Re: [SR-Users] reg_fetch_contacts for multiple devices registered

Hello, I am getting there! I am not using a branch routing block at present, I am doing modifications using values I pull from the location table. So my question may be slightly different but very much branch related. So I have two contacts; Contact:: <sip:1009@213.123.211.158:15060;transport=udp;registering_acc=91_208_141_34>;q=;expires=60;flags=0x0;cflags=0x0;state=1;socket=<udp:xx.xx.xx.xx:5060>;methods=0xFFFFFFFF;user_agent=<Contact1>;reg-id=0Contact:: <sip:1009@213.123.211.158:5061;transport=udp>;q=;expires=3191;flags=0x0;cflags=0xC0;state=1;socket=<udp:xx.xx.xx.xx:5060>;methods=0xFFFFFFFF;received=<sip:213.123.211.158:49827>;user_agent=<Contact2>;+sip.instance=<urn:uuid:00000000-0000-0000-0000-58bfea20a6bd>;reg-id=0 Then using reg_fetch_contacts I get for each registered contact; xlog("callee=>user_agent: $(ulc(callee=>user_agent)[$var(i)])\n"); xlog("callee=>received: $(ulc(callee=>received)[$var(i)])\n"); xlog("callee=>addr1: $(ulc(callee=>addr)[$var(i)])\n"); And define some variables as a result for each contact; $var(ua1) = $(ulc(callee=>user_agent)[$var(i)]); $var(ua1add) = $(ulc(callee=>received)[$var(i)]); $var(ua1aor) = $(ulc(callee=>addr)[$var(i)]); I then use these to set $du and $ru in the main routing, I do this for contact2 above, so I send to the recieved port (49827), identifying this by user agent type. This works fine however branch[0] was sending an INVITE TO 1009@213.123.211.158:5061, contact2 also, and not contact1 (port 15060), so I have added; $(branch(dst_uri)[0]) = $var(ua1aor); So I now get parallel forking as follows; INVITE sip:1009-@213.123.211.158:49827 < This is what I want, for Contact2INVITE sip:1009-@213.123.211.158:15060 < Again routes to Contact1 after modifiying the branch parameter.INVITE sip:1009-@213.123.211.158:5061 < Still sends out original branch value. And can see from debug, my branch [0] is modifed, but branch [1] is also created; new branch [0] to sip:1009@213.123.211.158:49827new branch [1] to sip:1009@213.123.211.158:5061 So I now have 3 invites for 2 devices. Whats the best approach to clean this up or implement in the first place, my main question is probably around branch modification/control. Thanks, sorry for long question.

Cheers, Daniel On 13/05/14 13:28, Jonathan Hunter wrote: Hi Guys, Following on from my initial query, I have indexing working for reg_fetch_contacts, however now I am having issues with branching. First, is append_branches() still applicable to kamailio 4.0.6 ? As when I use its not recognised. Also I have two contacts registered, contact 0 and contact 1. Contact 0 was registered first, then contact 1. Now I perform manipulation on the main branch after identifying the user agent for contact 1, and the main branch request is sent out as I wish, this uses branch [0] when running debug to the $ru/$du I have modified. However with branch [1] this isnt modified which is fine, but uses the contact AOR from Contact 1 and not Contact 0. Is this normal behaviour and I just need to improve my logic? Any advise on parallel branching where you extract certain credentials from location table, then as a result manipulate the $ru and $du as a result, but dont affect any other multiple registrations that would be great! Many thanks Jon Hi Guys, I was wondering if anyone could help? I am currently using reg_fetch_contacts to manipulate signaling based on the user agent device being used, therefore I use the result of; if(reg_fetch_contacts("location", "$ru", "callee")) { xlog("callee=>user_agent $ulc(callee=>user_agent)\n"); } I then use $ulc(callee=>user_agent) to make routing decisions. This seems to only return the user-agent device being used for the first registration at that AOR, as I have two devices registered, a Cisco, and a jitsi client, and it only returns the user_agent of the jitsi client I registered first. Is it possible to return the user agents of all the devices registered against an AOR so I can manage decisions accordingly?
