force_send_socket - multiple times per dialog, subsequent times fail

by Geoffrey Mina

I am having an issue with 1.5.4 where force_send_socket() isn't behaving as I would expect. I have an LCR scenario where depending on which gateway I am sending to, I send from a different socket. It appears that calling force_send_socket from failure_route has no affect on the routing. In my initial route block I call force_send_socket(X.X.X.180:5060). In my failure_route I am calling force_send_socket(X.X.X.179:5060), yet after calling the subsequent time, my sip trace and tcpdump are clearly showing kamailio is still sending from X.X.X.180:5060. I have added a lot of debug lines, so I am 100% sure the second call to force_send_socket is happening. Am I misusing this module in some way?

[nathelper] clarification about rtpproxy_retr parameter

by Iñaki Baz Castillo

Hi, according to the doc: 1.5.9. rtpproxy_retr (integer) How many times nathelper should retry to send and receive after timeout was generated. Default value is “5”. So imagine this configuration: modparam("nathelper", "rtpproxy_tout", 2) modparam("nathelper", "rtpproxy_disable_tout", 60) modparam("nathelper", "rtpproxy_retr", 10) Let's imagine that the RtpProxy servers crashes and is down for 1 day. Does this configuration mean that the rtpproxy server will NEVER be contacted again by nathelper module since 60x10 seconds < 1 day? Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Dispatcher module problem or feature?

by JR Richardson

Hi All, I'm testing dispatcher functions with kamailio 3.0 and using database to load destination address. The problem I am seeing is the 1'st destination address in a group is not being used, the dispatcher always starts at the second database entry. For instance, if I have 2 destination addresses listed in the database, sip:10.10.14.101:5060 and sip:10.10.14.102:5060, only sip:10.10.14.102:5060 will receive calls. But if I list .101 in the database twice, then I will get proper distribution. So here is my setup and some debug traffic: sipp><sr-router><dispatcher round robin group 1><10.10.14.101, 10.10.14.102, 10.10.14.101 This will send calls to both .101 and 102 evenly. sip-router2:~# kamctl fifo ds_list SET:: 1 URI:: sip:10.10.14.101:5060 flag=A URI:: sip:10.10.14.102:5060 flag=A URI:: sip:10.10.14.101:5060 flag=A first call to dispatcher: 0(4780) DEBUG: dispatcher [dispatch.c:1111]: set [1] 0(4780) DEBUG: dispatcher [dispatch.c:1185]: alg hash [0] 0(4780) DEBUG: dispatcher [dispatch.c:1223]: selected [4-1/0] <sip:10.10.14.101:5060> 0(4780) DEBUG: dispatcher [dispatch.c:1257]: using entry [1/1] 0(4780) INFO: <script>: ds_dispatcher sip:10.10.14.101:5060 1 3 second call to dispatcher: 0(4780) DEBUG: dispatcher [dispatch.c:1111]: set [1] 0(4780) DEBUG: dispatcher [dispatch.c:1185]: alg hash [1] 0(4780) DEBUG: dispatcher [dispatch.c:1223]: selected [4-1/1] <sip:10.10.14.102:5060> 0(4780) DEBUG: dispatcher [dispatch.c:1245]: using entry [1/0] 0(4780) INFO: <script>: ds_dispatcher sip:10.10.14.102:5060 1 3 third call to dispatcher goes back to .101, then .102, ect. sipp><sr-router><dispatcher round robin group 2><10.10.14.103 and 10.10.14.104 This will send calls only to .104 sip-router2:~# kamctl fifo ds_list SET_NO:: 2 SET:: 2 URI:: sip:10.10.14.104:5060 flag=A URI:: sip:10.10.14.103:5060 flag=A first call to dispatcher: 0(4780) DEBUG: dispatcher [dispatch.c:1111]: set [2] 0(4780) DEBUG: dispatcher [dispatch.c:1185]: alg hash [0] 0(4780) DEBUG: dispatcher [dispatch.c:1223]: selected [4-2/0] <sip:10.10.14.104:5060> 0(4780) INFO: <script>: ds_dispatcher sip:10.10.14.104:5060 2 2 second call to dispatcher: 0(4780) DEBUG: dispatcher [dispatch.c:1111]: set [2] 0(4780) DEBUG: dispatcher [dispatch.c:1185]: alg hash [1] 0(4780) DEBUG: dispatcher [dispatch.c:1223]: selected [4-2/0] <sip:10.10.14.104:5060> 0(4780) INFO: <script>: ds_dispatcher sip:10.10.14.104:5060 2 2 So it appears with only 2 entries loaded in the database, there is a missing "DEBUG: dispatcher [dispatch.c:1245]: using entry [1/0]" This is the only difference I can see between the call executions between the two groups. But I don't really know what that means. I can reproduce these symptoms on kamailio 3.0, 1.5.x and older versions. The same thing happens when the destinations are loaded via config file dispatcher.lst. I am using debian Lenny with siremis web interface. mysql> select * from dispatcher\G; *************************** 1. row *************************** id: 1 setid: 1 destination: sip:10.10.14.101:5060 flags: 0 priority: 0 description: lab1 *************************** 2. row *************************** id: 2 setid: 1 destination: sip:10.10.14.102:5060 flags: 0 priority: 0 description: lab2 *************************** 3. row *************************** id: 3 setid: 2 destination: sip:10.10.14.103:5060 flags: 0 priority: 0 description: lab3 *************************** 4. row *************************** id: 4 setid: 2 destination: sip:10.10.14.104:5060 flags: 0 priority: 0 description: lab4 *************************** 5. row *************************** id: 5 setid: 1 destination: sip:10.10.14.101:5060 flags: 0 priority: 0 description: lab1 5 rows in set (0.00 sec) Is this a bug?

Permissions module question?

by JR Richardson

Hi All, Kamailio 3.0 permissions module, I see that the address database table is cached by default, really the only option. But there is no MI Function to reload the database into cache, you must restart kamailio to update the cache for the address table. Is there any reason the reload MI function is not there for the address table? It is present for the trusted table and works fine. I like the trusted db option to use cache or no cache, I'm wondering if this option can be extended to the address table as well? Also I like the address table ability to define subnets, can this be extended to the trusted table? Thanks. JR -- JR Richardson Engineering for the Masses

New functionality LCR + force_send_socket() - sanity check

by Geoffrey Mina

Hey everyone, Just wanted to bounce some things off the list to make sure I'm not heading down the wrong path here. I'll quickly explain my problem and then explain my plan to deal with it. Please let me know if anyone sees an issue here. Problem: I need to send FROM two different IP addresses based on the LCR group returned from next_gw();. For example, if the gateway returned is in group_id=1 from the LCR I need to send FROM 1.1.1.1:5060, if it's from group_id=2, I need to send FROM 1.1.1.2:5060. I need to do this on REQUEST_ROUTE and FAILURE_ROUTE. Here is what I am thinking will work: modparam("pv","shvset","gw_one=s:1.1.1.1:5060") modparam("pv","shvset","gw_two=s:1.1.1.2:5060") route{ load_gws(); next_gw(); if(to_gw("1")){ force_send_socket($shv(gw_one)); }else if(to_gw("2")){ force_send_socket($shv(gw_two)); } } Sorry for not just trying this out on my own. I currently don't have access to a dev machine, and I need to make changes to the live script... so I would prefer not to have a ton of restarts while trying to work the bugs out. Thanks.

Check for existence of URI param

by Alex Balashov

Greetings, I have a Contact URI with params as in the following form returned to me in a 302 Moved Temporarily reply: <sip:a=foo;b;c=bar> I am able to check the existence of parameters 'a' and 'b', which have values assigned to them, in the following way: failure_route[...] { ... $var(dest) = $T_rpl($ct); $var(dest) = $(var(dest){nameaddr.uri}); $var(dest) = $(var(dest){uri.user}); ... if(! $(var(dest){param.value,a})) { .... } ... } However, what I cannot seem to figure out is a reliable test condition for the existence of a parameter like 'b', which does not have a value. I have tried: if(! $(var(dest){param.value,b})) which clearly cannot work as the parameter has no _value_. Also have tried: if(!defined $(var(dest){param.value,b})) and also tests of strempty(), !defined, etc. for $var(dest){uri.param,b}) (prior to extraction of param list using {uri.user} above). Ideas appreciated, thanks! -- 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/
