Hello Christoph, I don't know if you found a fix to this issue. I just had the same on ubuntu (with the same asterisk release)... It seems the components are trying to renegotiate the codecs, I had no time to test it further but removing any disallow=... and allow=... in my iax.conf did the job. Hope this help, Cheers.
