> I have an environment which uses an Asterisk 15.3.0 to bridge calls to WebRTC endpoints configured using OPUS codec. The calls are originated on another Asterisk, connected to this using ALAW codec.
> All the calls run the same dialplan (that simply calls the webrtc client) and the same webrtc endpoints, but randomly the following errors shows on the Asterisk console, and I get no audio on the calls.
