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 use
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 affect
other calls. At any given point of time, there might be more than 1 calls,
doing rtpproxy_destroy will stop rtp session for disconnecting call or can
it affect the existing active calls.
Thanks
Austin.
