I’m experimenting low audio in the incoming calls over an IAX2 trunk. In intranet SIP calls, incoming calls over a SIP Trunk, and outbound calls over the same IAX2 Trunk the audio is clear in both directions. However, in the incoming calls the audio is low. We’ve tried different handsets, and the issue keeps on happening. Is there a way it can be increased? Please find below the contents of the iax.conf file (user, password and host have been ommited for security purposes).
Thanks in advance
