Look like on the other side used Asterisk. In such a case, I offer only one codec and from another side, I receive a response with only one code. Sergey On Sun, Sep 26, 2021 at 11:40 PM Allan Kristensen <ak@hejdu.dk> wrote:
Hello,
We are getting these weird log messages from FS and I'm a little uncertain what they are (there are thousands being logged), can someone clarify?

I'm thinking it's because we are receiving RTP packets with both types from remote?
It only happens for a specific provider, so I'm thinking it's them, I just need to tell them the problem is. During codec negotiations we offered PCMA + PCMU and the SDP response from them also had PCMA + PCMU, that means we can choose what we want right? not that they should send us both? ;-)
