wiki: upgrade from 3.0.x to 3.1.x
by Daniel-Constantin Mierla 17 Apr '10

17 Apr '10

Hello, I started the page that should collect notes about how to upgrade from version 3.0.x to 3.1.0: http://sip-router.org/wiki/install/3.0.x-to-3.1.x 3.1.0 is not yet released, target date is September 2010, right now is the code on master branch in GIT repository. However, this page will help people that want to test it or use some modules from it, making as well the life easier before release. Please add to the document as you change (or discover) something breaking compatibility with 3.0.x - the wiki is open. Thanks, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/ * http://twitter.com/miconda * http://www.linkedin.com/in/danielconstantinmierla

reply when drop() in branch route
by jh＠tutpro.com 17 Apr '10

17 Apr '10

i call drop() in branch route and it is the only branch left. the branch gets correctly dropped, i.e., the request is not send out, but the reply to UAC is strange: U 2010/04/14 21:03:43.750712 192.98.102.10:5060 -> 192.98.103.2:5074 SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/TM). Via: SIP/2.0/UDP 192.98.103.2:5074;rport=5074;branch=z9hG4bKaoxzewgj. To: <sip:0407058055@192.98.102.10>;tag=c02670ad1171fe45d9ff9a27d6c2cb82-e03b. From: <sip:+35816234567@foo.bar>;tag=bclsw. Call-ID: doibilvynrtqxpk@localhost. CSeq: 134 INVITE. Server: SIP Proxy (3.0.99-dev1 (i386/linux)). Content-Length: 0. why this kind of reply, because the proxy didn't even try to send the request to next ho? is it possible to somehow choose in the script, which reply to send? in this example, i'm using lcr to choose gws and none of them was suitable, so something like '503 service not available' would be more appropriate. -- juha

Please, keep the mail within the maillist thread. No, it doesn't add too much load to Kamailio. This is one of the major purposes of a transaction stateful proxy (the serial forking in order to implement failover). Take a look to the LCR module. It gives you load balancing (with priorities if you want) and failover features. It's all you need in your scenario. -- Iñaki Baz Castillo <ibc(a)aliax.net>

call not being accounted when rejected by global blacklist
by Panagiotis Skoulikaritis 15 Apr '10

15 Apr '10

Dear list members I'm using kamailio 3 and the problem that I'm facing is that when a call is rejected by global blacklist, kamailio does not generate an accounting record. Is this normal behavior or I need to configure something somewhere ? Below are parts of the config file # ----- acc params ----- modparam("acc", "early_media", 1) modparam("acc", "report_ack", 1) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 0) modparam("acc", "failed_transaction_flag", 3) #!ifdef WITH_ACCDB modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "db_url", "mysql://username:password@localhost/openser") modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") #!endif ---------------------- if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if (is_method("BYE")) { setflag(1); # do accounting ... setflag(3); # ... even if the transaction fails } ------------------------- if (is_method("INVITE")) { setflag(1); # do accounting setflag(2); # log missed calls setflag(3); # log failed calls setflag(4); # do siptrace setflag(5); # log dialog ------------- route[name] { # --- Remove # or %23 from rU --- bm_start_timer("hash_remove"); if($rU =~ "^.*%+") { xlog("------- The number contains %23 ---- "); $rU = $(rU{re.subst,/^(.*)%23(.*)/\1\2/}); xlog(" ------- The perl $rU ------- "); } if($rU =~ "^.*#+") { xlog("------- The number contains # ----"); $rU = $(rU{re.subst,/^(.*)#(.*)/\1\2/}); xlog("------- The perl $rU ------- "); } bm_log_timer("hash_remove"); # --- PDT section ------ get service prefix to be appended before is send out bm_start_timer("pdt_lookup"); if(!prefix2domain("2", "0")) { sl_send_reply("404", "Prefix not found"); exit; } $var(dstgrp) = 0; $var(dstgrp) = $(rd{s.int}); if($var(dstgrp)==0) { sl_send_reply("404", "Service not found"); exit; } $avp(s:service_prefix) = $var(dstgrp); xlog("--$rU----------- $avp(s:service_prefix) --- PDT ---------\n"); bm_log_timer("pdt_lookup"); # --- DialPlan section --- get the routing group id xlog("----- The rU is $rU before DP -----\n"); bm_start_timer("dialplan_lookup"); if(dp_translate("1", "$rU/$rU")) { $avp(s:dstgrp) = $(var(dpattrs){s.int}); xlog("----- The destination Drouting GroupID is $avp(s:dstgrp) -----\n "); } bm_log_timer("dialplan_lookup"); xlog("----- The rU is $rU after DP -----\n"); # --- Global Blacklist section --- bm_start_timer("blacklist_lookup"); if(!check_blacklist("globalblacklist")){ xlog("----- The number is blacklisted globaly! -----"); sl_send_reply("403", "Forbidden"); exit; } bm_log_timer("blacklist_lookup"); # --- Dynamic routing section --- route the call based on the routing group id bm_start_timer("drouting_lookup"); if (!do_routing("$avp(s:dstgrp)")) { xlog("----- DRouting don't match dstgrp $avp(s:dstgrp) -----\n"); sl_send_reply("404","Route Not Found -$rU-"); exit; } bm_log_timer("drouting_lookup"); xlog("-----DRouting with $rU and $avp(s:dstgrp) -and $avp(s:service_prefix)----\n"); # Append service prefix in front of number $ru = "sip:" + $avp(s:service_prefix) + $rU + "@" + $rd; xlog(" ------ $ru ----$rU- $avp(s:user)---\n"); t_on_failure("FAIL_ONE"); route(RELAY); exit; return; } Regards Panagiotis

[Kamailio-Users] PKG memory issues
by Iñaki Baz Castillo 15 Apr '10

15 Apr '10

Hi, I've experimented PKG out of memory in a production server. Of course I'm already increasing such value but I would like to know if the current settings and traffic could run into PKG memory issues: - Dual core INTEL XEON 3.00 GHz server. - Kamailio PKG memory = 4 MB. - Kamailio Shared memory = 64 MB. - Kamailio just listens in a single UDP port (8 childrens). - Just INVITE method is handled (no registration, no subscription). The script does the following for each request: - 'permissions' module to match source IP (just ~20 entries in 'address' table). - 2 custom SQL queries (returning a simple value). - 'dialog' memory (just in memory). - 'uac' module to change From header. - There are 10 AVP's set per transaction. - 'lcr' module for routing to two gateways (just 2 entries in 'lcr' table). - 'rtpproxy' is forced for every call. The server has been working properly for months but these days the traffic has been duplicated, having ~400 simultaneous calls in peak hours. Also note that such calls come from callcenters so they are ver "fast". With this environment, is it normal to get into PKG memory issues (4 MB)? I understand that it makes sense, but I would like to hear some opinions. Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Re: [SR-Users] Failure to load module db_mysql.so due to undefined symbol: log
by Pratab Ali 14 Apr '10

14 Apr '10

Hello Marius, Yes, I can confirm that MySQL-devel-community-5.1.43-1.sles10.i586.rpm was also installed. I think the log_10_int is included by something that's linked in and has nothing to do with MySQL. A colleague and friend has installed on a Debian system with success. I am about to install Debian over my SuSE installation. Thanks Pratab. -----Original Message----- From: marius zbihlei [mailto:marius.zbihlei@1and1.ro] Sent: 14 April 2010 14:34 To: Pratab Ali Subject: Re: [SR-Users] Failure to load module db_mysql.so due to undefined symbol: log Pratab Ali wrote: > Hello > > My version of libmysqlclient was installed from this file > MySQL-client-community-5.1.43-1.sles10.i586.rpm.

Can you check if this is also installed . I have tested on Debian with libmysqlclient-dev 5.1.45 and it works. I still wonder about the log_10_int symbol...
