whe have a major problem, our polycom phones calls are always much louader then PSTN calls… whe dont want to add to mutch tx gain and whe would like to know if theres a way play with the polycom variable in sip.cfg to get PSTN and IP calls about the same volumes. thx
- doenst play with the audio on IP calls, ie by changing volume or doing echo cancel. You’d want to set txgain/rxgain on the analog channels so the resulting calls are on par with IP channels / analog phones…
anyone know exactly the difference between voice.gain.tx.digital and voice.gain.tx.analog?
