How to detect there are no matching subscriber for uri
by Krishna Kurapati 12 Feb '13

12 Feb '13

Hi, When we receive an request, we do " lookup("location") call to find if the uri is there or not. There are two scenarios: 1. The aor is in the subscriber table but not in usrloc table 2. The aor is not in subscriber table I would like to respond differently to the sender in each of these cases. Right now, the lookup returns -1 for either case. Is there any other way other than dipping into database each time? Thanks Krish Kura

by Bayram Karagoz 12 Feb '13

Hello, I'm trying to limit all subscriber's active call according to setting their simultaneous use setting defined in database. But having problem when one subscriber's INVITE message goes to retransmission. When retranmission occures INVITE messages don't complete with BYE and subscriber simultaneus use amount will hung. My example code block is below. Does anyone advice me for overcome INVITE retransmissions? Thanks. modparam("dialog", "db_url", "mysql://openser:openserrw@localhost/openser") modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_mode", 1) modparam("dialog","profiles_with_value","callquota") modparam("dialog", "default_timeout", 3600) modparam("dialog", "dlg_match_mode",0) modparam("dialog", "detect_spirals", 1) route[QUOTA] { if (is_method("INVITE") && $fU == $avp(s:username)) { avp_db_query("select quota from subscriber where username='$avp(s:username)'", "$avp(s:quota)"); $var(SIZE) = 0; get_profile_size("callquota", "$avp(s:username)", "$var(SIZE)"); xlog("L_INFO", "CALL_OPENSER:Call originated from = $fd\n"); xlog("L_INFO", "Active call amount for $fU is $var(SIZE) , quota=$avp(s:quota)\n"); if( $var(SIZE) >= $avp(s:quota) ){ sl_send_reply("403", "Simultaneous calls limit reached"); xlog("L_INFO", "QUOTA:Limit of $var(SIZE) active calls has been reached for user=$avp(s:username), quota=$avp(s:quota)\n"); exit; } set_dlg_profile("callquota","$avp(s:username)"); get_profile_size("callquota", "$avp(s:username)", "$var(SIZE)"); } } -- *Bayram KARAGÖZ*

Perhaps dlg flag vs dlg_manage has to be clarified a bit more in the next major release (4.1).

Kamailio multiple registration issue
by Ramaseshi reddy kolli 11 Feb '13

11 Feb '13

Hi, i am using kamailio 3.3 version please help me with this issue. 1) Registered from SIP end point, kamailio added row in location table 2) Now using same SIP account details, pushed registration entry using *kamctl ul add , * instead of overwriting the previous contact by new one it inserts another new row in the location table 3) Total now 2 rows with same username are present in DB. I am using save("location", "0x04") so before inserting new row it should check whether already entry is there or not, if there should update the same row. I look forward to your reply. Thanks Ram

Usually the dlg_manage() should be executed just before relaying, when is no other chance that the invite will get a negative reply from the config.

Kamailio-Java Integration
by ron.kamailio＠mcleodnet.com 10 Feb '13

10 Feb '13

I am looking for a way to integrate Java business logic with Kamailio to influence routing decisions, add/remove/modify headers, record accounting-related information, etc. A while back there was a project named WeSIP, but it doesn't appear to active anymore. Is anyone doing something like this now, or any ideas or suggestions? Thanks, Ron
