Hi All, I have an issue that I cant seem to get to the bottom of, I would appreciate if someone could point me in the right direction. I have 3 registrar's and would like to replicate the registration regest from 1 to the other 2, I am trying this with t_replicate, the docs say that to send to multiple destinations an append_branch should be performed prior to the t_replicate, which is what I am trying to do. What appears to happen is that the replication only sends the REGISTER to the server defined in the t_replicate command, it doesnt appear to be sending it to the destination defined in append_branch.

Am I doing something wrong here? Thanks Bruce

Hello, looking a bit at the source code, append branch should still create a new destination point and message to be sent there. I would need the log messages printed with debug=3 in kamailio.cfg for the case when you use append branch. Can you provide them?

The second one is with the patch to the code and it is enough to pick only that one.

OK, I tried 4.1.4 with this patch applied and I still get the following error message: /usr/sbin/kamailio[22158]: ERROR: tm [tm.c:1618]: t_replicate_uri(): bad replicate SIP address!
