[Asterisk-Users] I Don't Want Asterisk in the Media Path

[Daryll Strauss]

Look for "canreinvite=yes" to get Asterisk out of the RTP path. Since
SIP traffic is infrequent and low volume having Asterisk in that loop
shouldn't be a problem, it's the RTP traffic you really want going
point to point. Realize that Asterisk can't get out of the loop if you
use the t or T option to support transfers or if you're recording the
call.
