Hello again.
Compiling from source, using the proxy-to-central registrar configurations outlined here http://www.kamailio.org/docs/modules/4.0.x/modules/outbound.html and adding in the additional "append_hf("Supported: path, outbound\r\n");" on the proxy, registration works.
However, when a call is made, the debug traces show problems when entering this area of the configuration outlined in the Outbound Module:
if (!t_load_contacts()) { send_reply("500", "Server Internal Error"); exit; }
if (!t_next_contacts()) { send_reply("500", "Server Internal Error"); exit; }
as shown here: 1(26960) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=700 a=16 n=if 1(26960) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=695 a=24 n=t_load_contacts 1(26960) DEBUG: tm [t_serial.c:166]: t_load_contacts(): nr_branches is 0 1(26960) DEBUG: tm [t_serial.c:169]: t_load_contacts(): nothing to do - only one contact! 1(26960) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=705 a=16 n=if 1(26960) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=700 a=24 n=t_next_contacts 1(26960) DEBUG: tm [t_serial.c:376]: t_next_contacts(): no contacts in contacts_avp - we are done! 1(26960) ERROR: *** cfgtrace: c=[//etc/kamailio/kamailio.cfg] l=701 a=26 n=send_reply
The result from t_load_contacts seems to imply one contact exists, which would be correct as there should be one, but then t_next_contacts sees no cotacts and the sever returns an error, breaking the call.
Any ideas?
