Not getting correct result after sending a OPTION query

Hi, I'm trying to understand intricacies of SIP protocol. I'm installed a stock kamailio from git repo. kamcmd> core.version kamailio 4.0.2 (x86_64/linux) f87866 Now i'm trying to send OPTION request by "sipsak". I've added two users : arif@khost:~$ kamctl db show user ........... +----+----------+---------------+------------+---------------+----------------------------------+----------------------------------+------+ | id | username | domain | password | email_address | ha1 | ha1b | rpid | +----+----------+---------------+------------+---------------+----------------------------------+----------------------------------+------+ | 1 | test | 192.168.7.143 | testpasswd | | ad87b307789553f95799738d87246ca0 | e211f539e22a1ad2cc0f3c07056c3517 | NULL | | 2 | test2 | localhost | testpasswd | | 46d8618f5b652e4aeff3ffe52f373028 | bb8564b436dcfa183a8228244d8527ea | NULL | +----+----------+---------------+------------+---------------+----------------------------------+----------------------------------+------+ Now The OPTION message i'm trying : OPTIONS sip:test_local@localhost SIP/2.0 Via: SIP/2.0/UDP 127.0.1.1:60518;branch=z9hG4bK.374c1583;rport;alias From: sip:sipsak-jEV4NMQqubUqMp+WYRx65w@public.gmane.org:60518;tag=74766f41 To: sip:test_local@localhost Call-ID: 1953918785-jEV4NMQqubUqMp+WYRx65w(a)public.gmane.org CSeq: 1 OPTIONS Contact: sip:sipsak-jEV4NMQqubUqMp+WYRx65w@public.gmane.org:60518 Content-Length: 0 Max-Forwards: 70 User-Agent: sipsak 0.9.6 Accept: text/plain kamailio is respoding with : SIP/2.0 404 Not Found After digging in kamailio log : 2(17356) DEBUG: registrar [lookup.c:158]: lookup(): 'test_local' Not found in usrloc -- The code reads : 155 ul.lock_udomain(_d, &aor); 156 res = ul.get_urecord(_d, &aor, &r); 157 if (res > 0) { 158 LM_DBG("'%.*s' Not found in usrloc\n", aor.len, ZSW( aor.s)); So it seems i'm doing something very wrong. Although in my config : 106 #!define WITH_MYSQL 107 #!define WITH_AUTH 108 #!define WITH_USERLOCDB After going through the RFC3261's section 11.2, It seems this OPTION message should work and generate a 200(OK). What it is i'm doing wrong? -- -Cheers -Arif

Regarding Instant messaging using TCP on Kamailio 3.3
by Sunil Chandrasekharan 20 Jun '13

20 Jun '13

Hi All, I have set up Kamailio 3.3 on Ubuntu machine.I created two user test 1 and test 2. I could use Presence and also i was able to register to Kamailio server and exchange presence status with each other. Details- I used TCP protocol . testing methods - Linphone, a sample application. I am able to register succesfully with (TCP) on to kamailio server using Lin phone and sample application. I am able to update presence status of the users. Issue : When i try to send messages between two users ( using TCP ) 1. from Sample application, when i try to send message, i get 420 temporarily Unavailable error from server. 2. from Lin phone 3.5.2, i was able to send messages ( sue TCP) but when the other user try to reply back , i get same error 480 Temporarily Unavailable. error from server. I want a support to understand why i get error while sending messages with TCP via Kamailio server. I am able to succeesfully send and receive messages when i use UDP from my sample application and Lin phone. regards Sunil C

Hi all, I am trying to install the latest version using git (new to git) and after running "git checkout -b 4.0 origin/4.0" I got these messages: [root@test kamailio-4.0.2]# git checkout -b 4.0 origin/4.0 fatal: Cannot update paths and switch to branch '4.0' at the same time. Did you intend to checkout 'origin/4.0' which can not be resolved as commit? [root@test kamailio-4.0.2]# These were the commands I entered in order: [root@test kamailio-4.0.2]# mkdir -p /usr/local/src/kamailio-4.0.2 [root@test kamailio-4.0.2]# cd /usr/local/src/kamailio-4.0.2/ [root@test kamailio-4.0.2]# git clone --depth 1 git://git.sip-router.org/sip-router kamailio [root@test kamailio-4.0.2]# cd kamailio [root@test kamailio-4.0.2]# git checkout -b 4.0 origin/4.0 --> this is were it fails What does it mean, how should I proceed?

Dispatcher behaviour
by Mino Haluz 19 Jun '13

19 Jun '13

Hi, I've been playing with dispatcher settings, and I cannot get it working as expected. I would like to have my destination IP1 being always probed and some destinations should be marked as active non-probing. So, in my config I have ds_probing_mode = 0 (documentation: If set to 0, only the gateways with state PROBING are tested;) Ok, so I set flag = 8 in dispatcher list for IP1 (documentation: 3 (value 8) - probing destination (sending keep alives);) Restart of kamailio, host IP1 is AP, after first interval (10sec), 200OK from gateway is received, and host becomes AX (active non-probing). Why ?? What I expect is that host stays AP. Why the probing mode is turned off when first check is OK? I can somehow do it with ds_probing_mode = 1 but this is not I want - I need that some gateways are not probed at all (documentation: if set to 1, all gateways are tested - useless for me) I tried every flag range 0-10. I think it does not work as documentation states or I simply do not understand its meaning. Please help me to have this clear, this module is quite critical for us. Thanks, Mino

Fwd: Call breaks after 32 seconds
by Martin Moučka 19 Jun '13

19 Jun '13

Hello, we have problem here with outbound calls. Many devices for example Zyxel, WELL 8820IP, Interbell and some software clients Ekiga v3.3.2 and SJ Phone drops call after 32 seconds. I think it could be some new standard from 2007, because Ekiga v4.0 seems ok and mentioned hardware devices don't have new firmware since this year. Can you confirm that please? I'm attaching some captures. Thank you

bug in 4.0.2 dialog module, no keep alives when src==dst
by Daniel Tryba 19 Jun '13

19 Jun '13

Trying to implement calllimits with the dialog module I can reproduce a hanging dialog using a Linksys 962 by calling itself. When trying to answer the call the INVITES end in a 200 OK but the call is terminated [linksys.txt]. That might be a bug in the 962, but the bad part is the dialog will be kept in kamailio even though keep alives are enabled. OPTIONS are not being sent to detect this dead dialog. If this devices calls an other device (either registered to this kamailio or to the PSTN) KA work like configured (they are being send to this device). Severing the connection will be detected and the dialog will be removed. But when source and destination is the same device, no OPTIONS are sent. About 1 hour later the dialog is still there: # kamctl mi dlg_list dialog:: hash=3456:6742 state:: 3 ref_count:: 2 timestart:: 1371572203 timeout:: 68536211 callid:: 86a23723-4b71d5ad@localhost from_uri:: sip:anonymous@localhost from_tag:: 1736b8ab3ea801c5o0 caller_contact:: sip:+31880100781@10.0.34.226:17852 caller_cseq:: 102 caller_route_set:: caller_bind_addr:: udp:10.0.32.42:5060 callee_bind_addr:: udp:10.0.32.42:5060 to_uri:: sip:0880100781@10.0.32.42 to_tag:: 195218c1d50330b5i0 callee_contact:: sip:+31880100781@10.0.34.226:17852 callee_cseq:: 102 callee_route_set:: A part of syslog with debug=4 for above dialog is attached (not the same dialog as the attached linksys capture).
