Dear users, I'm using kamailio in the following scenario: 1. A call comes in and is checked against PDT module. From this module depend from the prefix I'm getting back the domain which is used as the dialplan group. 2. After that the call is checked against Dialplan module using the previous value from PDT as Dialplan dpid. From the Dialplan module i get back the the attributes values. 3. these attributes values are user in the dispathcher module where I continue with failover scenarios. Also the script is working with a radius for accounting purposes. This scenario works perfecttly and it is still in a testing mode. An the problem: I'm running SIPP against this scenario and until the CPS is 5 everything looks good. The scenario for SIPP is the simplest. uac and uas default. Uac is sending a call and uas is answering. When the CPS goes above 9 then I have call failures. All the statistics are going down. I'm cheking for CPU load or other system problems but I don't see anything strange. Does anyone understand why this is happening? I'm attachng the 2 routes that i'm using: test values in order to understand the script *PDT value = 1 (used for the dialplan group) Dialplan value = 100.101.102.# Dispatcher values: 100 = 10.0.0.5 101 = 10.0.0.6 102 = 10.0.0.7* Thank you in advance Alex route[7] { if(prefix2domain("2", "0")) { $var(dial_grp) = $(rd{s.int}); if(dp_translate("$var(dial_ grp)", "$rU/$rU")) { $var(i) = 0; while($(avp(s:dest){s.select,$var(i),.})!="#") { $avp(s:dstgrp) = $(avp(s:dest){s.select,$var(i),.}{s.int}); $var(i) = $var(i) + 1; } $avp(s:user) = $rU; if(ds_select_domain("$avp(s:dstgrp)", "4")) { if($(ru{uri.param,prefix})!=null) { $ru = "sip:" + $(ru{uri.param,prefix}) + $rU + "@" + $rd; } else { $ru = "sip:" + $rU + "@" + $rd; } $avp(s:dstgrp) = null; t_on_failure("2"); t_relay(); exit; } } sl_send_reply("404", "No route found"); exit; } } failure_route[2] { if(t_was_cancelled()) { exit; } if(t_check_status("4[0-9][0-9]|5[0-9][0-9]")) { if(ds_next_domain()) { if($(ru{uri.param,prefix})!=null) { $ru = "sip:" + $(ru{uri.param,prefix}) + $avp(s:user) + "@" + $rd; } else { $ru = "sip:" + $avp(s:user) + "@" + $rd; } t_on_failure("2"); append_branch(); t_relay(); exit; } else { if($avp(s:dstgrp)!=null) { if(ds_select_domain("$avp(s:dstgrp)", "4")) { if($(ru{uri.param,prefix})!=null) { $ru = "sip:" + $(ru{uri.param,prefix}) + $avp(s:user) + "@" + $rd; } else { $ru = "sip:" + $avp(s:user) + "@" + $rd; } $avp(s:dstgrp) = null; t_on_failure("2"); append_branch(); t_relay(); exit; } } else { t_reply("444", "No more tries for you!"); } } }

[Kamailio-Users] Reboot phones

by David

Hey, I have noticed that when I try to use kamctl to reboot phones, it comes back with simply "400". I tried using the fifo interface and the phone asked the server to identify itself using the phone's username and password. How do people generally use the kamctl to reboot phones? Thanks, David

[Kamailio-Users] preparing RC3 for kamailio 3.0

by Daniel-Constantin Mierla

Hello, I plan to release Kamailio 3.0, hopefully today, if no outstanding issue out there. Ending of last week, I managed to get debian packaging working (tested on Ubuntu) using Andrei's new Makefile system, with module groups. If you are aware of issues you want fixed before 3.0RC3, drop an email. This is supposed to be latest RC before full 3.0.0 release. Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] Bflags

by David

Hey, I am having some issues with NAT and I think the issue is with Bflags. So I have some clarifications : 1. What does the flags column in location contain? 2. What does the cflags column in location contain ? I am guessing that cflags represents the bflags? So if I have a value of 192, does that mean flags 7 and 8 are set ? This confuses me cause I set flags 6 and 7. Do the bflags appear magically in the routing scripts or is there a command that I have to execute for the script to have the bflags? Thanks! David

What to download?

by Antonio Goméz Soto

Hi, I'm a longtime asterisk user, needing to scale up. I figured it would be smart to use and develop for sip-router, because it'll come out soon. But I've never used one of ser, openser, or siblings, and now I'm confused by the download links on you site. I see kamailio_3.0, master, sr_3.0, stable and unstable top level directories. What should I download? What's the diference between them? Thanks, Antonio

[Kamailio-Users] Rewrite $tU

by David

Hey, I need to rewrite the $tU variable on a packet before it is relayed. It is ok if the change is only on the relayed packet and the $tU variable change. The important thing is that I modify the To header, it seems that rewritting $tU would be the easiest. I know that user agents do not like this changing, but I am changing it on an intermediary server and when the reply comes back, I change it back to the original value. Thanks! David

Case sensitivity in usrloc "location" table

by Bruce McAlister

Hi All, I am trying to integrate Kamailio (1.5.2-notls) into our existing database structure using a view for the subscriber table and using the location table to store the registration information. I am successfully able to register a phone using this method. One of our requirements is to set an "outboundproxy" and "outboundproxyport" parameter in the location table for a particular sip account (username). I am trying to do this with the sqlops module. What I have come across though is that when the registration information is saved to the location table the username is stored in lower case. So when my sqlops query is run against the username it does not match. Is there a way to tell the usrloc module to store the username in the same case as it is received? For example, in the subscriber table I have view defined that for my user account returns the following information: ------------- select * from subscriber where username = 'BruceNW9440'; username | domain | password | ha1 | ha1b -------------+---------------+------------+----------------------------------+---------------------------------- BruceNW9440 | 10.10.10.10 | 00minger00 | 1f2d688f65be04a61cab36a1fb3f426a | 6529d45f5c418daf35be7b3dd4a858cb (1 row) ------------- Now, if I check the above against the location table: -------------- select * from location where username = 'BruceNW9440'; 0 rows returned -------------- If I run the same query using "brucenw9440" as the username (lowercase) then the correct information is returned. I have the following log line in my kamailio configuration script: xlog("L_INFO","Username: $au, OutboundProxy: $Ri, OutboundProxyPort: $Rp"); The details of this log appear correct when it is logged: Dec 9 14:21:03 ibis /opt/kamailio/sbin/kamailio[16972]: [ID 197553 local0.info] Username: BruceNW9440, OutboundProxy: 10.10.10.10, OutboundProxyPort: 5060 However, when my sqlopt query is run it does not find a match because of the incorrect case: sql_query("bfl", "UPDATE location SET outboundproxy = '$Ri', outboundproxyport = '$Rp' WHERE username = '$au'", "res"); I've had a read through the usrloc module documentation and I cannot seem to find a reference to any options that will preserve the case. I also cannot find if there is a parameter to save('location') that will preserve the case. I cant seem to find a reference to the save() function on the wiki. I must be missing something small. We have some sip usernames that are case sensitive so any help in being able to resolve this would be greatly appreciated. Thanks Bruce

[Kamailio-Users] Question regarding TM module DNS failover with SRV records

by Nathan Angelacos

According to the 1.5.x TM module documentation, DNS failover is triggered by a 503 reply or a timeout. When using SRV records, it appears a 503 triggers the failure_route instead. Given: host -t srv _sip._udp.voip.example.net _sip._udp.voip.example.net has SRV record 1 0 5060 fast-server.example.net. _sip._udp.voip.example.net has SRV record 2 0 5060 slow-server.example.net. On an invite to voip.example.net, if fast-server does not respond within "fr_timer" seconds, t_relay fires off a serial branch (t_on_branch is triggered) and the invite goes to slow-server. If fast-server responds with a 503, the t_on_failure route is triggered instead, and the invite is not sent on to slow-server. If its not a bug in the module, does anyone have clues of how to coax the next DNS SRV record out of the t_on_failure route? Or what can be done to get t_relay to consume the 503? Thanks!
