by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#424 - zombie dialogs in state 5 User who did this - Ovidiu Sas (osas) ---------- It is the dialog:end route, so it cannot be executed inside dlg_manage(). Here are the logs with all the functions that are called during BYE processing: - has_totag() - loose_route() - if (is_method("INVITE")) { - t_relay() <code> Sep 23 11:11:36 centos k[1053]: ERROR: ***

[tracker] Task opened: CANCEL sent shortly after '100 trying' response to INVITE does not always end the call (Attachment added)

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Sławomir Bocheński (lkslawek) Attached to Project - sip-router Summary - CANCEL sent shortly after '100 trying' response to INVITE does not always end the call Task Type - Bug Report Category - Core Status - Unconfirmed Assigned To - Operating System - Linux Severity - Low Priority - Normal Reported Version - 4.1 Due in Version - Undecided Due Date - Undecided Details - This is the situation we have observed during some manual tests of SIP-enabled product when using Kamailio as registrar and proxy. When a client sends INVITE via Kamailio and then right after receiving '100 trying' provisional response it sends CANCEL, it happens that Kamailio replies instantly with '487 terminated' and yet it continues to forward the INVITE to the callee's end. So to put this in diagram: <code>caller kamailio callee | | | |---------- INVITE -------->| | |<------- 100 trying -------| | |---------- CANCEL -------->| | |<-- 487 Request canceled --| | |<--- 200 ok -- no more ----| | | pending branches | | | |---------- INVITE -------->| |---------- ACK ----------->| | | |<------- 180 Ringing ------|</code> It seems to me that another Kamailio process is processing the CANCEL before INVITE has been fully processed and it is yet unaware of the session existence. The problem was originally observed on our Kamailio 4.0 instance with the routing script based on the default one, with NAT and authorisation enabled. Actually enabling NAT is one of the factors that makes this to occur more frequently, as anything that slows down INVITE processing. Even enabling debugging makes the probability rise. For simulation it's enough to e.g. insert sleep(1) at the top of the NATMANAGE block. I've also confirmed this on the latest release, that is 4.1.6, and on git master branch. Attached logs were collected while using Kamailio development version compiled from git tree, branch master, using the default ./etc/kamailio.cfg modified to have full debug in syslog only, so defining WITH_DEBUG and setting log_stderr to 'no'. No other changes. Logs start with series of successful cancels, followed by one occurrence of the problem. Both ends are running baresip 0.4.11. Callee is using TCP transport, listening on 5061 (but no TLS, so you may tune your dissector to decode 5061 as SIP), caller - UDP. Note that using UDP on both ends only slightly changes the reply sent on CANCEL, but the problem stays. The tests for logs were mostly performed using caller's baresip with enabled module cons.so, thus accepting command over tcp port 5555, by running some flavour of: <code>( echo -e 'dcallee'; sleep 0.01; echo -ne '\e' ) | nc localhost 5555</code> In baresip console this is d for dial, destination and <RET> to confirm, then <ESC> to cancel/drop the call. Pasting 'dcalle\n\e' sequence from the X selection buffer directly to baresip console even without delay before cancellation also should do (although baresip more or less often will cancel the call before actually sending the INVITE itself). One or more files have been attached.

rtpengine - Unknown flag encountered: 'force'

by Muhammad Shahzad

Hi, I upgraded both kamailio and RTPEngine to latest trunk last night and now when I engage media proxy for any call i see following warning in rtpengine logs, rtpengine[8506]: Unknown flag encountered: 'force' The list of flags i pass in offer is, 'force trust-address replace-origin replace-session-connection ICE=remove' Although i am not running chain of rtp proxies, so it is probably safe for me to remove this flag but still this may be a bug in RTPEngine. The flag is listed in kamailio's rtpengine module documentation here, http://kamailio.org/docs/modules/devel/modules/rtpengine.html#rtpengine.f.r… Thank you.

Reqd. help on Corex (Obfuscate) - Kamailio 4.2.x

by Rahul MathuR

Hello, I was going through the new features and stumbled upon this new one - developed by Mohd. Shahzad Shafi. As already mentioned on the wiki about this module, I intend to use it for my custom security layer between UACs and SIP Proxy (Kamailio) but the issue is - the custom security layer (encryption/decryption code) is written in C and should precisely be applied for the messages between UAC and Proxy. Is there a way I can achieve this using Corex module since it does intercept the network I/O messages ? Any help here would be really appreciated. -- Warm Regds. MathuRahul

Re: [sr-dev] sr-dev Digest, Vol 71, Issue 70

by varun pratapsingh

HI Shehzad, First of all thanks to you for writing such a nice module. I am also facing the same problem. The module works fine when UAC (PJSIP) sends the encoded SIP packet on UDP transport but when it sends the same encoded packet with TCP transport it never reaches to the nio_msg_received() function in corex_nio.c and so does not print anything in $mb when printed from the kamailio.cfg using the xlog in event_route[network:msg]. Digging further I also found that when kamailio receives the TCP packet with encoded sip in file tcp_read.c in function tcp_read_headers() then it goes for some tcp_headers parsing and drops the packet. But it works good when the TCP packet data segment is not encoded that is SIP packet is not encoded and transmitted on TCP : 1) TCP Headers + payload (SIP Packet) ----> this case works fine 2) TCP Headers + payload (encoded SIP Packet) ------> this case does not work fine. Any pointers where I might be wrong.
