Wireless Headset Problems with Plantronics APC-4 HHC adapter
Appreciate if anyone has any permanent solution for this. We have a deployment of 7965G and 7975G IP phones along with a number of Plantronics CS-50 & CS-55 headsets. We're using the Plantronics APC-4 Headset Hookswitch Control (HHC) adapter so we don't need handset lifters.
Every once in a while (usually after an event, like a phone reset, but not necessarily) the headset, the HHC adapter, and the phone get "out of sync". In this state, 3 things happen:
1) Pressing the button on the headset picks up the headset base but doesn't pick up the phone
2) The ringer does not beep in the headset when the phone rings
3) If you answer a call by pressing the headset button on the phone, and then activate the headset by pressing the button on the headset, you can talk and hear for about 10 - 15 seconds, at which point the headset turns off but the call does not drop. You can pick the call back up from the headset or the handset.
It looks like no signalling information is passing between the headset and the telephone.
The current resolution is to completely disconnect the headset and adapter from the phone and power, reset the phone, the reconnect the headset and adapter. This usually gets things back in sync, but sometimes takes a couple of tries. I've tried with phone firmware from 8.3.4 to 8.4.4 with the same results.
Does anyone else have this problem? If you've identified a permanent solution I'd love to hear it. Plantronics doesn't have one, I've called them too.
Re: Wireless Headset Problems with Plantronics APC-4 HHC adapter
The current "solution" that I've been using is to disconnect the headset base completely from the phone and power, reset the phone, then reconnect the headset base to the power and the phone. This usually works. Sometimes I have to do it a couple of times.
Once in a while just power cycling the headset base will work.
