Well, actually the problem is that usually if someone uses the speakerphone to dial a call, a lot of times the number is dialed incorrectly. However, if we use the speakerphone again, mute the microphone, and then press "redial," the call goes through correctly. Only thing I can figure as that due to the handfull of noise that is in certain parts of our building, it causes a problem while dialing. I know on Toshiba phone systems, there is an option that you can program on a per-extension basis, that if a person hits "speaker" to use their phone, the microphone will turned off until they turn it on. Just curious if I had the same options.
