Title: GSM/MULAW Audio Codec Problem?
Post by: zane93 on September 04, 2014, 11:39:19 AM

I'm not quite sure where to start as I'm a new to yate and yatebts... So I can make a call and keep the call up for an extend period without issues but I get no audio. Here is the errors that I'm getting once the call is answered. This also happens when calling 32843 David. SMS is working fine.

The module gsmcodec.yate is missing.
If you built yate from sources you need libgsm devel.

I installed libgsm1 and libgsm1-dev re-pulled from the trunk and built again. Now everything is working as expected. Thank you for the help!
