Duplicate INVITE Handling
by Geoffrey Mina 30 Aug '10

30 Aug '10

Hello, I have a question about what the proper way to handle a duplicate presentation of an INVITE is. On occasion I am seeing some packet loss and/or timing issues which are causing some of my end-points to retransmit the INVITE. Here is what I am doing in the most basic sense: ITSP (Bandwidth.com) --> INVITE --> KAMAILIO --> DISPATCHER --> Asterisk (B2BUA) I am seeing Bandwidth.com send an INVITE which I already received. I keep track of all running transactions in a htable which has a key of $ci::$cs::$ft (as per RFC 3261). If I get an invite for something which already has a key in the hashmap, I am currently sending a "482 Loop Detected", but I don't think that is correct as it causes the whole call to tear down instead of letting it continue and assuring Bandwidth.com that I received the initial INVITE and am currently working on it. This is what I am currently doing: ## ## Check to make sure we don't already have an active ## transaction for this call-id, c-seq, and from-tag ## RFC3261 - 8.2.2.2 ## ## We are going to add a key for this unique record if one ## doesn't already exist. The key automatically times out ## after 30 seconds, so we need not worry about cleanup ## if($sht(loop_check=>$ci::$cs::$ft) == null){ xlog("L_INFO","No transaction found, adding to our hashtable\n"); $sht(loop_check=>$ci::$cs::$ft) = 1; }else{ xlog("L_ERR","Loop Detected: $ci::$cs::$ft\n"); sl_send_reply("482","Loop Detected - Duplicate Session Presentation"); exit; } Can I just swallow the second INVITE and do an exit; in my script? Should I do an sl_send_reply(100,"Trying")? Any advice would be greatly appreciated. Thanks,

load_credentials PVs
by Alex Balashov 30 Aug '10

30 Aug '10

Is there a particular reason why in the 'load_credentials' parameter to the 'auth_db' module, one can only store values in AVPs, not script variables? e.g. this works: modparam("auth_db", "load_credentials", "$avp(s:var1)=column") But not this: modparam("auth_db", "load_credentials", "$var(var1)=column"); it results in an error like this: Aug 28 19:00:54 diminuendo-1 /usr/local/sbin/kamailio[19651]: ERROR: auth_db [aaa_avps.h:113]: malformed or non AVP $var(auth_user_id) AVP definition Aug 28 19:00:54 diminuendo-1 /usr/local/sbin/kamailio[19651]: ERROR: auth_db [aaa_avps.h:179]: parse failed in "$var(auth_user_id)" at pos 0($var(auth_user_id)) Aug 28 19:00:54 diminuendo-1 /usr/local/sbin/kamailio[19651]: ERROR: auth_db [authdb_mod.c:208]: failed to parse credentials Aug 28 19:00:54 diminuendo-1 /usr/local/sbin/kamailio[19651]: ERROR: <core> [sr_module.c:874]: init_mod(): Error while initializing module auth_db -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

Hi, I some calls to a specific `sub-region` that I want to limit to a specific trunk. Example. Region 1: prefix 55, trunk 1, priority 10 Region 1: prefix 55, trunk 2, priority 20 Sub-region A: prefix 5512, trunk 1, priority 30 I do not want the calls to prefix 5512 to fail-over to trunk 2 in case of 404, 503 or the like. So I have tried to put priority 30 on sub-region A and a lower priority on Region 1, but it still fails over to trunk 2 - can I prevent this? Thanks! //Anders
