I have a Cisco SPA112 that is set up as an extension for a Polycom analogue conference room speaker phone. It works well… for a while. Sporadically, about 30 or 40 minutes into a call, the people on the other end of the call can’t hear us. The Polycom still things it is connected, but the audio is no longer heard.
How would I go about debugging this? Should I be searching for a specific error in the freepbx log file?
Thanks for your thoughts!!
