Rob,
thanks so much for replying. Yeah, I forgot to add that I did check if codecs were in the system and the output of core show codecs is exactly like yours.

A few questions tho:
1. I have videosupport=yes in the general context of sip.conf is it where it's supposed to be? You are not talking about contextes of exntesions.conf, are you?
2. Are you certain I have to explicitly indicate codecs rules/priorities in each extension? I thought if they were in [general] that was enough.

thanks!
