[Kamailio-Users] Problems with parallel forking to different users
Hi all, I'm trying to implement parallel forking to different users registered on a Kamailio server. I want to fork the call to a number of different users (not including the called user). To do this I added the piece of code below to the default 3.0.0 config file: ... # account only INVITEs if (is_method("INVITE")) { setflag(1); # do accounting setflag(4); #dialog aware if(avp_db_load("$ru/username","$avp(s:fork)")) { avp_pushto("$ru/username","$avp(s:fork)/g"); }; } .... This is usr_preference table content: +----+------+----------+--------+-----------+------+-------+---------------------+ | id | uuid | username | domain | attribute | type | value | last_modified | +----+------+----------+--------+-----------+------+-------+---------------------+ | 4 | | 1000 | | fork | 0 | 1001 | | | 3 | | 1000 | | fork | 0 | 1005 | | +----+------+----------+--------+-----------+------+-------+---------------------+ Kamailio correctly forks the call to 1001 and 1005, but the Request-URI of the 1005 user is not correctly set, because the proxy IP is used instead of the IP where the user is registered (10.1.2.15). You can see the INVITEs below. Could anybody tell me what I'm doing badly?

This is usr_preference table content:

Kamailio correctly forks the call to 1001 and 1005, but the Request-URI of the 1005 user is not correctly set, because the proxy IP is used instead of the IP where the user is registered (10.1.2.15). You can see the INVITEs below.
Could anybody tell me what I'm doing badly?
apart of first destination which is set in the r-uri, the rest become branches. You have to loop back so they arrive as r-uri and location lookup resolves the user address. lookup("location") works only with r-uri. Cheers, Daniel
Thanks for your time, best regards
