Thanks Daniel. I am now using record_route_advertised_address() to set the alternate address rather than record_route_preset() followed by record_route(). Also, I am able to add the tag using add_rr_param(). The documentation for the record_route_preset function isn't clear that it actually adds the header, so I understood that I needed to call the record_route function as well. record_route(), record_route(string) The function adds a new Record-Route header field. record_route_advertised_address(address) The function adds a new Record-Route header field using the address given. record_route_preset(string [,string2]) This function will put the string into Record-Route Thanks again for your help, Ron From: sr-users [mailto:sr-users-bounces@lists.sip-router.org] On Behalf Of Daniel-Constantin Mierla Sent: January-03-15 1:54 AM To: Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] Double attempt to record-route, RR param not added Hello, you call record_route_preset() in the switch and record_route() before t_relay(), therefore you attempt to add two times the record-route header. I am not sure the add_rr_param() works on the header added by record_route_preset(), to that function you can include the URI parameter directly in the function parameter.

I am having a problem when I try to add a Record-Route header with a tag. I see a message in the log indicating that a Double attempt to record-route was made, and the tag that I specified (;rtpproxy=yes), does not get included. I have checked-over the scripts defined in the kamailio.cfg, and I am very sure that record_route() does not get called more than once. Also, the log only shows record_route being execute a single time. Can anyone suggest how I can troubleshoot this problem further? 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=206 a=57 n=set_adv_addr 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=207 a=58 n=set_adv_port 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=208 a=25 n=record_route_preset 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=209 a=62 n=force_send_socket 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=210 a=2 n=exit 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=235 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=231 a=41 n=isflagset 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=232 a=25 n=add_rr_param 5(32087) DEBUG: rr [record.c:899]: add_rr_param(): rr_param_buf=<;rtpproxy=yes> 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=235 a=25 n=xlog 5(32087) ERROR: <script>: new ru: sip:19999009595@192.168.100.52:5080 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=236 a=24 n=record_route 5(32087) ERROR: rr [rr_mod.c:262]: w_record_route(): Double attempt to record-route 5(32087) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[//etc/kamailio/kamailio.cfg] l=237 a=5 n=route 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=247 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=244 a=25 n=is_method 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=246 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=245 a=25 n=t_is_set 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=245 a=25 n=t_on_branch 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=250 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=247 a=25 n=is_method 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=249 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=248 a=25 n=t_is_set 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=248 a=25 n=t_on_reply 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=254 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=250 a=25 n=is_method 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=252 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=251 a=25 n=t_is_set 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=251 a=25 n=t_on_failure 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=257 a=16 n=if 5(32087) ERROR: *** cfgtrace:request_route=[RELAY] c=[//etc/kamailio/kamailio.cfg] l=254 a=24 n=t_relay The complete log file, script files, and SIP trace can be found here: http://www.siplabs.net/tracebin/record-route/kamailio-log.txt http://www.siplabs.net/tracebin/record-route/kamailio.cfg http://www.siplabs.net/tracebin/record-route/bgcf-local.cfg http://www.siplabs.net/tracebin/record-route/sip-trace.txt Thanks and Happy New Year, Ron -- This email was Anti Virus checked by Astaro Security Gateway. http://www.astaro.com _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
