On the callmanager you can only really turn it on or off. To my knowledge you cannot change the threshold. On the router you can change the music threshold. In callmanager it is called silencesuppression.
When I was calling from an IP Phone through PSTN, when nobody was talking, there was no noise, there was a blank, as if the call was dropped. To change that, I didn't change the thresholds, I only wrote this command on dial-peer serving your CallManager (your voip dial-peer):
It desactivates the voice activation detection then the comfort noise feature is not used anymore to save bandwidth.
Currently, I'm also experiencing the same problem that you mentioned. My problem is that whenever I'm calling from the IP Phone through the PSTN, I always heard a hissing sound whenever the other party stop talking. I have disable VAD on my voip dial peer and also disable VAD on Cisco CallManager. But the problem is still persistent. I have even tried adjusting the value of input gain and output attenuation on the voice port. Still, it didn't work.
I only notice that on outgoing call. But for incoming, I don't have a problem. Do have any other idea aside from deactiving VAD?
yout problem is the backward dial-peer. If you call from an IP phone in the PSTN direction first the pots dial-peer will be matched. In the CallManager direction the "default dial-peer 0 " will be taken. the default dial-peer has always vad enabled.
You can solve this with " incoming called-number .." command on the voip dial-peer.
I'll try the tip that you gave me. Although , it never come up in my mind that "default dial-peer 0 will be taken since this is an outgoing call. This will be first time that I will be using incoming called-number on the voip dial-peer. Usually, I use destination-pattern.
