Hi all, we do have the following configuration (non-Asterisk PBX) - T1 - ZAP (Asterisk PBX) - ZAP - T1 - (GSM Gateway) -> GSM Enduser The call is originated on the (non-Asterisk PBX) - gets send over a T1 connection to the asterisk server (which does least cost routing) - the asterisk server then does send the call over a GSM Gateway into the world... The Problem we do have is - that the Users behind the non-Asterisk PBX are complaining about low volume media if the the calling through the gateway (if the are calling mobiles...). So i have started to raise the rxgain value for the connection between the asterisk box and the GSM Gateway, this does work quite well - but not really perfect. The ringback (not locally generated - does come from the GSM Provider) does get terrible loud - as soon as the callee is connected - the speech is nearly not hearable because it has such a low volume. The ringback is EARLY MEDIA - if i am right - and the speech is normal MEDIA. So, is it possible to set different gains for EARLY MEDIA and normal MEDIA ? Does anyone else have had this problem ? regards, Wolfgang
I've been fighting with this issue for over a year. There are several threads here talking about it: Digium Zaptel volume issues setting of volume Low volume/audio problems on TDM400 card increase the volume ? There is one thread (Voicemail volume adjustment) that give me hope that this can be fixed that mentions adding |usg(10) to the dial command to increase the gain. I'm still a novice at the inner workings of asterisk so I'm hoping one of the gurus on the list will figure this out eventually.
