Uplink(g729,alaw)<-asterisk->Yate(g729,alaw)<->client A, Client B
Both clients are g729 and alaw-capable, I’ve checked settings on both devices.
Client A can call to PSTN only if I change uplink codec setting to “alaw,g729”, Client B can call only if I revert these settings back to “g729,alaw”. In opposite case, I have one-directional voice and transcoding don’t mitigate the problem.
Is it possible to permit caller and called to negotiate codecs by themselves without Asterisk interference, like Yate does?
I want Asterisk just sends in OK/SDP to caller only codec that is proposed by called, NOT full called codec list from sip.conf.
