[Kamailio-Users] Engaging rtpproxy

[Graham Wooden]

Thanks Klaus. I will try the force_rtp_proxy() in the 302  
failure_route tonight; I already have the get_redirects and t_relay in  
there.

However, what is the best way to get in there for the 200 OK for the  
reply without having it be for evey call?

Thanks!
