Hi, I'm new to kamailio, have some questions here hope anyone can help! Question 1, I'm trying to use some of the functions in usrloc module, but for some reason if I use those from "Available Functions" part, the kamailio won't start and give an error of "unknown command <ul_get_ucontact>, missing loadmodule?" The usrloc module is definitely loaded, and it will start as long as I avoid using those "Available Functions". I tried some other modules it will lead to same error. Question 2, What is the simplest way to bridge a call based on username and domain? I was trying to make a simple experiment I used to do in Freeswitch, ========================== Have 1000,1001,1002 registered, When 1000 calls 9999, the calls will be bridged to 1001 or 1002 based on different time period. ========================== While in Freeswitch, it would be as simple as "bridge xxxx(a)domain.com&quot;quot;, and then freeswitch will lookup contact information and forward the call. But in kamailio, I only succeed in forwarding calls by change the $du to the exact contact uri, which is "sip:xxxx@ip-of-the-phone:port", the call r_relay(). In order to do this, I need call a perl script to lookup the location database to find a match… I'm 99% sure I'm doing wrong here… there must be a way way easier than that, but so far I can't find it…. Please help… Thanks, Xi
