I have a Polycom RealPresence 500 videoconference unit which is SIP capable.
I have successfully configured it to work with a 2Talk account, however the volume the recipient of calls from the Polycom unit hears is a bit low.
There does not appear to be any adjustment on the Polycom to adjust microphone levels for SIP, so I was wondering if it is possible to adjust the amplification level on a specific 2talk account, or is there some other way to achieve this?
