I have an intermittent issue with VVX 500 and VVX 600. So intermittently the phone has no audible inbound ringing but the LCD screen does show the incoming call and I am able to answer. Has anyone experienced this issue. I am running a Asteisk 1.8 server phone firmware is 5.2.0
welcome back to the Polycom Community.
Are these phones by any chance part of a Busy Lamp Field or similar ? Are you using special Ring Tones or SIP Headers ?
I suggest you replicate the issue and then check the log for the occurrence of :
0122121135|so |4|7475|soTonePlay: pcmChannelP is NULL
If the above appears it may be similar or the same as we currently have an internal case for. If this is the case please raise a Service Ticket via your Polycom reseller and quote VESC-4973 as you then may be able to get a Hotfix for this.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

I'm getting this error on 5 of my Polycom 550 phones and I was wondering if you could post that hotfix you were talking about or if you knew what is causing this error.
The phones don't make any noise when ringing but I can see the call coming in.
