I have problems with sems and SER+mediaproxy
When i send a call to sems for voicemail the SDP content received by sems have the c= line
with the private address of caller. Before send the call to sems my SER use mediaproxy to
fix nat problems, but sems dont receive the SDP changed and the RTP generated by SEMS is
sent to the wrong ip address.
-- on my ser.cfg --
if (method=="INVITE") {
log(1,"ROUTE_0: INVITE METHOD\n");
if (!search("^Record-Route:")) {
log(1,"ROUTE_0: Use Mediaproxy");
use_media_proxy();
};
...
log(1,"ROUTE_1: ARCOTEL-TO-ARCOTEL ");
lookup("aliases");
if (!lookup("location")) {
log(1, "ROUTE_1: USER OFFLINE OR INVALID\n");
route(8);
break;
};
...
route[8] {
log(1,"ROUTE_8: VOICEMAIL");
if (!t_newtran()) { sl_reply_error(); break; };
use_media_proxy();
t_reply("183","Conectandose");
if(!vm("/tmp/am_fifo","voicemail")){
log(1,"could not contact voicemail\n");
t_reply("500","could not contact voicemail");
};
break;
}
