Hello, I am using asterisk for a conference system and am having issues with the volume levels of the different participants in the conference. Some callers will come in nice and clear while others will come across incredibly loud to the point where their voice gets muffled.
It seems that this is an issue with the phone the caller is using. If I have the loud person go and use the other phone they sound much better.
My question is what are my options on the asterisk end to combat this problem? It seems like a gain issue. I saw there is a configuration variable called rxgain for zapata.conf but does this apply to my IAX connection to VoicePulse? I only see mention of zapata hardware FXO interface cards…
Is there a way to put a hard limit volume coming into the machine? Are there codecs that are more controlled than what VoicePulse seems to prefer (ulaw?) Thank you for your help.
Asterisk 184.108.40.206 – VoicePulse Connect Service (IAX, ulaw codec) – Meetme Conference Rooms. I am not using the asterisk box as inbound/outbound phone system, it is only being used to host conference rooms.
