Carrierroute failover domain not working
by JR Richardson 27 May '10

27 May '10

Hi All, I'm testing carrierroute modue in kamailio 1.5.4-notls (i386/linux). I have things working like this: sipp><kamailio carrierroute>< 2 asterisk servers A & B even distribution of calls So A & B are in carrier1 domain1, I have failureroute setup with 2 more asterisk servers C& D in carrier1 domain2. While I'm processing calls from sipp and sending to A & B, I can fail A and then all calls go to B as expected. But if I fail both A & B, the calls fail, so I'm guessing I don't have the faliure_route configured correctly. Here is my current config: route { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if ($rU==NULL) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!allow_trusted()) { sl_send_reply("403", "Forbidden"); exit; }; if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } t_check_trans(); route(2); } route[1] { if (!t_relay()) { sl_reply_error(); } exit; } route[2] { if(!cr_route("1", "1", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); } else { t_on_failure("2"); route(1); } } failure_route[2] { if (t_check_status("408|5[0-9][0-9]")) { if(!cr_route("1", "2", "$rU", "$rU", "call_id")){ t_reply("403", "Not allowed"); } else { t_relay(); } } } I think the database entries are setup ok, I used the example in the module doc, but I can share that if needed. Any guidance will be appriciated. Thanks. JR -- JR Richardson Engineering for the Masses

Siremis 1.0 login fails (or, does nothing)
by Joe Micciche 27 May '10

27 May '10

RHEL5.5 server Kamailio 3.0 built from source via Git Apache/2.2.3 PHP 5.3.2 MySQL 5.1.47 chown -R apache /var/www/html/siremis-1.0.0, apache is the httpd user. Used the instructions from Asipto's site for Siremis install and configure, added the alias to httpd.conf, Config.xml is: <?xml version="1.0" standalone="no"?> <Config> <DataSource> <Database Name="Default" Driver="Pdo_Mysql" Server="127.0.0.1" DBName="openser" User="openser" Password="*****" /> <Database Name="Siremis" Driver="Pdo_Mysql" Server="127.0.0.1" DBName="openser" User="openser" Password="*****" /> </DataSource> </Config> I navigate to the Siremis page, http://10.5.10.21/siremis/ and get the login screen, enter the login credentials, Submit, and nothing happens. httpd/error_log: [Wed May 26 12:49:45 2010] [error] [client 10.3.226.168] File does not exist: /var/www/html/siremis-1.0.0/siremis-web/js/sound.js, referer: http://10.5.10.21/siremis/bin/ [Wed May 26 12:49:45 2010] [error] [client 10.3.226.168] File does not exist: /var/www/html/siremis-1.0.0/siremis-web/js/sound.js, referer: http://10.5.10.21/siremis/bin/ I have wiped Siremis and done a fresh install, restarted httpd, and still nothing.

MAX_BRANCHES
by Alex Balashov 27 May '10

27 May '10

This may seem like an absurd question, but is there a particular reason why MAX_BRANCHES is #defined as 12 in config.h? Any particular reason for 12? Is it okay to make it higher? -- 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/

Question about inbound Alias Routing
by dotnetdub 26 May '10

26 May '10

Hi List, At the moment I use dbalias to send inbound from the PSTN <--> subscribers. I have a new opportunity that requires me to send inbound to a URI - SIP/353xxxxxxx(a)customer.proxy - not really sure how to accomplish this. I have a feeling there is a module I should be looking at to do this possibly? If someone could point me in the correct direction. TIA. Stephen.

A Couple of Questions about carrierroute moduel
by JR Richardson 26 May '10

26 May '10

Hi All, I'm testing carrierroute module on version: kamailio 1.5.4-notls (i386/linux). I'm distributing calls to a group of Asterisk servers, all in the same carrier and domain, wanted to load balance the calls and I'm curious how this works. I see the 'probability' parameter in the carrierroute table and set it to equal value across all servers, I have 4 servers I'm sending calls to, so I set each prob value to '0.25'. I'm testing with sipp and hashing over call_id so this is the same for every call. I send 40 calls and the distribution of calls to the asterisk servers are 11, 12, 6, 11, pretty close to even but not 100%. How does the distribution algorithm work for carrieroute? Does it statefully track all active calls and load balance across each server in destination group? Is there another algorithm that can offer that can get closer to a round robin effect? Another question is do I need to include the record_route() and the t_check_trans() functions prior to calling the carrierroute functions? I see in the debug "DBG:core:forward_reply: found module tm, passing reply to it" and dialogs seem to process fine, so does the carrierroute module handle those requirements for stateful processing? Thanks. JR -- JR Richardson Engineering for the Masses

Calculate ha1 with mysql trigger
by Ole Kaas 26 May '10

26 May '10

Hello, When editing the subscriber table using phpmyadmin, updating the ha1 fields are no fun and error prone. The trigger below will calculate the hashes if the input fields are left empty. Navigate to the subscriber table in phpmyadmin and drop the code in the query field under the "SQL" tab. Remeber to set the delimiter to // /Ole DROP TRIGGER IF EXISTS calcha1 // CREATE TRIGGER calcha1 BEFORE INSERT ON subscriber FOR EACH ROW BEGIN IF NEW.ha1 = "" THEN SET NEW.ha1 = MD5(CONCAT(NEW.username,":",NEW.domain,":",NEW.password)); END IF; IF NEW.ha1b = "" THEN SET NEW.ha1b = MD5(CONCAT(NEW.username,"@",NEW.domain,":",NEW.domain,":",NEW.password)); END IF; END//
