Rusty Newton commented on ASTERISK-21246:
-----------------------------------------

Peter,

 The calls in the pcap don't seem to appear in codecchange.0 log file. The calls in the pcap have call-id  *3c2683f54ccd-awzivjl30opn* and *2eede5053b53a84e065150367d4ececa at 10.0.0.5:5060*. I don't see these in the log file.

> During call asterisk switches the negotiated codec (alaw) in the rtp to ulaw.
> If there is no renegotiation (like on my snom 720 sometimes), the user has a audible distortion.
