I got one way audio on chan_mobile last few days. I see in my 701 ext setting that i changed allowed codec to "g722&uLaw&aLaw&h264&g729&gsm".
When I changed this only uLaw or g722 I get audio on both side. I do not understand what is the problem?
I install Incredible pbx 13.13.7 ubuntu 18.04, Asterisk 13.25.

Probably that you have G.729 - a low bandwidth codec with compression, and many carriers like this because it doesn't use as much bandwidth. Unless you purchased a G.729 license, you don't have one and your server won't know how to communicate with the other side. If you have sufficient bandwidth - then force them into the Ulaw and you won't have codec issues.

H.264 is a video codec and I doubt that will work with chan_mobile. If you are running video through Asterisk, there are other settings that must be added to the system and I don't think you can use video with this channel driver. The @krzykat suggestion that you might need to purchase a g.729 license may be your issue.

I have to sepatate extention for chan_mobile. If i put video and audio codec in extention one way audio exists. But when i use only single codec problem was gone. May be this is the problem of chan_mobile. Call from other trunks are fine, no need to use single codec in extention.
