Why has my Synergy 2150 phone stopped working?
The handset on my Synergy 2150 phone is about 4 years old - about 1 yr ago, I noticed that, although I could hear callers when they rang me, my phone did not transmit my speach (or any audible sound). Conclusion: handset microphone has ceased to be functional!
