[SR-Users] Issue handling SRTP and RTP with rtpproxy and rtpengine

[Alberto Sagredo]

Roberto just call it on NATMANAGE as shown. I route everything now thru
that route..

You have to configure rtpengine to use internal external interfaces

route[NATMANAGE] {


#!ifdef WITH_NAT


# if (is_request()) {

# if(has_totag()) {

#  if(check_route_param("nat=yes")) {

#  setbflag(FLB_NATB);

#  }

# }

# }

# if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))){

# return;

# }

# route(RTPPROXY);


route(RTPPROXY);


 if (is_request()) {

 if (!has_totag()) {

 add_rr_param(";nat=yes");

 }

}

if (is_reply()) {

 if(isbflagset(FLB_NATB)) {

 fix_nated_contact();

 }

}

#!endif

return;

}
