A piece of history - 9 years SER
by Daniel-Constantin Mierla 06 Sep '10

06 Sep '10

Hello, fyi, today are 9 years since first source code commit of SIP Express Router (SER) happened. It started with: git log --pretty=format:"%h%x09%an%x09%ad%x09%s" --reverse | head -3 512dcd9 Andrei Pelinescu-Onciul Mon Sep 3 21:27:11 2001 +0000 Initial revision 888ca09 Andrei Pelinescu-Onciul Tue Sep 4 01:41:39 2001 +0000 parser seems to work e60a972 Andrei Pelinescu-Onciul Tue Sep 4 20:55:41 2001 +0000 First working release Today, 3286 days later, it counts 14 200 commits __only__ in development branch. I digested some statistics and made them available at: http://bit.ly/9J4EKb There are interesting facts about most productive time frames (i.e., hour, day, ...), evolution of default configuration files, command line parameters, ... IPv6 support is there since 2002, but no convenient public network to use it yet. Enjoy and enhance the content as you have interesting aspects of history to add... ... and, VERY important, do not forget to start testing 3.1.0, we are in pre-release phase, there are a lot of new features I am sure you want on your production system: http://sip-router.org/wiki/features/new-in-devel Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

help for SIP client configuration
by zed li 05 Sep '10

05 Sep '10

Dear sir, How are you? I have installed SER and it runs well. Now I am adding a SIP client to make phone call. I downloaded SERCTL and up, but do not know to use it. Could you tell me how to install and use the software? Or another way is to add user to the tables in MySQL? could you tell me what tables we are using and how to do it? I am sorry to bother you, but I searched the Internet and have got no clear solution. Best regards Zongyin

failure_route send 500 retry later
by Alejandro Mellado G. 05 Sep '10

05 Sep '10

Hi' I'm trying to forward the call to voicemail on sems when the time of response is out. When the user isn't in location, the forward to voicemail work very fine ( $rc = -1 ). But failure_route, doesn't work and send message "500 Retry Later". I'm using kamailio 3.0.2 and I'm probing with: modparam("tm", "fr_timer", 10) modparam("tm", "fr_inv_timer", 15) ... ... failure_route[FAIL_ONE] { #!ifdef WITH_NAT if (is_method("INVITE") && (isbflagset("6") || isflagset(5))) { unforce_rtp_proxy(); } #!endif if (t_is_canceled()) { exit; } if (t_check_status("486|408")) { revert_uri(); avp_db_load("$ruri","$avp(s:email_address)/$email_scheme"); append_hf("P-App-Name: myvoicemail\r\n"); append_hf("P-App-Param: Email-Address=$avp(s:email_address)\r\n"); rewritehostport("sems_host:5080"); append_branch(); t_relay(); } } Thanks. -- Saluda Atte, Alejandro Mauricio Mellado Gatica Escuela de Ingeniería Informática Universidad Católica de Temuco _________________________________

Question about avp_db_load
by Raúl Alexis Betancor Santana 03 Sep '10

03 Sep '10

Hi all .. I'm trying to change the way avp_db_load works on my current config to load avp's from DB based on $fU and $fd and not based on uuid, so I have try this ... ... modparam("avpops", "avp_table", "usr_preferences") modparam("avpops", "use_domain", 1) ... # load caller avps avp_db_load("$fu/username", "*"); ... With no success .. because the query that is send to the DB is: select value,attribute,type from usr_preferences where username='{$fU value}' instedad of select value,attribute,type from usr_preferences where username='{$fU value}' and domain='{$fd value}' witch is what I expect when using use_domain=1 Any clue about what I'm doing wrong? Best regards -- Raúl Alexis Betancor Santana Dimensión Virtual

Unable to load IPv6 locations

Hi I am doing simple registration test with IPv6 enabled SIP phone. It seems that Kamailio is unable to load back registrations done via v6 socket after restart. Here is (some) content of location table before starting proxy: --- mysql> select username,contact,socket from location; +----------+-----------------------------------------------+---------------------------------+ | username | contact | socket +----------+-----------------------------------------------+---------------------------------+ | ml6 | sip:ml6@[2a00:17b8::55]:5060;line=z79d766z | udp:2A00:17B8:0:0:0:0:0:67:5060 | | ml4 | sip:ml4@89.18.234.88:5060;line=dp77j5yo | udp:89.18.243.167:5060 | --- Here are the error messages during startup: --- 1(26374) DEBUG: usrloc [udomain.c:415]: loading records - cycle [1] 1(26374) ERROR: <core> [main.c:1116]: ERROR: parse_phostport: too many colons in udp:2A00:17B8:0:0:0:0:0:67:5060 1(26374) ERROR: usrloc [udomain.c:314]: bad socket <udp:2A00:17B8:0:0:0:0:0:67:5060> 1(26374) ERROR: usrloc [udomain.c:430]: sipping record for ml6 in table location --- Here are the listen statements from config: --- listen=udp:[2a00:17b8::67]:5060 listen=udp:89.18.243.167:5060 --- DB is MySQL 5.1, OS is Debian Squeeze.

Using multiple media proxy pools
by Stagg Shelton 02 Sep '10

02 Sep '10

I have a requirement that I hope can be accomplished. I have to connect to three providers who will be delivering a private IP Layer 2 ethernet endpoint. I need to be able to direct the SIP calls via Kamailio and have the RTP media process through mediaproxy. I also need to try and avoid using separate physical media proxy machines for each SIP provider. Is it possible to run multiple mediaproxy dispatchers bound to separate IP addresses, and run multiple relays with IP addresses corresponding to the various dispatcher subnets. Basically I want to identify pools of mediaproxy servers and choose them based on the provider origination or termination. Alternatively we could use RTP Proxy, though we do not have as much experience with RTP Proxy. Any suggestions that you may have is appreciated. Thanks Stagg
