I have OpenSER installed on a system with 4 network interfaces. When OpenSER sends out an INVITE to an Asterisk system, it puts the Record-Route header in the SIP message: U 216.186.140.205:5060 -> 172.31.140.203:5060 INVITE sip:9220402@pbx1-mgt0.ipt.oneeighty.com:5060;user=phone SIP/2.0. Record-Route: <sip:216.186.140.205;ftag=C0A1B748-F1234161;lr=on>. However, I would like it to put a different IP address in the Record-Route header, to force the Asterisk system at the other end to send replies back on a certain interface. I tried using record_route_preset instead of record_route, like this: record_route_preset("172.31.140.205"); Now, when SIP messages go out, they look like this: U 216.187.140.205:5060 -> 172.31.140.203:5060 INVITE sip:9220402@pbx1-mgt0.ipt.oneeighty.com:5060;user=phone SIP/2.0. Record-Route: <sip:9220402@sip:172.31.140.205:5060;ftag=D26AD271-F90F8EC6;lr=on>. Huh? Why has OpenSER put the to URI in the record route? That doesn't look right to me. I also tried using record_route_preset like this: record_route_preset("172.31.140.205:5060"); record_route_preset("sip:172.31.140.205"); record_route_preset("sip:172.31.140.205:5060"); and it always puts the to uri in there. Why???? Would GREATLY appreciate some advice on this.

Until now, the path-header (including nat-ping script) works as a charm for me, but this will probably make my loadbalancer much cleaner :-) br hw -- Helge Waastad Senior Konsulent Systemavdelingen Smartnet _______________________________________________ Devel mailing list Devel(a)openser.org http://openser.org/cgi-bin/mailman/listinfo/devel
