Dial plan contexts has nothing to do with how we set up RTP traffic.

If canreinvite=yes, we *will* issue a re-invite if possible.

Or h,H or nat=yes.

It is easier to turn it around:
Asterisk will issue a re-invite unless there is a reason
to keep the audio going through Asterisk

* NAT traversal issues
* Canreinvite=no
* Anything that needs asterisk to listen for DTMF in call
* Codecs that needs to be transcoded
