<br>
Are you sure you are getting Astrisk out of the media path? I guess<br>
reinvite must be allowed. Then it should work without transcoding<br>
licenses.<br>
<br>
Maybe you should take a look at the SIP DEBUG info to see what codec<br>
Asterisk is trying to negotiate with the trunk. You could disallow<br>
alaw and ulaw for a test.<br>
