Kamailio 4.2.1 crashes on using exec_msg
by Tobias 13 Jan '15

13 Jan '15

Hi! We recently upgraded our Kamailio 4.1 to 4.2.1. With the newer version Kamailio crashes after just running a few minutes. After some debugging it looks as though the problem is in exec_msg (which is used in our config). After disabling this 4.2.1 seem to run just fine. Core file exists, here's the output: (gdb) backtrace #0 0x00000000005ebf0f in fm_extract_free (frag=0x7f053ea08d18, qm=0x7f053e88e010) at mem/f_malloc.c:206 #1 fm_malloc (qm=0x7f053e88e010, size=<optimized out>, file=file@entry=0x7f053cbedfd4 "exec: exec_hf.c", func=func@entry=0x7f053cbef378 "replace_env", line=line@entry=375) at mem/f_malloc.c:490 #2 0x00007f053cbe7953 in replace_env (list=0x7f053ea08868) at exec_hf.c:375 #3 0x00007f053cbe862e in set_env (msg=0x7f053e91d690) at exec_hf.c:547 #4 0x00007f053cbeb835 in w_exec_msg (msg=0x7f053e87c480, cmd=0x7f053ea5e168 "X֤>\005\177", foo=<optimized out>) at exec_mod.c:164 #5 0x00000000004274f7 in do_action (h=h@entry=0x7fff02e9cf90, a=a@entry=0x7f053ea5cfb8, msg=msg@entry=0x7f053e87c480) at action.c:1094 #6 0x00000000004261a9 in run_actions (h=h@entry=0x7fff02e9cf90, a=a@entry=0x7f053ea5cfb8, msg=msg@entry=0x7f053e87c480) at action.c:1583 #7 0x0000000000432980 in run_top_route (a=0x7f053ea5cfb8, msg=msg@entry=0x7f053e87c480, c=c@entry=0x0) at action.c:1669 #8 0x00007f053e610d2a in run_failure_handlers (t=t@entry=0x7f0534ecc770, rpl=0x7f053ea71040, code=486, extra_flags=extra_flags@entry=64) at t_reply.c:1051 #9 0x00007f053e612aa3 in t_should_relay_response (Trans=Trans@entry=0x7f0534ecc770, new_code=new_code@entry=486, branch=branch@entry=0, should_store=should_store@entry=0x7fff02e9d2a0, should_relay=should_relay@entry=0x7fff02e9d290, cancel_data=cancel_data@entry=0x7fff02e9d490, reply=reply@entry=0x7f053ea71040) at t_reply.c:1406 #10 0x00007f053e616126 in relay_reply (t=t@entry=0x7f0534ecc770, p_msg=p_msg@entry=0x7f053ea71040, branch=0, msg_status=msg_status@entry=486, cancel_data=cancel_data@entry=0x7fff02e9d490, do_put_on_wait=do_put_on_wait@entry=1) at t_reply.c:1809 #11 0x00007f053e61a9f3 in reply_received (p_msg=0x7f053ea71040) at t_reply.c:2493 #12 0x00000000004920a6 in do_forward_reply (msg=msg@entry=0x7f053ea71040, mode=mode@entry=0) at forward.c:783 #13 0x0000000000493637 in forward_reply (msg=msg@entry=0x7f053ea71040) at forward.c:885 #14 0x00000000004f5634 in receive_msg (buf=<optimized out>, len=<optimized out>, rcv_info=<optimized out>) at receive.c:275 #15 0x00000000005d929d in udp_rcv_loop () at udp_server.c:521 #16 0x00000000004a73f1 in main_loop () at main.c:1629 #17 0x0000000000425085 in main (argc=<optimized out>, argv=<optimized out>) at main.c:2561 Kind regards,/Tobias

Can you use the sr.modf() method / function to call append_branch?
by J Lee 08 Jan '15

08 Jan '15

I would like to know if there's a way to do parallel forking via lua code. So specifically, I'd like to be able to do something like this: seturi("sip:a@example.com"); append_branch("sip:b@example.com"); append_branch("sip:c@example.com"); append_branch("sip:d@example.com"); t_relay(); except via lua, because the list of branches is dynamic. I've tried the following: sr.modf("append_branch","sip:10.x.x.x") but the error message I'm getting is: /usr/sbin/kamailio[7437]: ERROR: app_lua [app_lua_sr.c:177]: lua_sr_modf(): function 'append_branch' is not available Just wondering if I "should" be able to do this. I've been reading http://www.kamailio.org/wiki/embeddedapi/devel/lua#srtm_package but haven't seen any references to append_branch. The other alternative I'm looking at is to just use lua to generate the list of destinations and pass back a hashtable of sorts to the cfg file. Then from there I will try to loop through the hashtable and do the append_branch command for each entry in the table. If you have other suggestions, I'd appreciate it. Thanks.

Kamailio Active / Active HA.
by Mahmoud Ramadan Ali 05 Jan '15

05 Jan '15

Hi Dears, I have successfully configured Kamailio HA using Heartbeat and Pacemaker so if one of the two servers should go down the other server will own the virtual IP address and take over. But i have two questions: 1.This model is considered to be Active / Passive redundancy so one server will process the SIP signaling until it goes down and i'm wondering is there is any way two achieve Active / Active redundancy and if so how the signaling will be handled on the servers so they can be aware of the transactions and dialogs traversing the servers ? does the signalling will be replicated or synchronized between the servers or what ?! 2.What about the servers DB and how they should be designed in a cluster mode ? i want to replicate all the DBs of the server to get consistent user registration using the subscriber table for example. Thanks in advance and Best regards.

presence - Error deleting subscription
by Jan Gaida 03 Jan '15

03 Jan '15

Hello, We are upgrading our servers to Kamailio 4.2 and we see a lot of error messages "Failed to delete subscription from memory". Scenario: This happens every time there is a Notify Timeout (408) and Kamailio tries to delete the subscription. Consequences: I don't know whether the delete fails because the entry did never exist, was already deleted or because the comparison (to_tag, callid or from_tag) is incorrect. It would be nice to at least have some details in the log message. I have not noticed any consequences to general functionality. I suspect the commit (74d73953327ad7702922b27ba37c71e3283659c3) to be responsible for this error because it introduced some extra checks on deletion. Does this happen to anybody else? What may be configured incorrectly on our system?

t_suspend()/t_continue() problem
by Dmytro Bogovych 02 Jan '15

02 Jan '15

Greetings. I'm trying to adopt kamailio to handle incoming calls / generate push notifications for softphone running on Windows Phone 8. Starting point was this publication http://www.kamailio.org/events/2014-KamailioWorld/day2/26-Daniel-Constantin… I adopted the script from publication a bit - now notification URI is extracted from REGISTER messages + INVITE transactions are not resuming when unregistering happens. However it does not work for me yet. I see the suspicious output in kamailio log when softphone registers after incoming push notification. Please ignore ERROR: level name - it is just dirty logging call, not real problem. Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: ERROR: <script>: resuming trasaction [40951:63820139] dbogovych (40951:63820139) Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: tm [t_lookup.c:1635]: t_lookup_ident(): DEBUG: t_lookup_ident: transaction found Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:181]: lookup(): contact for [dbogovych] found by address Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 90211984 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 91061218 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 91229062 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 90750343 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 87612750 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: DEBUG: registrar [lookup.c:327]: lookup(): instance is 91841578 Dec 17 14:20:11 voipobjects /usr/local/sbin/kamailio[29652]: WARNING: tm [t_lookup.c:1537]: t_unref(): WARNING: script writer didn't release transaction Can this "script writer didn't release transaction" be the problem?

Making media packets associated with calls appear unidirectional using rtpproxy and kamailio
by aft 31 Dec '14

31 Dec '14

Hi, I'm trying use two instances of rtpproxy listening to two different public IPs, to handle incoming and outgoing legs. That means i want to implement this network topology: SipClient--------->media from client to proxy--->rtpproxy1 Sipclient<----------media from proxy to client<---rtpproxy2 Where rtpproxy1 listening to IP1 and rtpproxy2 listening to IP2 in kamailio cfg : modparam("rtpproxy", "rtpproxy_sock", " udp:127.0.0.1:22222 udp: 127.0.0.1:22223") if (is_request()) { if (!has_totag()) { add_rr_param(";nat=yes"); } rtpproxy_offer("IP1"); } if (is_reply()) { if(isbflagset(FLB_NATB)) { fix_nated_contact(); } rtpproxy_answer("IP2"); } But its not working. Thanks in advance
