[RTPproxy Users] RTPproxy is not running

[Maxim Sobolev]

Khan,

Most likely there is some logical mistake in your routing script. The 
'0' reply from RTPproxy means that there is no such session in there. 
Possible cause of this is not invoking force_rtp_proxy on INVITE, I can 
only see 200 OK and 183 Session Progress in your log.
