1.3 Introducing The Impression
Model 2122X Monitor Telephone
The Impression Monitor Telephone has the same physical appearance
as the Impression Speakerphone. Although they look alike, there is one
functional difference in the way the telephones operate. The Monitor
Telephone includes a speaker that allows you to listen to incoming
calls. Although this model also features a microphone, you can only use
it to answer a call announce.
