Rest in Peace, after a 10-year run.
It's been Bell 412CID, IBM 412CID,
and PhoneMate PMG4125.
Now it's the Cortelco 4125.
4-Line phone with intercom & Caller ID.
Use up to 12 phones together.

This is the phone that refused to die, but as of 5/1/08, it's finally dead.

It's been sold as the Bell Sonecor 412CID, the IBM 412CID, and the PhoneMate PMG4125. And for the last few years it was sold by Cortelco, the company that used be known as ITT; and it's compatible with all the other versions.
