings the default group (group 1)

Single digits

 0 This rings the default group (group 1)

 1 This rings Group 20

 2 This rings Group 19

 3 This rings Group 18

 4 This rings Group 17

 5 This rings Group 16

 6 This rings Group 15

 7 This rings Group 14

 8 This rings Group 13

 9 This rings Group 12

 * This allows you to retrieve Voice Mail

 # This plays the Directory greeting (if one is recorded)

Two digits (the second digit must be dialed within 2 seconds of the first digit)

 20 This rings extension 20

 21 This rings extension 21 ..to..

 40 This rings extension 40

Three digits (the second digit must be dialed within 2 seconds of the first digit)

 100 This rings phantom mailbox 100 (if programmed)

 101 This rings phantom mailbox 101 (if programmed) ..to..

 109 This rings phantom mailbox 109 (if programmed)

 180 This rings Group 1 (ring or hunt group)

 181 This rings Group 2 (ring or hunt group) ..to..

 199 This rings Group 20 (ring or hunt group)

Note: If flexible numbering has been programmed then some of these codes will have changed.

The CX Maintenance and Programming Software is designed to ensure that when extension and facility numbers are being changed, the switch is not programmed with conflicting numbers.

1). If you change the "First Extension Number" to start with a digit that is already used to operate a facility, then the facility code is automatically changed to an unused number.

2). If you try to program two extensions or facilities with the same number, the conflict is highlighted with a green background. If you arrive at a situation where it is becoming difficult to resolve all the conflicts use the Reset Current Pane to Default" button and start again.

While the Encore CX does not support Auto-attendant directory trees directly, this functionality is possible indirectly because it has 40 extensions, 20 groups and 10 phantom mailboxes, all of which will allow you to dial through their greetings to any extension. An example of this functionality is as follows: Auto-attendant greeting:

Please dial 100 for sales, 101 for marketing, 102 for operations, 103 for hardware, 104 for software, 105 for IT or wait or dial 0 for the operator".

Dialing 100 would get you the "Sales" Phantom mailbox greeting 100 as follows: "This is Sales, please dial 20 for Matthew, 21 for Mark, 22 for Luke, 23 for John, 0 for the operator or please wait to leave a message for the sales department." Dialing 23 will then cause John's phone to ring. A disadvantage of this method is that they will have to regularly check the phantom mailboxes for messages as no visual indication, is given to the ECX phones, when a phantom mailbox has a new message.

Unused groups could have been used instead of phantom mailboxes for the functionality above, with the added advantage that any ECX extensions in the group will get a visual indication on their phones, when there is a voice mail recorded.

To answer a call using the 'Call Pickup' facility, the extension must in the same group as the ringing extension

The 'Call Pickup' facility allows extensions within the same group to answer each others calls. All calls to the extension, internal and external, are answered using this facility.

Separate pick up group programming is not provided. However, up to 20 groups can be programmed in the system, so, some of these groups are used to program the extensions that are to answer each others calls using the Call Pickup facility.

Program the extensions that are to answer each other's calls using the 'Call Pick up' facility into groups. Up to 16 extensions can be entered into each group.

The Encore CX can work with two types of paging amplifiers on a station port; those designed to work on telephone systems, and those which only offer a microphone input.

If the PA Amplifier is one designed to work on telephone systems, then one of the telephone extension ports, (with the exception of the programming extension 20), can be programmed as the paging port and directly connected to the PA amplifier. On the amplifier, typically the input is marked "telephone" and has the internal 600 ohm transformer isolated input built in. It is recommended to check the amplifier's specifications.

If the paging amplifier is the type that provides a microphone input , a 1:1 Audio Isolation transformer with a 600-900 ohm impedance, must be connected between the extension port and the microphone input. A Radio Shack 1:1 Audio Isolation Transformer (p/n 273-1374 ) was used by Intertel to verify this operation, but any transformer with a similar specification will work. Also, commercial 1:1 (600 - 600 ohm) transformers are available from most sound system suppliers.

There is an option to turn on a background noise monitor in the ECX 1000, ECX1000W and ECX 2000 phones which will improve their speaker phone performance when the phones are located in a noisy area. The option is in the the phone setup menu, and each phone can turn the feature on and off.

To select the option:

Press the "PROGRAM" key on the phone

Scroll down the menu and select "Speaker Phone Options"

Select the option "Noisy Environment On" to turn the background noise monitor on.

The default setting is that the feature is Off.

The nine is inserted by the Encore CX so that calls can be made directly from the Caller ID store in the phones.The Caller ID information for internal and external calls is supplied to the phone. The nine is inserted when the number is received from an external call. The nine is not stored when the call is received from an internal call. Using the nine allows both internal and external calls to be redialed from within the phones. Caller ID store with nine is used to identify external numbers.

The maximum number of extensions that can be included in a group in the Encore CX is 16. Up to 20 Groups can be programmed and each can have up to sixteen extensions. The groups can be programmed as Internal Groups,Ringing Groups (For CO Lines) or Hunt Groups. In default, Group 1 is programmed with the first eight extensions and the remaining 19 groups have extension 20 only in them.

Yes. When a caller dials 0 in the auto attendant the call is routed to the group that is programmed to ring for the line the call is received on. This group can be programmed with up to 16 extensions. These options are selected in the Incoming Ringing Option in Line programming and in Group programming which is also in the Line programming menu.

During the Beta trial of he Encore CX, it was found that a number of sites had modems connected to the lines and they were answering calls before the calls were answered by the Encore CX system. It is important to check, particularly on small office or domestic sites that did not have a system installed, that all Fax machines, modems, etc. are connected to extension ports in the Encore CX.

The Encore CX system software version and the system hardware configuration can be viewed from the Management and Programming application under the "Diagnostics" drop down option on the menu bar. It is viewed in the "View CPE Configuration" option.

The system version can also be viewed in phone programming (Ext 20 by default) Programming - System - Reset Options - Version Info.

The time on the EncoreCX must be corrected after a reset or software upgrade. The time is reset to a default setting if the switch is reset to default. The clock also loses some time during a power/switch reset. If there is Caller ID on the lines the time is corrected on the first incoming call after a reset so in this case the time is corrected automatically.

However if there is no Caller ID on the CO lines the time must be reset from the programming phone or the Management and Programming application, MPS.

It should be noted that the time is updated immediately if there is no outgoing CO Line call in progress. However in order to ensure the duration of any originating calls in progress is correctly logged in the SMDR log the update of the time is held off until there is no originating call in progress.

Calls through the Auto Attendant to busy extensions are presented to the default ring group for the line the call is received on. If this group is busy then the calls will camp on for a period and if not answered will be disconnected. It is recommended that when programming the system the groups should have forwarding on Busy programmed to a Voice Mailbox to ensure the caller is dealt with successfully.

During the recording of a voice message in a voice mail box, the user can re-record the message without having to hang up and dial in again by pressing any of the digits 0 - 9. This will stop recording, delete the message up to that point and replay the mailbox greeting allowing the caller to record a corrected message.

Call into the system and when the answering machine answers, dial "88". When it asks for an extension, dial 0 for the answering machine, not 20.

The data port provides the location for the connection of devices such as PC modems, cordless telephones, additional ringers/ringer lights or Recording equipment (recording equipment needs to be ac coupled). It is important not to go off hook on a cordless telephone or modem when on a call on the feature phone as you will hear 'dead air' on the feature phone, which might be mistaken for a loss of transmission. Equally do not try to operate the feature phone when the data port (analog phone or modem) is off-hook. Also note that if you are swapping between an EXC and cordless telephone you should go off hook on the cordless telephone before hanging up on the ECX if you want to maintain the call in progress.

Note: If your modem is configured in auto-answer mode (for example because the connected PC is running a fax or answering machine application), then incoming calls may be answered unexpectedly by the modem.

The EncoreCX Internet Module is specifically designed as an Internet Sharing device for small businesses. It is not designed to provide the Branch Office or VPN access. It does not support VPN Passthrough. It is designed purely to enable web access to multiple client PCs. VPN Passthrough is typically used for Branch Office Remote Access, which is not supported.

The trace option activated in Encore programming may slow the system down causing the time to drift. On the programming station (ext. 20 by default) go into system programming Scroll down and select the key below 'cancel' (it is blank)

Select 'Debug option'

Scroll down to 'debug 8' turn to OFF.

A basic directory service is provided and available for use within the system. This is programmed within the Auto-Attendant area of the system and allows the user to record a list of extensions [and/or groups] which may be dialed from within the Auto-Attendant. In the simplest format, the directory greeting may be recorded to list all extension and group names and numbers in alphabetical or numeric order, and this solution is suitable for small sites. In this instance the incoming caller will be answered by the Auto-Attendant; they are then invited to press # for a company directory listing. The directory greeting will then list all extensions, for example:

The call initially answered by Auto Attendant says, "Welcome to Acme Products Inc., if you know the extension of the party you wish to reach you may dial it at any time. You may also dial # for a company directory or connect directly with the following company departments:

for Sales, dial 1,

for Service, dial 2,

The following system feature is supported in the EncoreCX but is only partially documented in the Owner’s Guide.

Providing a Basic Directory Service

A basic Directory Service is provided and available for use within the system. This is programmed within the Auto-Attendant area of the system and allows the user to Record a list of Extensions [and/or Groups] which may be dialed from within the Auto-Attendant. In the simplest format, the Directory Greeting may be Recorded to list all Extension & Group Names and Numbers in Alphabetical or Numeric order, and this solution is suitable for smaller sites. In this instance the incoming Caller will be Answered by the Auto-Attendant, they are then invited to press # for a Company Directory List. The Directory Greeting will then list all extensions, for example:

Providing a Structured Directory Service

It is also possible provide a more structured Directory Service by utilising the Auto-Attendant combined with Groups or Phantom Voice Mail boxes to provide a more detailed breakdown of the Company Directory. The primary advantage of this set-up is to provide the Caller with shorter lists of Extension Names and Numbers on systems with larger numbers of extensions configured.

Please Note

• If using Groups, the Groups used are not available for other functions and the Group must be set to Forward All to the Group Voice Mail Box.

• If using Phantom Voice Mail Boxes, it is necessary to have a 3 digit dial through code.

• It should be noted that using the options described below, it is possible for calls to be terminated into a Group or Phantom Voice Mail Box if the Caller does not follow the instructed actions. With this in mind it is advised that:

• The Recorded Prompts advise the caller not to leave a message.

• The Mail Boxes used are checked by company personnel from time to time.

If the caller does not make a selection before the Tone they will be in the VM record phase. Dialing any digit at this point will replay the message. The caller could leave a message at this point (although they have not been invited to do so). If the caller leaves a Message it will be stored in the relevant Phantom VM Box.

Notes

• The Basic Directory service outlined above is fully operational and defined in the Owner’s Guide.

• The Basic Directory service is simplest to program and only involves recording a Greeting in one area.

• The Structured Directory service requires a reasonable level of programming and significant recording of Prompts within the system (as does any full Directory Service or Dial by Name Application)

• The Structured Directory Service may utilize either:

• Group Voice Mail boxes with single digit access (1..9), however these Groups must be manually forwarded to Voice Mail, and may not be utilized for other Group functions

• Phantom Voice Mail boxes with three digit dial through (101..109), these Phantom Extensions are preconfigured as Forwarded to Voice Mail, and use of these will leave full Group functionality available within the system

• The example shown above shows the Directory Structure broken into 6 groups, any alternative logic may be followed as required. For example, it may be preferred to utilize the layout of the telephone keypad so that

Using Phantom Using Group For Names beginning

Dial…… Dial…… with letter…..

102 2 = abc

103 3 = def

104 4 = ghi

105 5 = jkl

106 6 = mno

107 7 = pqrs

108 8 = tuv

109 9 = xyz

• The maximum recording length for the Greeting in the Auto-Attendant, Directory Message, and Extension, Group and Phantom Voice Mail Boxes is 180 seconds, the Greetings must be planned to fit in these times.

• It should be expected that full utilization of the above messaging will utilize in the region of 1 hour of system voice mail resources. With this in mind Dealers should be advised to supply larger capacity Voice Mail units when providing significant Directory Service or Complex Auto Attendant features.

User Timers - external timer default is set for 5 minutes and can be set from 1 to 30 minutes. If a call comes in to an extension and it is forwarded to an outside trunk and all trunks are busy, the system will send the call to extension 20. If you make an internal transfer to a trunk and all trunks are busy, you will also get a busy signal.

The phone programming settings are not updated when a database is restored.

This includes:-

- Auto Answer

- Headset mode

- Background music

- Ringing Options

- Contrast Options

The Time and date is not restored. This needs to be set separately when a database is restored as the recovered time will not be correct by the time it is resent.

The EncoreCX provides a message-waiting signal to standard telephones using the CID protocol. The ECX 100 phone recognizes the signal and an envelope symbol along with the text “Message Waiting” is shown on the display. The CID signal is preceded by a reversal to put the phone into “listening” mode so that it correctly detects the signal.

On some older phones, with electromechanical ringers, the bell will “tinkle” when a reversal is sent. So if an extension is programmed with a voicemail box, or is in a group that has a group box, and it is connected to an older phone with an electromechanical bell, it may tinkle when the signal to turn the 'message waiting' indication on or off is sent to it. The message is sent when a new message is left in a box. It is also sent when the indication is being turned off. The signal is also sent some seconds after the handset is replaced on every call. This is to ensure that the message indicator on CID phones is in sync with the voice mail box. So the bell may tinkle about 5 seconds after the user replaces the handset.

It is possible to link two Encore CX systems together by connecting extensions from one system to CO Line interfaces on the other. Two different options can be configured giving different levels of operation.

Configuration 1.

Two systems, system A and system B. If some extensions from system A are connected to CO line interfaces on system B it is possible to make calls from one system to the other. An extension on system B can call an extension on system A by selecting one of the lines connected to an extension on system A, and dialing the extension number. The lines connected to the extensions on system a should be programmed into a line group. If the lines are programmed into the group accessed by dialing 760 then extensions on system A can be called by dialling 760 and the extension number.

Extensions on system A cannot call directly to extensions on system B. They can make a call to the extensions on their switch which are connected to the CO lines on system B and they will be presented as an incoming call on system B.The calls can be answered and transferred to the relevant extension. Alternatively they can be answered by the auto attendant and then they can dial through to an extension.

Configuration 2.

Two systems, system A and system B. This configuration is symmetrical in that extensions from system A are connected to lines on system B and extensions on system B are connected to lines on system A. Both systems can now contact extensions in the other switch by selecting one of the interconnected lines and dialing an extension number. The lines in each switch should be programmed into a separate group from the normal CO lines.

If call comes in from auto attendant and caller dials a extension that is in DND, the call will be routed to extensions that are programmed to ring in the day group.

If call comes in from auto attendant while system is in night mode and caller dials a ext that is in DND, the call will be routed to extensions that are programmed to ring in the night group.

If the call comes from a internal party, they will get a busy signal

The paging amplifier must be the type that supplies "talk battery". Typically, this is 24 volts DC applied to tip and ring connection. They amplifier usually does not provide dial tone (exception is some zone units) so if it doesn't, disable dial tone detect on that line (Line Programming/PSTN/Dial tone detect)

In release 1.1 of the system software it is important that the 'Last Digit Delay' timer is NOT set at 5 seconds. This can occur if a database from an earlier version of software is retrieved and sent to a switch running version 1.1 software. It is important that this timer is checked after the database is restored. The timer is set through the Maintenance and Programming software. It is in the Diagnostics / Technical Timers page and is the fifth entry from the bottom of the table. The recommendation is that this timer is set at 3 seconds.

The feature called 'CO Hunting' is done by the Telco Central Office (you must order this for the lines from the carrier).

They also sell a tester for $35 that every telephone system tech should have. You can test line loop current in series with a multimeter, but it is a pain holding the connections in place (and you have to have a call in progress as you test). The tester makes it much easier - just push a button.

Auto-attendant transfer to busy extension having fwd no answer to VM rings 20

As designed:

If the extension is busy, the call is presented to the default Ring Group for the CO line the call is ringing on. (in this case default is extension 20 in ring group 1)

As Designed. This shows that handsfree intercom answer is enabled.

Opening the door fails because the "Open the Door" key is pressed for more than 2 seconds

This is most likely because the key is pressed for greater than 2 seconds. This timer applies to all keys on the system phones and if the key is pressed for too long a period, it is ignored. In the case of "Opening the Door" Some people are used to pressing door opening keys for the duration they expect the door to stay open and are inclined to press the key for too long a time.

This is usually caused when the caller has hung up and the phone(s) continue to ring for a period. If the ringing phones are answered during this period it will appear to be a "Phantom call" - no one is on the line.

The ringing signal on the Telco line is ringing on for 1 second, off for 4 seconds, repeated. When a caller hangs up the line stops sending the ringing signal. However the system will not be aware that the ringing has stopped for some seconds. The system will stop ringing the internal extensions when it has not detected a ringing signal on the line for a period 5.5 seconds. The internal phones will still indicate there is a call ringing within this interval. This period will be variable but can be up to the 5.5 seconds. If a phone is answered in this period there will be no one on the line as this is a function of the ringing signal detection timing, there is nothing that can be done other than make the user aware of the issue.

If the call is on a line which is programmed for Auto Attendant or Courtesy Service, it is essential that the Telco line have calling party supervision provided by the Telco. This provides a disconnect signal when the outside caller goes on hook When a call is received by the system, the Auto Attendant or Courtesy service will answer the call and ring the appropriate extension(s). If the external caller hangs up before an extension answers the call, the line will send a disconnect signal to the system. The system detects this signal and stops ringing the extensions.

If the Telco line is not supervised, the caller can go on hook but as no indication is given to the switch that the caller has gone, the switch will continue to ring the internal extensions until the ring detection timer times out on no repeated ring from the Telco. When this call is answered there will be no one there.

It is important to check with the Telco that Calling Party Disconnect supervision be provided on the lines connected to the system.

If Caller ID is not provided on the lines and the system is programmed to expect Caller ID, there will be a delay between calls being presented to the system and the extensions ringing. This is caused by the system trying to detect the Caller ID signal after the first ring burst. It delays a period of several seconds trying to detect the Caller ID signal before it rings the extensions. This delay can be eliminated by reprogramming the lines not to detect caller ID.

If Caller ID is presented on the line, there is a delay as the system detects the Caller ID information after the first ringing burst and transmits it to the extensions. The extensions are rung when the Caller ID information has been decoded and the information can be presented to the extensions. This can cause a delay of some seconds before the extensions are rung.

This is because the line or lines are incorrectly programmed as "Loop Calling" lines. Go into programming lines and turn the loop calling off for all lines.

Loop calling should only be used for a ring down circuit / tie line.

If a call is made by dialing 9 and continuing to dial the phone number without waiting for the CO dial tone, there will be a delay in switching through the speech path after the call is dialed. This is because the system stores the digits and then resends them once Telco dial tone is detected. However, the system does not know when the last digit is dialed so it switches the speech path through if it has not detected a dialed digit for about 4 seconds.

If this is causing a problem, users should wait after dialing 9, and then continue dialing the number when they hear the Telco dial tone.

This delay will always be present if they use "redial" on standard phones.
