[asterisk-users] sipML5, Ast12 and WebRTC: not acceptable here

Fri, 14 Mar 2014 04:22:37 -0700 

Hi All.
I'm running some tests with the latest Asterisk SVN-branch-12-r410493M compiled with fresh github pjsip and srtp 1.4.2 on an i386 centOS machine (2.6.32-358.18.1.el6.i686). As a client I'm using the sipMLP WebRTC javascript softphone running on Chrome 33.0.1750.146 m. 


I have the softphone correctly registered on the Asterisk machine but as 
soon as I try to start a new call from the softphone, Asterisk answers 
with a 488 not acceptable here.



I'm probably missing something but I'm not able to find what and where. 
Is there someone able to point me to the right direction?

Below is my configuration. The sofpthone is registered as 1060.

Thanks in advance.
Marco Signorini.
