Proxy Registrations offset port
by Robert 22 Mar '12

22 Mar '12

I've been playing with OpenSIPS and am willing to change over if it means I'll get a more informed answer from this community.. I need to set up a proxy forwarding server that can listen on a port other than 5060 I.e. 8080 and forward the registration requests to another Voip platform we have that is running on 5060. I've been able to do this under OpenSIPS but I'm having issues with inbound calls. It could be a NAT issue. Basically listen on 8080 forward any and all registrations to x:5060 which I've done using rewritehostport Anyone have any good example configs for this? I'm a n00b at this OpenSER stuff but have been around asterisk / freeswitch / portaone for a while. Thanks in advance

Does anyone know how to use Sipp to test Kamailio?
by Jiaxiang Zhou 22 Mar '12

22 Mar '12

Hi I want to do the performance testing on the Kamailio. I found the related document about openser 1.2.0 version at: http://www.kamailio.org/docs/openser-performance-tests/. But somehow, I can't make it work with Kamailio 3.1. Do you happen to know what to do? By following the test case at http://www.kamailio.org/docs/openser-performance-tests/#tm-tests-c, I use the command as below to do the test: ./sipp -sf uac_inv.xml<http://www.kamailio.org/docs/openser-performance-tests/data/uac_inv.xml>-rsa 10.1.11.24:5060 192.10.1.11.24:5081 -m 200000 -r 7000 -d 1 -l 27 where 10.1.11.24:5060 is for Kamailio, and 10.1.11.24:5081 is for sipp uas. In the error log, I got the error message: *********************************************************************'. 2012-03-22 08:55:43:933 1332377743.933861: Aborting call on unexpected message for Call-Id '77062-11425(a)172.16.220.1': while expecting '100' (index 1), received 'SIP/2.0 403 Not relaying Via: SIP/2.0/UDP 172.16.220.1:5060 ;branch=z9hG4bK-11425-77062-0;rport=5060;received=10.1.11.197 From: sipp <sip:sipp@172.16.220.1:5060>;tag=11425SIPpTag0077062 To: sut <sip:service@10.1.1.197:5080 >;tag=b27e1a1d33761e85846fc98f5f3a7e58.489a Call-ID: 77062-11425(a)172.16.220.1 CSeq: 1 INVITE Server: kamailio (3.2.0 (x86_64/linux)) Content-Length: 0 '. 2012-03-22 08:55:43:933 1332377743.933965: Aborting call on unexpected message for Call-Id '77063-11425(a)172.16.220.1': while expecting '100' (index 1), received 'SIP/2.0 403 Not relaying Via: SIP/2.0/UDP 172.16.220.1:5060 ;branch=z9hG4bK-11425-77063-0;rport=5060;received=10.1.11.197 From: sipp <sip:sipp@172.16.220.1:5060>;tag=11425SIPpTag0077063 To: sut <sip:service@10.1.1.197:5080 >;tag=b27e1a1d33761e85846fc98f5f3a7e58.853f Call-ID: 77063-11425(a)172.16.220.1 CSeq: 1 INVITE Server: kamailio (3.2.0 (x86_64/linux)) Content-Length: 0 ********************************************************************* Thanks, Josh

Re: [SR-Users] ACCDB insert issues
by Yufei Tao 22 Mar '12

22 Mar '12

Hi I've also seen this error "ERROR: acc [acc.c:405]: failed to insert into database ". This seem to happen when cdrs_procedure runs at the same time of acc table insert. Can also be reliably reproduced by locking the acc table, make a call (about 20 seconds or more), end the call, wait for a short while, unlock acc table. This causes this error, and Kamailio inserts duplicated INIVTE / BYE entries into acc table. The number of duplicated entries depends on how long you've locked the table for. So I think this acc insert error may have been to do with table locking when cdrs_procedure is run. When there are duplicated entries in acc table, cdrs_procedure takes the first INVITE/BYE entires and updated the cdrs table correctly. But threw an error when it hits the next duplicated entry and stop. So for us it didn't seem to cause any trouble for cdrs records so I didn't chase it further. But would be nice if we could stop/handle the duplicated entries some how. Not a fix at at all, just some clues that might help.

Two things made the difference: 1. Use only the id as Pkey and remove all other indexes (helped a little). 2. Set myisam engine to the table (i knew that but tried innodb for its reliability) Now we are back in order to deal with many, many CAPS.

need help for newbie in Kamailio
by Rabary 21 Mar '12

21 Mar '12

Hi mailing, Newbie to kamailio, I follow this tuto http://nil.uniza.sk/sip/kamailio/adding-mysql-support-kamailio-31-debian-le… for the registration SIP via mysql database and it works fine, but I saw that when during the call we disconnect the called UAC from network or turn the power off the caller UAC don't hangup. Is there any tool for how to hangup call when the UAC on the other side has no network connection or it isn't power on durring a call ? I heard for mediaroxy or rtpproxy but I don't know if them can do what I except to haveand we also use ip routing to make kamailio server to communicate with the UAC so we don't use NAT. Our topology is: kamailio (with public IP address) ---> cisco switch ---> LAN ---> UAC (with private IP address) Thanks in advance. -- Inutile d'imprimer ce mail

Kamailio NP module
by Ahmed 21 Mar '12

21 Mar '12

Hi, I try to run this module, but unsuccesfully. Can you give me some advices? How I can start the pdb_server? I compile and install it, but don´t know how get it run. I must add loadmodule="pdb.so" in kamailio.cfg file? When I did it, kamailio didnt start. Starting end with error. I think that there missing bracket : # query external service for routing information if (!pdb_query("$rU", "$avp(i:82)")) $avp(i:82) = 0; # default routing } cr_route("$avp(i:82)", "$rd", "$rU", "$rU", "call_id"); Thank you for your answer. Have a nice day.

Request-URI in fail route
by Jan Klepal 20 Mar '12

20 Mar '12

Hello, I am trying to set simple no-answer forward scenario: Alice calls Bob and after timeout 5s forward to Carol (and additionally Carol timeout forward to Dave). I am using Kamailio 3.2.2 default config. There is part of routing logic for no-answer forwarding: route[RELAY] { if(is_method("INVITE")) { t_set_fr(5000); t_on_branch("BRANCH_ONE"); t_on_reply("REPLY_ONE"); t_on_failure("FAIL_ONE"); } if(!t_relay()) { sl_reply_error(); } } branch_route[BRANCH_ONE] { $avp(divert) = $null; if($rU == "bob") { $avp(divert) = "carol"; } # second problem if($rU == "carol") { $avp(divert) = "dave"; } } failure_route[FAIL_ONE] { if($avp(divert) != $null) { add_diversion("no-answer"); $rU = $avp(divert); route(LOOKUP); route(RELAY); } } First problem I encountered is that I can't check $rU in failure_route (it is always set to original Request-URI - bob). Is this normal behavior or am I missing something? Because of that I have to set divert destination in branch route. Second problem is when Carol's no-answer forward to Dave happens. Then add_diversion adds invalid diversion header because it uses Request-URI which is still set to bob. Kind Regards, Jan

FW: Unsuccessful call using DRouting - Request Timeout
by Fatima Chahrour~Vanrise Support 20 Mar '12

20 Mar '12

Dears, I started my lab on VMware (debian lenny) where I installed Kamailio 3.2 and started drouting configuration. I'm using 2 PCs each having an x-lite softphone and the Kamailio on the vmware all connected locally. My primary test is to make a call from x-lite on PC (192.168.111.11) to x-lite on PC (192.168.111.226) through Kamailio\ drouting modules (192.168.111.139). What is happening is that when I call 9611558800, for example, am getting 'Calling' message on PC x-lite followed by 'Call Failed: Request Timeout' after a certain time. Attached is my routing logic script, and ngrep for the call that is failing. And my dr_tables data is : dr_rules: 4, '0', '9611', '', 0, '', '#3', 'Lebanon Fix' dr_gw_lists: 3, '5', 'Test Call' dr_groups: 3, '.*', '.*', 0, 'Everyone' dr_gateways: 5, 1, '192.168.111.226', 0, '', '', 2, 'PC1' I tried adding port number to the gateways, remove '#' and add 5 in the dr_rules, remove the "0" from do_routing in the script, but with no success. Reading some related documents and books, I found that all scenarios using drouting have gateways as media servers (Asterisks) . So my question: is this a must, to have a media proxy even using my above primary enviroment? If not, can you please help me finding my mistake that prohibit the call's success(ringing)? Thanks in advance. F.Chahrour

Dispatcher and round-robin ignoring priorities?
by Øyvind Kolbu 20 Mar '12

20 Mar '12

Our PSTN provider has three servers. Two of them are located in our town, and we prefer them, and the last one much further away. We can use them interchangeably. >From our dispatcher file: # 10: PSTN 10 sip:preferred1.example.com:7476 0 5 10 sip:preferred2.example.com:7476 0 5 10 sip:third.example.com:7476 0 4 In our dispatch router we use 'ds_select_dst("10","4")'. Then the round-robin algorithm evenly distributes the load on all three of them, instead of round robin on the ones with priority 5 and fallbacking to priority 4. Is the unconditional round robin as excepted? When changing the selection algorithm to "8", «use first destination», the dispatcher module correctly uses first "preferred2", then "preferred1" and then lastly "third". Why «first destination» is not the first one listed in the dispatcher file has always puzzled me.. # kamailio -V version: kamailio 3.2.1 (i386/linux) 31c991 flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 31c991 compiled on 08:08:06 Dec 6 2011 with gcc 4.1.2 -- Øyvind Kolbu
