[Asterisk-video] AMR passthrough patch on bugtracker

[Klaus Darilion]

Hi Koen!

Have you activated AMR in sip.conf?

disallow=all ; or something similar ....
allow=all


When does this error happen? Is there an INVITE sent to xlite or does 
the error happen before?

can you post the INVITE received by Asterisk?

regards
klaus
