Re: [SR-Users] Kamailio RTP Proxy Questions

Carsten Really appreciate your input. I am completely new to this. Please bear with me with easy questions. When you say I can use rtpproxy_manage() in the request and response and

rtpproxy_destroy() in BYE, I want to know where I have to modify. Is it kamailio.cfg file where I need to modify. If it is the case, do I need to modify the route block as below..., kindly guide me here with steps... # Main SIP request routing logic # - processing of any incoming SIP request starts with this route route { # per request initial checks route(REQINIT); # NAT detection route(NAT); ....................... Also, we are just telling rtpproxy_destroy in BYE case, will it not

other calls. At any given point of time, there might be more than 1

doing rtpproxy_destroy will stop rtp session for disconnecting call or

it affect the existing active calls. Thanks Austin. On Fri, Oct 7, 2011 at 5:39 PM, Carsten Bock <carsten(a)ng-voice.com>
