comedia RTP handling.
Note:
"comedia RTP handling" refers to the technique of sending RTP to the
port where the other endpoint's RTP packets come from. This can also
be rephrased as "connection-oriented media".
If enabled, the UCM6100 will try to redirect the RTP media stream
(audio) to go directly from the caller to the callee. The default setting is
"No NAT".
Yes

No NAT: Allow media path redirection (Reinvite) but only when the

behind NAT or not based on the IP address where the media comes
from.
Update: Use UPDATE for media path redirection, instead of INVITE.

Note:
Some devices do not support this (especially if one of them is behind
NAT).
