Whats the cat # on the bottom of the 2 phones. If the 4 button phone is a 73-100-1025 or 1026 (what dtmf said, volume buttons) </font>
Thanks for the prompt response. The cat number of my phone is 79-400-0000/B. A bit of history may be useful. We have two facilities that both have Telrad systems. These same type phones are used on both. According to the tech, the difference is the software program in the facility we are currently in is 4 years older than the version used in the other facility. When we moved, we brought our individual phones with us. The mute function worked perfectly in the other facility and I thought it initially worked here when we moved in but we were only here two weeks when we noticed it didn't. That was following a weekend storm that knocked all the phones out and they had to be reset. Even our 16 button phones with the talk back speaker phone capability will only mute the microphone when using the speaker phone option. When using the handset, the mute lights up but doesn't work. I don't know what software version is in use but again, the techs say that is the culprit.
