Re: [SR-Users] Kamailio Processes Stop Responding
by Peter DiSanto 05 Dec '16

OK thank you Alex. I will look into your suggestions next time the problem arises. Each call does generate one SQL LCR lookup, one CDR INSERT, and also a timer route that runs 3 queries every few minutes. Once Kamailio stops responding it will continue that way indefinitely until a process restart. Will report back. Thanks. Pete D

Restructuring source code tree for v5.0
by Daniel-Constantin Mierla 05 Dec '16

05 Dec '16

Hello, I already started playing with various scripts to do the restructuring of the source code tree for v5.0 as we discussed in the past months and I am considering to do it quite soon, in the next few days. The result will look like: /Makefile (only-forwarding make commands to various subdirs) /README|INSTAL|LICENSE|... /src/Makefile* (build makefiles) /src/main.c (main c file to generate the binary) /src/core/*.{c,h} (c code for core, including subfolders such as parser, mem, atomic, ...) /src/lib/* (subfolders with the internal libraries) /src/modules/* (subfolders with the modules) Other subfolders from root directory may be relocated, but to be decided along the way. At the time of doing the restructuring, I will try to merge all the pull requests that look ok. Therefore it would be good that anyone interested in open pull requests to do the review (and merge) meanwhile. Also, I think it would be good to disable travis and nightly master builds during few days when the restructuring happens in order to avoid flooding sr-dev with alerts. If anyone has suggestions to add, do not hesitate to write on mailing lists.

Rtpproxy settings without NAT in Kamailio
by shantanu saha 03 Dec '16

03 Dec '16

Hello, I am trying to configure rtpproxy with Kamailio. kamailio.cfg is already configured (default) for rtpproxy. I just add the following line at the top of the cfg file. *#!define WITH_NAT* After that rtpproxy is working in local network. Both client and sip server are running in local network. But when I run this in public network, rtpproxy didn't trigger. Rtppoxy and Kamailio are running in same public IP, Sip client also running in another *public IP. *So there is *no NAT* *.* Both local and public version was Centos 6 Kamailio version : 4.4 rtpproxy version: 2.1 Note: udp connection between rtpproxy and Kamailio was established (both in public and private network) Thanks shantanu saha

Dual Stack Environments

Hey all, Sorry for two questions out at the same time! I'm using kamailio in front of FS, and I'm about to enable IPv6, but I have a question that I'm not entirely clear on. What's the proper way to forward traffic using the same interface that it came in on? Specifically, if a client connects to kamailio on IPv6, it should connect to FS on IPv6, so that FS knows to advertise its v6 address in the SDP. The same should be true for v4. Is this possible? Best, Colin

In dialog messages cannot be routed after re-registration with outbound and gruu
by Robert 01 Dec '16

01 Dec '16

Hi, I'm using outbound with gruu enabled and with edge proxy, registrar and auth proxy all running as separate entities. My problem is once a dialog is formed between two UAs, if one side re-registers and gets assigned a new flow token, all subsequent in-dialog messages cannot be routed because the flow token in the Route set is no longer valid. What is the proper way to update the binding? I read in this thread <http://sip-router.1086192.n5.nabble.com/Outbound-and-Registrar-No-binding-u…> that "using GRUU means that Outbound is also used, so the Contact has a +sip.instance and reg-id params which are inspected by the registrar to create/update/delete a binding". How is the binding updated exactly? Any help would be appreciated. -- View this message in context: http://sip-router.1086192.n5.nabble.com/In-dialog-messages-cannot-be-routed… Sent from the Users mailing list archive at Nabble.com.

Kamailio Processes Stop Responding
by Peter DiSanto 30 Nov '16

30 Nov '16

We have a Kamailio 4.2 machine with a custom config file we've been using for the better part of two years without issue. Suddenly we've run into an issue where Kamailio just stops responding to any INVITEs, and stops any logging. The processes keep running but stop doing anything. It is a full production machine which naturally causes problems. I have the memlog from the restart after a hang if that helps, but I presume it is too large for this list. We have increased shared memory to 1536 and Pkg memory to 32 but that didn't help, and in any case the shmem stats look OK to us. It is a full production machine doing about 200 CPS, the load is barely measurable but turning logging to debug will surely kill it. We use TOPOH and do get lots of log entries like : /usr/sbin/kamailio[17865]: ERROR: <core> [parser/parse_via.c:2048]: parse_via(): ERROR: parse_via: bad char <▒> on state 100 /usr/sbin/kamailio[17865]: ERROR: <core> [parser/parse_via.c:2738]: parse_via(): ERROR: parse_via on: <▒#010d▒▒_▒#0117Jt▒#015#012X> /usr/sbin/kamailio[17865]: ERROR: <core> [parser/parse_via.c:2744]: parse_via(): ERROR: parse_via: via parse error /usr/sbin/kamailio[17865]: ERROR: topoh [th_msg.c:438]: th_unmask_via(): cannot find cookie in via2 /usr/sbin/kamailio[17865]: ERROR: topoh [th_mask.c:165]: th_mask_decode(): invalid input string"642525435_130081688(a)xxx.xxx.xxx.xxx" /usr/sbin/kamailio[17865]: ERROR: topoh [th_msg.c:484]: th_unmask_callid(): cannot decode callid and CRITICAL: sl [../../forward.h:279]: msg_send(): unknown proto 0 However, I believe these are not new and do not seem to affect overall call processing.

Offload SSL from backends with Kamailio
by Vladyslav Zakhozhai 30 Nov '16

30 Nov '16

Hi, I'm trying to understand the best (or reasonable) approach of offloading SSL encryption from backend to Kamailio. Let me simplify a little bit: UAC == SIP/TLS ==> Kamailio == SIP/UDP ==> FreeSWITCH My main problem is in Contact header of SIP packet which passes through Kamailio SIP proxy and remains unmodified. For example, REGISTER request. There is FreeSWITCH backend which is registrar server as well. UAC send REGISTER request to it through Kamailio SIP proxy via SIP/TLS. This request dispatches to backend(s) by Kamailio with dispatcher module. Backend does not configured to support TLS. In this case everything works fine: I see REGISTER requests on FreeSWITCH. But Contact header of SIP message which is passing Kamailio remains unmodified. And as result I see on FreeSWITCH something like the following: Call-ID: Jpmjp4ruHI User: user_name@domain_name Contact: "" <sip:user_name@uac_ip :27026;transport=tls;fs_path=sip%3Akamailio_ip%3A5060> Agent: Linphone/3.10.2 (belle-sip/1.5.0) Status: Registered(TLS)(unknown) EXP(2016-11-28 11:48:28) EXPSECS(110) Ping-Status: Reachable Ping-Time: 0.00 Host: kamailio_host IP: kamailio_ip Port: 5060 Auth-User: unknown Auth-Realm: domain_name MWI-Account: user_name@domain_name As a result FreeSWITCH tries to originate call over SIP/TLS and it fails because FreeSWITCH does not configured to work with TLS. I want to understand what is correct workaraound of this issue. Do I need to modify Contact header manually on kamailio host and this is right approach? Or kamailio in case of correct config rewrites this header itself? If parts of my kamailio config would be useful I will post it later. Thanks in advance. -- С уважением, Владислав Захожай

Re: [SR-Users] Kamailio IMS virtual machine

Hi Rafael, There should not be a problem with the VMware mage. Regarding your question: you have to check kamailio-pcscf.cfg to recognize when and it how forward the SIP message towards the I-CSCF. I guess it is the statement "t_relay();" in line 896. You may provide a core tracefile (generated with tcpdump), then I may have aquick look ate your ise.

Problems with Siremis and Kamailio - PHP7
by Diogenes Aviles 29 Nov '16

29 Nov '16

I have Kamailio 4.4 installed in ubuntu 16.04.03, with Siremis 4.2.0, PHP7 and apache2. All is OK, but when I try to install the Siremis Wizard, the step 2 (Data Base Configuration) doesn't work, and there is the message "Something Went Wrong". I tried all the option on Step 2, but the problem continuous. Then I can't go to step 3 Application Configuration. The Siremis DataBase is created and the user also. I appreciate any help. -- Diogenes

custom version database/table
by David Villasmil 28 Nov '16

28 Nov '16

Hello all, I have a databse where i created a "version" table only with a version, a dispatcher records. I only want to use dispatcher on a db. I don't know if kamailio is looking for the version tables somewhere else, or it does find it in my database (not named kamailio) but the format is wrong. I used: CREATE TABLE `version` ( `table_name` VARCHAR(32) NOT NULL, `table_version` INT UNSIGNED DEFAULT 0 NOT NULL, CONSTRAINT table_name_idx UNIQUE (`table_name`) ); INSERT INTO version (table_name, table_version) values ('version','1'); INSERT INTO version (table_name, table_version) values ('dispatcher','4'); To create an populate the table, but kamailio returns: mod_init(): could not initiate a connect to the database but it does connect properly... any thoughts?

Recent problem with fix_nated_sdp and kamailio 4.4.4
by Anthony Messina 28 Nov '16

28 Nov '16

Prior to the upgrade to Kamailio 4.4.4, I was using 4.4.3 with updates through 81df84b from the 4.4 branch and the following fix_nated_sdp call worked through the initial INVITE and when a voicemail branch was appended from the failure_route. route[NATMANAGE] { ... # RTPEngine is not needed but if STUN addresses are being used on our # internal network, rewrite the addresses to the internal source address if(!isbflagset(FLB_RTPENGINE) && has_body("application/sdp")) { if(dst_ip==10.1.1.2 && compare_pure_ips($sel(contact.uri.host), "<EXTERNAL_IP>")) { fix_nated_sdp("10"); } } ... } Since the upgrade to 4.4.4, when the original INVITE fails over to voicemail (branch appended), fix_nated_sdp creates the SDP below, doubling the replaced IP addresses. Asterisk replies with 488, as the media address is completely invalid. I need something like the above (which worked for the request and the reply) but can't figure out what the problem is. v=0 o=Zoiper 0 0 IN IP4 10.1.1.18210.1.1.182 s=Zoiper c=IN IP4 10.1.1.18210.1.1.182 t=0 0 m=audio 63732 RTP/SAVP 9 3 0 97 101 a=rtpmap:9 G722/8000 a=rtpmap:3 GSM/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:97 iLBC/8000 a=fmtp:97 mode=30 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=sendrecv a=crypto:5 AES_256_CM_HMAC_SHA1_80 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDIGKI2LPOLdNDOcpFdtqu5DQ== a=crypto:6 AES_256_CM_HMAC_SHA1_32 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDIGKI2LPOLdNDOcpFdtqu5DQ== a=crypto:3 AES_192_CM_HMAC_SHA1_80 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDIGKI2LPOLdNA= a=crypto:4 AES_192_CM_HMAC_SHA1_32 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDIGKI2LPOLdNA= a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDI a=crypto:2 AES_CM_128_HMAC_SHA1_32 inline:n2C0BcdXOr32BPTEE8pfHII9mamAK566xMNvQIDI a=oldmediaip:<EXTERNAL_IP> a=oldmediaip:<EXTERNAL_IP> a=oldmediaip:<EXTERNAL_IP> a=oldmediaip:<EXTERNAL_IP> -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery F9B6 560E 68EA 037D 8C3D D1C9 FF31 3BDB D9D8 99B6

kamailio core dumps once every few days
by davy van de moere 28 Nov '16

28 Nov '16

Gents, On a not really loaded kamailio (less than 50 users at the moment), I'm getting a core dump every few days. I've tried multiple verisons of Kamailio, 4.4.x , 4.3.x and also on 5.0.0-dev7 . I can't reproduce it adhoc, but every few days it happens...

Balancer with Dispacther Module
by Rodrigo Moreira 28 Nov '16

28 Nov '16

I need help. I'm building a load balancer using the dispatcher. It does NAT with too many SIP Servers. But when the balancer receives an ACK from UAC, it immediately returns the message "404 Not Here" to UAC. Help me solve this, since this message (ACK) has to be forwarded to SIP Servers and finally to UAS to start an RTP session. I thank you. Att., -- Rodrigo M.
