Question about Proxy-Authorization header in ACK
by Ivan Milivojevic 06 Aug '12

06 Aug '12

Hi all, I have a one question regarding ACK and Proxy-Authorization header. I am testing Kamailio 3.3 as SIP proxy,default config. I made one call with 2 phones where one has Public IP while other is behind NAT. SIP clients are Panasonic KX-UT133 and other is 1-NET (ex Sweden Mobile&CDMA provider ,over 50M users) Everything is working just fine, both RTP and SIP. On the other hand one of the clients,1-NET one, send Proxy-Authorization in ACK when he receives 200 OK from Kamailio. PUBLIC_IP_USER1 - user 1000 PUBLIC_IP_USER2 - user 1001 KAMAILIO ==> 1-NET SIP/2.0 200 OKr\n Record-Route: <sip: <sip:KAMAILIO_PUBLIC_IP;lr=on;nat=yes> KAMAILIO_PUBLIC_IP;lr=on;nat=yes> Via: SIP/2.0/UDP PUBLIC_IP_USER1:5064;rport=5064;branch=z9hG4bK934894606 Call-ID: 221374358 From: blabla <sip:1000@ <sip:1000@KAMAILIO_PUBLIC_IP> KAMAILIO_PUBLIC_IP>;tag=507511069 To: <sip:1001@ <sip:1001@KAMAILIO_PUBLIC_IP:5060> KAMAILIO_PUBLIC_IP:5060>;tag=2148378512 CSeq: 21 INVITE Allow: INVITE,ACK,CANCEL,BYE,INFO,UPDATE,OPTIONS,NOTIFY,REFER Contact: <sip:1001@ <sip:1001@PUBLIC_IP_USER2:1027> PUBLIC_IP_USER2:1027> Require: replaces Content-Type: application/sdp Server: Panasonic_KX-UT133NE/01.081 (0080f0cedd83) Content-Length: 182 v=0 o=- 1343736535 1343736535 IN IP4 KAMAILIO_PUBLIC_IP s=- c=IN IP4 KAMAILIO_PUBLIC_IP t=0 0 m=audio 20412 RTP/AVP 18 a=rtpmap:18 G729/8000 a=sendrecv a=ptime:20 a=nortpproxy:yes 1-NET ==> KAMAILIO ACK sip:1001@ <sip:1001@PUBLIC_IP_USER2:1027> PUBLIC_IP_USER2:1027 SIP/2.0 Via: SIP/2.0/UDP PUBLIC_IP_USER1:5064;rport;branch=z9hG4bK642028490 Route: <sip: <sip:KAMAILIO_PUBLIC_IP;lr=on;nat=yes> KAMAILIO_PUBLIC_IP;lr=on;nat=yes> From: blabla <sip:1000@ <sip:1000@KAMAILIO_PUBLIC_IP> KAMAILIO_PUBLIC_IP>;tag=507511069 To: <sip:1001@ <sip:1001@KAMAILIO_PUBLIC_IP:5060> KAMAILIO_PUBLIC_IP:5060>;tag=2148378512 Call-ID: 221374358 CSeq: 21 ACK Contact: <sip:1000@ <sip:1000@PUBLIC_IP_USER1:5064> PUBLIC_IP_USER1:5064> [truncated] Proxy-Authorization: Digest username="1000", realm="KAMAILIO_PUBLIC_IP", nonce="UBfL8lAXysb5tJCs80ZnthyPl9IzmRZk", uri="sip:1001@KAMAILIO_PUBLIC_IP:5060", response="7824519cdad9f1c2c79027a2d7522344", algorithm=MD5, cnonce="0a4f113b", q Max-Forwards: 70 User-Agent: Serbia_2.00 Content-Length: 0 I attach txt file with call flow, I can send pcap also.

REGISTER replication to multiple hosts
by Henning Holtschneider 06 Aug '12

06 Aug '12

Hello, I'm trying to migrate an existing configuration from OpenSIPS 1.4.x to Kamailio 3.2.x. The old configuration replicates REGISTER requests to multiple servers using this code in the REGISTER routing block: add_sock_hdr("Local-Sock"); add_rcv_param(); append_branch("sip:1.1.1.1:5060"); t_replicate("sip:2.2.2.2:5060"); exit; From what I read in the documentation, the behaviour of append_branch() is different in Kamailio, so I modified my code like this: add_sock_hdr("Local-Sock"); add_rcv_param(); append_branch(); seturi(sip:1.1.1.1:5060"); t_replicate("sip:2.2.2.2:5060"); exit; Unfortunately, I do not see any REGISTER requests arriving on 1.1.1.1 so I assume that I made a mistake when forking the request. Can anyone point me in the right direction?

Getting started with Kamailio
by Markus 05 Aug '12

05 Aug '12

Hello! I'm new to this list and Kamailio. First, thanks to all the programmers that developed this software. I'd like to ask several questions on how to get started with Kamailio and the basic understanding of it. I'm trying to figure out Kamailio only since yesterday. Right now I have a single Asterisk server that handles signaling and media. For accounting and user administration I'm using a2billing with MySQL on it. For redundancy and scalability I would like to create the following setup: France: BGP anycast 195.5.5.0/24 2 nodes with Kamailio (IP 195.5.5.5) active + standby 2 nodes with Asterisk + a2billing + DRBD for active-active MySQL cluster. Spain: BGP anycast 195.5.5.0/24 2 nodes with Kamailio (IP 195.5.5.5) active + standby 2 nodes with Asterisk + a2billing + DRBD for active-active MySQL cluster. (a2billing MySQL DB will be always synchronous over all nodes in Spain and France) This will give me: - Network redundancy (data center burns down in France, I stay online in Spain). This will be handled by BGP anycast. - Signaling redundancy (Kamailio active + standby). This will be handled by Linux-HA or something like that. - Media redundancy (2x Asterisk per country). This will be handled by Kamailio dispatcher. - Application/database redundancy (2x a2billing per country + synchronous MySQL DB everyhwere). This will be handled by DRBD and MySQL. = High redundancy, I can sleep and it can scale. What I would like to achieve besides the above: - Give only a single IP address to all customers and termination providers (the same IP address), 195.5.5.5. I'm a SIP noob, so I have to ask: - How do I do the Kamailio part? ;-) ... I have seen this how-to for Kamailio/Asterisk realtime: http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb But it feels like "overkill". If I would not have any users that actually REGISTER (e.g. in a pure wholesale termination environment), I would not need Kamailio/Asterisk realtime integration. Correct? - Is there no way around changing the Asterisk side (activating realtime, new MySQL DB) when I have users that do need to REGISTER? If I would not be using a2billing I could probably handle all the registrations in Kamailio only? - Since Kamailio and Asterisk will not be on the same box, what is the recommended way for Kamailio securely communicating with the MySQL database on the Asterisk server? Does Kamailio support SSL with MySQL? - If I use RTPproxy on the Kamailio server, every customer and termination provider would connect to 1 single IP address, because both media and signaling comes from that IP. Correct? - If I don't use RTPproxy, and have canreinvite=yes on my Asterisk servers, customers would get the media, when placing PSTN calls, directly from my termination providers (I would like to avoid that). Correct? - If I don't use RTPproxy, and have canreinvite=no on my Asterisk servers, customers will get the media directly from my Asterisk servers, but termination providers that filter based on IP addresses they would have to allow all Asterisk IP addresses in their filters (same for customers, actually). Correct? Right now I didn't have to worry about such things because media and signaling were handled by a single Asterisk box with canreinvite=no everywhere. - Last question for now: why does it seem like important developers of SIP software such as Kamailio and yate are originating from Romania and are female? Just a coincidence? :-) Regards Markus

302 redirect with 2 numbers registered
by Mino Haluz 03 Aug '12

03 Aug '12

Hi, one number is registered on 2 phones. Phone1 has Always redirect set to another number. When incoming call is initiated, Phone2 is ringing and Phone1 sends 302 to the proxy. However the proxy does not send 302 to the caller (for ex. GW), but it waits for timeout of the Phone2. Then the proxy sends 302 to the caller. Can I do in kamailio, that it will ring on the Phone1 and also on the number where it is redirected? I know kamailio is a proxy and cannot initiate a call, but is there any solution? Thanks. Mino

Outbound and Registrar. No binding update
by José Luis Millán 02 Aug '12

02 Aug '12

Hi, I'm using Kamilio 3.3.0 as registrar server. I`m using an outbound proxy so 'use_path' parameter or 'registrar' module is enabled. According to RFC 5626, a re-registration from a specific combination of AoR, instance_id and reg_id must update the binding. "" If the registrar receives a re-registration for a specific combination of AOR, and instance-id and reg-id values, the registrar MUST update any information that uniquely identifies the network flow over which the request arrived if that information has changed, and SHOULD update the time the binding was last updated. "" In my installation this is not fullfilled as shown: "" AOR:: jmillan Contact:: sip:jmillan@MY_IP;transport=ws;ov-ob=a570655c14 Q= Expires:: 181 Callid:: 1hgq3khalq2rzfr Cseq:: 108 User-agent:: JsSIP 0.1.0 Path:: <sip:OUTBOUND_IP:9090;transport=tcp;lr;ovid=de0c0b9f>,<sip:a570655c14@OUTBOUND_IP :10080;transport=ws;lr;ovid=de0c0b9f;ob> State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: tcp:KAM_IP:5060 Methods:: 783 Ruid:: uloc-50119d99-328e-1 Instance:: <urn:uuid:38dce009-ae1f-4fd1-91dc-99ed9affddc1> Reg-Id:: 1 Contact:: sip:jmillan@MY_IP;transport=ws;ov-ob=1dd97b4d51 Q= Expires:: 193 Callid:: 1hgq3khalq2rzfr Cseq:: 110 User-agent:: JsSIP 0.1.0 Path:: <sip:OUTBOUND_IP:9090;transport=tcp;lr;ovid=de0c0b9f>,<sip:1dd97b4d51@OUTBOUND_IP :10080;transport=ws;lr;ovid=de0c0b9f;ob> State:: CS_SYNC Flags:: 0 Cflag:: 0 Socket:: tcp:KAM_IP:5060 Methods:: 783 Ruid:: uloc-50119d99-3290-2 Instance:: <urn:uuid:38dce009-ae1f-4fd1-91dc-99ed9affddc1> Reg-Id:: 1 "" The scenario is such that when the client looses the connection with the Outbound Server, it reconnects and re-registers to Kamailio in order to replace registration and be able to receive in-dialog messages. Any comment is wellcome. Regards,

by Alex Solt 01 Aug '12

01 Aug '12

Hi, We are getting "cannot allocate memory" error in the log file. I was wondering which one is the right way to increase the shared memory: 1) adding the following to /etc/openser/openserctl STARTOPTIONS="-m 128" 2) modify the following in /etc/default/openser MEMORY=1024 Thanks,AS

routing based on username
by Richard Zheng 31 Jul '12

31 Jul '12

Hi, We are trying to follow http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdbto setup Kamailio as front end and multiple PBXs as back end. We need to forward sip messages to the respective servers based on the contact. For example, users 101, 102 go to PBX at 1.1.1.1 and users 201, 202 go to PBX at 1.1.1.2. Where is a good place to save this info and how to route them in the config? Also we have some users with fixed IP addresses which don't use authentication. How do we route the calls based on source IP? Since we have plenty of these users, we'd like to save them in database too. Any advice is appreciated! Richard

BYE Race Condition
by Brandon Armstead 31 Jul '12

31 Jul '12

Hello, I am running into an issue where there is a race condition happening. I am looking for opinions / ideas on how to handle the following below scenario. Scenario. UAC places an outbound call -> upstream carrier. The call is disconnected on both ends at the exact same time, UAC -> sends BYE upstream Upstream Carrier -> sends BYE downstream Upstream 200 OK's the BYE UAC sends 481 back to Upstream Carrier for their generated BYE. The upstream carrier is complaining about receiving the relayed 481 responses -- so my first thought was simply to drop() these from relaying upstream. I am curious how other people are handling this? Would you suggest simply dropping the relay from being sent back upstream on the 481? Would you simply always 200 OK a downstream BYE from trusted carriers regardless of UAC response, and create separate transaction to send BYE downstream? Thank you as always. Look forward to your thoughts / suggestions / ideas. Sincerely, Brandon Armstead

Re: [SR-Users] Kamailio with APNS
by Duong Manh Truong 29 Jul '12

29 Jul '12

Thank Klaus, I've try with t_suspend() and t_continue() as your guide, *#Failure route to react with negative messages failure_route[1] { if (t_check_status("5[0-9][2-9]")) { if(t_suspend()) { xlog("proceesing suspended in trasaction [$T(id_index):$T(id_label)]\n"); xlog("before sleep \n"); } if(async_sleep("20")) xlog("After sleep 20s \n"); if(t_continue('1','1','MYROUTE')) xlog("Continuation successfully \n"); exit; };* And i found that t_suspend() and async_sleep() runnung ok but t_continue() seems not running. I read about TMX module and TMX module Pseudo-Variables but still can not figure out it :( Secondly, in case of t_continue() runs successfully , please tell me how to let Kamailio resend the INVITE message to client B (before the t_continue(), i think so ) - while client B is waking up ? Which functions and modules that i need to do this? Thanks. ----------------------------------------------------------------- Hi! You have to use a failure route (http://kamailio.org/docs/modules/3.3.x/modules/tm.html#t_on_failure). In the failure route check if the reply code is 404 and if yes, trigger the APNS logic and then put the call e.g. on a stack and resume e.g. every second and ofrward to the "SIP server" again to see if the client is registered meanwhile. For the asynchronous processing take a look at these functions: t_suspend(),t_resume()[1]. For example you can call t_resume in a timer route every second. For the timer route, to know which transactions are currently suspended and are waiting for further processing, you could put the transaction identifiers in a message-queue [2] and read the queue from the timer route. regards Klaus [1] http://kamailio.org/docs/modules/3.3.x/modules_k/tmx.html#id2535968 [2] http://kamailio.org/docs/modules/3.3.x/modules/mqueue.html On 24.07.2012 06:02, Duong Manh Truong wrote: >* Hi list,*>**>* My team are developing a SIP client for mobile running iOS ,*>**>* then having to deal with the "back ground mode" problem while this soft*>* is installed on mobiles*>**>* One of the solutions is using APNS.

Add CallerID to SIP header
by Dominic Raferd 27 Jul '12

27 Jul '12

I'm not yet using Kamailio. I am looking for something to do a job which sounds really simple but may not be. Our PBX connects to a SIP service (voicetrading.com) but does not supply our CallerID, this means that voicetrading.com provide some very weird callerids for the person at the other end (international numbers etc). Which is not good. There is no way to get our PBX to add CallerID itself, so I thought maybe I could set up a local sip proxy? or sip redirect? server (Kamailio?) to do nothing other than add in the callerid details to the sip header and then forward the sip message on to voicetrading i.e. be otherwise 'invisible'? If Kamailio is not the right thing to do this with, is there something else that could do it? Thanks for any suggestions. Dominic

Folks, I'm trying to figure out if either Kamailio or OpenSIPs provides the various overload control algorithms recommended in the IETF or elsewhere. I haven't found documentation to this effect. Has anyone looked into this or used such techniques? Thanks, Mike

rtimer execution period - round two
by Alex Balashov 25 Jul '12

25 Jul '12

Hi Daniel, I wanted to go back to this thread for a minute: http://lists.sip-router.org/pipermail/sr-users/2012-June/073663.html Sorry that I didn't reply to the thread; I no longer have the last message. In your reply, you said: > there is no timeout on the execution of that task. Of course, you > can start many rtimer processes to do same task, up to you, > via configuration parameters. A matter of how rtimer executed > route is built, a rtimer process may not rest (e.g., sleep) and > keep consuming mqueue items as long as the queue is not empty." However, I am seeing some behaviour that is rather different. Roughly, I have a single rtimer task that runs every 3 seconds and consumes an mqueue full of accounting events. The rtimer request route looks like something this: route[ACCT_WRITER] { while(mq_fetch("acct_write")) { # Some stuff to write $mqv(...) values to PostgreSQL. ... sql_query("ca", "SELECT * FROM acct_event_proc(...)"); ... mq_pv_free("account_write"); } } And the rtimer task is parameterised thusly: modparam("rtimer", "timer", "name=acct_write;interval=3;mode=1") modparam("rtimer", "exec", "timer=acct_write;route=ACCT_WRITER") And the mqueue: modparam("mqueue", "mqueue", "name=acct_write") I have a stored procedure - let's call it acct_event_proc() - that is invoked from within the rtimer task. When I looked at the live query activity from Kamailio to Postgres by doing a packet capture on loopback, like this: tcpdump -i any -A -s 0 -tttt -n 'tcp port 5432' | grep acct_event_proc What I saw was some events being written for about ~3 seconds and then the process would stop. Then, after about half a second, it would burst again for 3 seconds, then stop again. And so on and so forth. When I lowered the interval to 1 second, it got faster and more responsive, and would push more events through in one interval. But still, it appeared to be a limited "burst" of SELECT calls punctuated by 1 second of silence. When I checked out branch 3.3 and lowered the interval to 50000u, it got even faster, almost real-time enough to keep up. Still, I did not really know what was happening, so I added an MI command to HEAD to check mqueue size live: http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=commit;h=41f771… (I think it would be quite useful anyhow, as there is no runtime mqueue info available right now.) Using it, I confirmed my impression: the bigger the rtimer interval, the larger the queue grows, and the slower the events seem to be written overall. The shorter the rtimer interval, the faster they are dequeued, and the smaller the mqueue is overall, in the course of normal call processing. Thus, my impression is that the execution time of the rtimer task is bounded by the interval, and that the core kills the forked rtimer task currently running prior to starting another one. Can you shed some light?

Cleanup location table on failed NAT ping
by David 25 Jul '12

25 Jul '12

Hello, I am using kamailio 3.2.3. I am using the nathelper module to "ping" users in the location table to keep the NAT bindings alive. In the event of 3 failed NAT pings, I would like to mark the entry as "unavailable" or completely delete it from the location table to avoid having stale data. Is this a feature that exists ? Is not, are their plans for it in the future ? When the REGISTER expires after 3600, if the phone doesn't register, the location entry gets cleaned up. So I have to wait up to one hour before the bad entry is purged. I was hoping to have it purged sooner. Thanks, David version: kamailio 3.2.3 (x86_64/linux) 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: unknown compiled on 14:19:23 Apr 19 2012 with gcc 4.4.3

Kamailio with APNS
by Duong Manh Truong 24 Jul '12

24 Jul '12

Hi list, My team are developing a SIP client for mobile running iOS , then having to deal with the "back ground mode" problem while this soft is installed on mobiles One of the solutions is using APNS. (Apple Push Notification Service) I wanna to use Kamailio as SIP Redirect / Proxy for my current SIP server The model is like that: User A <---------> Kamailio <---------> SIP server <--------> User B IF UserA call UserB, UserB is not available now (not registered yet), normally, SIP server will reply Kamailio with "404 Not found" In that case, i want to set up Kamailio do the communication with APNS and waiting for UserB "Wake up" then RESEND the Invite message ...... (instead of forwarding this 404 message to UserA) I am getting stuck at how Kamailio can control "404 Not found" message which it receives from SIP server . I do searching around several days but still can not get any clearer points. Please help me with some instruction/ configuration of Kamailio for this case ! Thank you very much.

Re: [SR-Users] How to rewritehostport() dynamically?

Try modifying the request URI with $ru/$rU/$rd/$rp instead. See the pseudovariables page on the dokuwiki for more information. rewritehostport() is a legacy function that does not deal with variables. -- Alex -- Sent from my Samsung mobile, and thus lacking in the refinement one might expect from a proper keyboard.

uac module From header rewriting problems
by Timo Teras 20 Jul '12

20 Jul '12

Hi, I fixed some uac From rewriting issues in commit e1d1c774c9ac0b4d, however even with the latest versions I'm still seeing corruption in From headers when they are rewritten for the whole dialogue (from_restore_mode=auto, the default). I spent some time analyzing the problem and the problem seems to be connected with the fact that only the bitwise difference of the original and modified URI are stored (XOR). The only purpose for this appears to be the idea to save only the difference in the rr params instead of two full URIs. However, it appears that in many cases (especially call transfer) the From header will be altered during dialogue. This is explicitly allowed in RFC 3261 § 20.20: The From header field indicates the initiator of the request. This may be different from the initiator of the dialog. I've seen this in practise with few commercial SIP stacks. Sometimes the changes are minor, or even trivial - but with the difference encoding having even one character changed (e.g. case), being deleted or added will result in the whole header being corrupted. I'm now wondering if we should just store both URIs in the rr params. While taking little more space, it should fix us sending garbage to the wire (which usually results in dropped call as the remote will reject the garbage messages). Any better ideas? Cheers, Timo

Kamailio as SBC and far end nat
by Martin Schiøtz 19 Jul '12

19 Jul '12

Hi I'm trying to configure kamailio version 3.3.0 to be a Session Border Controller which only purpose is to handle far-end-nat. On the far end site I have a SIP client with IP '192.168.1.2' which is NAT'ed to IP 'zz.zz.85.230'. The SIP ALG is disabled on the NAT firewall. The SIP client is communicating with the kamailio server and the Kamailio server is forwarding every thing to an Avaya SIP server 'xx.xx.173.15' and vice versa. The kamilio is konfigured to do this stateless. The REGISTER and SUBSCRIBE part works fine. The kamailio is using the 'Via:' field and I also needed to do subst on the 'Contact:' field in order for our SIP server to communicate back to the kamailio. But when I get to the NOTIFY packet from the SIP server to the kamailio there is no 'Via:' field or any other information about the SIP clients IP/port and the Kamailio just sends back 'SIP/2.0 404 Not here.' to the SIP server. I guess that this can not be solved with a statless kamailio? I guess that I need some kind of state table in the kamailio - is that possible without doing REGISTER directly with the kamailio? Any other good ideas are welcome?

Reply 503 was replaced to 500
by Uri Shacked 18 Jul '12

18 Jul '12

Hi, Kamailio server is behind our company's softswitch and acts as a sip application server. I notice that there are calls that the softswitch replied with 503 "service unavailable" and kamailio sent to the originator leg 500 "service unavaileable". When kamailio recieved 504 or 502 it sends them back as is. shouldn't it be the same with 503? It also does not have a "to tag" in the CDR. And the "to tag" in the 503 that was recieved is not equal to the 500 reply "to tag" kamailio sent back. any ideas? BR, Uri

Topoh address
by Alex Balashov 17 Jul '12

17 Jul '12

A whole ago, it was mentioned on the list that there was some bug or issue in Topoh that precluded the use of the actual host IP of the proxy as the Topoh spoof address. Is that still true in 3.3? Or has that been fixed some time ago? Thanks! -- Alex -- Sent from my Samsung mobile, and thus lacking in the refinement one might expect from a proper keyboard.

How to use regular expression for $var ?

Kamailio 3.3.0 I have a variable $var(s:dst). It can store either a number or IP. How do I check to determine whether it is a number of IP? I tried the following and it did not work: If ($var(s:dst) =~ "^\d+\.\d+\.\d+\.\d+$"){ It is a IP. }else{ It is a Number } Thanks Gary

Adding "make menuconfig"
by aft 14 Jul '12

14 Jul '12

Hi, Kamailio is a modular stack. So inclusion or exclusion of a module is very important. At this moment editing modules.lst is very *primitive* way of doing things. I like menuconfig style ncurses based interface. Which gives a very clear view of "dependency" and "which and which" information about the modules. As number of modules increases, most of us just compile most of them, or take the default modules.lst as granted. If a menuconfig target is added, it should be easier to customize a kamailio build. Adding a menuconfig target seems a trivial task for anyone who know kamailio build system well plus some intro to ncurses programming. So i guess devs should look into it. cheers aft

Kamailio v3.1.6 released - the last packaging in 3.1.x series

Hello, this morning I packaged the 3.1.6 to mark the last release in the 3.1.x series. At this moment, the latest stable series are 3.2.x and 3.3.x, so there is no intention of packing again a 3.1.x version -- although patches may still go in branch 3.1. Notes about v3.1.6 release were posted on the news section of the website: * http://www.kamailio.org/w/2012/07/kamailio-v3-1-6-released/ Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Seattle, USA, Sep 23-26, 2012 - http://asipto.com/u/katu Kamailio Practical Workshop, Netherlands, Sep 10-12, 2012 - http://asipto.com/u/kpw

Kamailio + dialog + dispatcher (limiting calls)
by George Breahna 13 Jul '12

13 Jul '12

I am trying to limit the total number of concurrent calls processed by Kamailio and I'm having a world of trouble. We are running Kamailio 3.2.3 on Debian Squeeze with the dispatcher module and recently enabled the dialog module. The call flow is extremely simple. We have two Asterisk servers to which we load balance the incoming calls to, nothing more. Our dialog configuration is the default kamailio config, with the following additions: modparam("dialog", "enable_stats", 1) modparam("dialog", "dlg_flag", FLD_DLG) modparam("dialog", "hash_size", 4096) modparam("dialog", "profiles_with_value", "callquota") modparam("dialog", "default_timeout", 300) modparam("dialog", "dlg_match_mode",2) modparam("dialog", "detect_spirals", 1) modparam("dialog", "db_mode", 0) in request_route we have: if ( method=="INVITE" ) { t_on_failure("FAIL_ONE"); ds_select_dst("1","4"); # sl_send_reply("100","Trying"); t_reply("100", "Trying"); dlg_manage(); setflag(FLT_ACC); # do accounting $var(SIZE) = 0; get_profile_size("callquota", "$rU", "$var(SIZE)"); if( $var(SIZE) >= MAX_NUMBER_OF_CALLS ){ xlog("DEBUG: Simultaneous calls limit reached for $rU: $var(SIZE)\n"); sl_send_reply("503", "Simultaneous calls limit reached"); exit; } set_dlg_profile("callquota","$rU"); if (get_profile_size("callquota","$var(SIZE)")) { xlog("DEBUG: there are $var(SIZE) total calls for $rU\n"); } forward();#uri:host, uri:port); exit(); } We also added a dlg_manage() in WITHINDLG if (is_method("BYE")) { dlg_manage(); setflag(FLT_ACC); # do accounting ... setflag(FLT_ACCFAILED); # ... even if the transaction fails } The problem is that some dialogs never get erased. Their total number always increases and their state is always 1 kamctl fifo profile_list_dlgs callquota dialog:: hash=2161:28334339 state:: 1 ref_count:: 1 timestart:: 0 timeout:: 0 In the debug logs I see these entries for the dialog module: ### Starting Call Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=515 a=25 n=dlg_manage Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:523]: no dialog callid='1560428909_26358995(a)4.55.13.227' found Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:523]: no dialog callid='1560428909_26358995(a)4.55.13.227' found Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:553]: no dialog callid='1560428909_26358995(a)4.55.13.227' found Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:309]: new dialog on hash 2161 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_handlers.c:271]: route_set <sip:1.2.3.4;lr=on>, contact sip:+118884936245@4.55.13.227:5060, cseq 402 and bind_addr udp:10.10.10.1:5060 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:583]: ref dlg 0x7feb80ef0ae8 with 1 -> 1 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:603]: ref dlg 0x7feb80ef0ae8 with 1 -> 2 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:621]: unref dlg 0x7feb80ef0ae8 with 1 -> 1 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=525 a=27 n=set_dlg_profile Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:459]: ref dlg 0x7feb80ef0ae8 with 1 -> 2 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:461]: dialog id=28334339 found on entry 2161 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:621]: unref dlg 0x7feb80ef0ae8 with 1 -> 1 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:514]: ref dlg 0x7feb80ef0ae8 with 1 -> 2 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:517]: dialog callid='1560428909_26358995(a)4.55.13.227' found#012 on entry 2161, dir=1 Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: CRITICAL: dialog [dlg_hash.c:650]: bogus event 6 in state 1 for dlg 0x7feb80ef0ae8 [2161:28334339] with clid '1560428909_26358995(a)4.55.13.227' and tags 'gK0251b91f' '' Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:808]: dialog 0x7feb80ef0ae8 changed from state 1 to state 1, due event 6 (ref 2) Jul 12 22:38:34 debian1 /usr/sbin/kamailio[25452]: DEBUG: dialog [dlg_hash.c:621]: unref dlg 0x7feb80ef0ae8 with 1 -> 1 ### Hanging up now Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25456]: DEBUG: tm [uac.c:182]: DEBUG: dlg2hash: 29877 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25456]: DEBUG: tm [uac.c:182]: DEBUG: dlg2hash: 29874 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:514]: ref dlg 0x7feb80ef0ae8 with 1 -> 2 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:517]: dialog callid='1560428909_26358995(a)4.55.13.227' found#012 on entry 2161, dir=1 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: CRITICAL: dialog [dlg_hash.c:650]: bogus event 7 in state 1 for dlg 0x7feb80ef0ae8 [2161:28334339] with clid '1560428909_26358995(a)4.55.13.227' and tags 'gK0251b91f' '' Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:808]: dialog 0x7feb80ef0ae8 changed from state 1 to state 1, due event 7 (ref 2) Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:621]: unref dlg 0x7feb80ef0ae8 with 1 -> 1 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: ERROR: *** cfgtrace: c=[/etc/kamailio/kamailio.cfg] l=625 a=25 n=dlg_manage Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:459]: ref dlg 0x7feb80ef0ae8 with 1 -> 2 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:461]: dialog id=28334339 found on entry 2161 Jul 12 22:38:46 debian1 /usr/sbin/kamailio[25455]: DEBUG: dialog [dlg_hash.c:621]: unref dlg 0x7feb80ef0ae8 with 1 -> 1 Is my config wrong ?

failure route correct..?
by Gertjan Wolzak 13 Jul '12

13 Jul '12

Hello All, I am trying to get a failure route to work, I have got it working partially. When a call comes in, first I check the db_alias, if that is positive I do a lookup location and relay if the location is valid. But sometimes the sip client is still registered in the location table, but not connected anymore, mainly with wifi connected clients. So, I have got the time out on 3 seconds (fr_timer). When that hits I have configured the following failure route: failure_route[NOTONLINE] { xlog("SCRIPT: Notonline failure route\n"); t_on_failure("STOP"); if (t_is_canceled()) { exit; } if (t_check_status("408")) { xlog("SCRIPT: Status is time out"); $rU = $avp(orig_called); /( called number and alias id not equal, so have to revert the rU back to the called number)/ prefix("9993"); /( needed to get the right manipulation done within asterisk)/ xlog("SCRIPT: uri is $ru"); $ru = "sip:" + $rU + "@w.x.y.x:5060"; xlog("SCRIPT: uri is $ru"); (w.x.y.z ip address of the asterisk box) append_branch(); t_relay_to_udp("w.x.y.x","5060"); break; } } I am not sure if the above is correct. I have based this on an old "voicemail" failure route I could find. It is working correct, the call is forwarded to an Asterisk box, where some manipulation is done and then send to an pstn gateway. The only problem I have is one way audio. RTP from the called number reaches the callee but not vice versa. Now I am wondering, can that be caused by the failure route, or should I be looking in another direction? Hope someone can give me a pointer. Thanks. Gertjan Wolzak

preparing release of v3.1.6

Hello, later today I plan to package v3.1.6 as the last release in 3.1.x series. Based on our release policy to work on latest two stable branches, 3.1 got out of by release of 3.3.0. The branch 3.1 may still get patches, it is not a closed branch, but it is a matter of developers for willing to do that -- it is just not going to be packaged again in a numbered release, so people will have to use git branch.

Re: [SR-Users] sip over tls is not working
by Peter Dunkley 12 Jul '12

12 Jul '12

Hi, I have just built Kamailio from Git master, configured TCP and TLS, and an HTTP event route. I was able to connect to Kamailio over TLS using Google Chrome (and saw the "SSL Error: The site's security certificate is not trusted!" page). After I clicked on "Proceed anyway" I saw the log message I put in the HTTP event route come out. I also logged in with Jitsi using TLS and that worked fine too. I tried this with both the WebSocket module loaded and without it, and it worked in both cases. I also tried the above with TCP and that worked fine as well. As far as I can tell TLS is working in Kamailio Git master.

Kamailio Unexpectedly Terminating
by Akan 12 Jul '12

12 Jul '12

I have 2 servers running Solaris and Kamailio 3.2.3 where on one Kamailio is terminating when it tries to save the location for a register request and the other is producing a core dump when processing an Option request. I have one server handling Register request while the other sip server forwards the register requests and handles the other requests. I have included the backtraces from the core dumps and the output from the log for the registrar server as well as the command that is causing kamailio to terminate: if (!save("location")) sl_reply_error(); 4(3364) ERROR: *** cfgtrace: c=[/opt/kamailio-3.2/etc/kamailio/kamailio.cfg] l=714 a=17 n=if 4(3364) ERROR: *** cfgtrace: c=[/opt/kamailio-3.2/etc/kamailio/kamailio.cfg] l=711 a=26 n=save 14(3374) : <core> [pass_fd.c:293]: ERROR: receive_fd: EOF on 15 14(3374) DEBUG: <core> [tcp_main.c:3555]: DBG: handle_ser_child: dead child 4, pid 3364 (shutting down?) 14(3374) DEBUG: <core> [io_wait.h:617]: DBG: io_watch_del (1003743d8, 15, 0, 0x0) fd_no=18 called 0(3360) ALERT: <core> [main.c:751]: child process 3364 exited by a signal 10 0(3360) ALERT: <core> [main.c:754]: core was not generated 0(3360) INFO: <core> [main.c:766]: INFO: terminating due to SIGCHLD 6(3366) INFO: <core> [main.c:817]: INFO: signal 15 received 1(3361) INFO: <core> [main.c:817]: INFO: signal 15 received 2(3362) INFO: <core> [main.c:817]: INFO: signal 15 received 3(3363) INFO: <core> [main.c:817]: INFO: signal 15 received 5(3365) INFO: <core> [main.c:817]: INFO: signal 15 received 7(3367) INFO: <core> [main.c:817]: INFO: signal 15 received 8(3368) INFO: <core> [main.c:817]: INFO: signal 15 received 9(3369) INFO: <core> [main.c:817]: INFO: signal 15 received 10(3370) INFO: <core> [main.c:817]: INFO: signal 15 received 11(3371) INFO: <core> [main.c:817]: INFO: signal 15 received 12(3372) INFO: <core> [main.c:817]: INFO: signal 15 received 13(3373) INFO: <core> [main.c:817]: INFO: signal 15 received 14(3374) INFO: <core> [main.c:817]: INFO: signal 15 received 0(3360) DEBUG: presence_xml [presence_xml.c:347]: start 0(3360) ERROR: ctl [ctl.c:379]: ERROR: ctl: could not delete unix socket /tmp/kamailio_ctl: Permission denied (13) 0(3360) DEBUG: <core> [db_pool.c:102]: removing connection from the pool 0(3360) DEBUG: db_postgres [km_pg_con.c:122]: PQfinish(100842470) 0(3360) DEBUG: db_postgres [km_pg_con.c:126]: pkg_free(1004c1f30) 0(3360) DEBUG: tm [t_funcs.c:122]: DEBUG: tm_shutdown : start 0(3360) DEBUG: tm [t_funcs.c:125]: DEBUG: tm_shutdown : emptying hash table 0(3360) DEBUG: tm [t_funcs.c:127]: DEBUG: tm_shutdown : removing semaphores 0(3360) DEBUG: tm [t_funcs.c:129]: DEBUG: tm_shutdown : destroying tmcb lists 0(3360) DEBUG: tm [t_funcs.c:132]: DEBUG: tm_shutdown : done Thanks Nathaniel

sip over tls is not working

Hi, I have enabled tls parameters as follows: in kamailio.cfg listen = tls:<IP>:<PORT> in tls.cfg [server:<IP>:<PORT>] method = TLSv1 verify_certificate = no require_certificate = no private_key = /usr/local/etc/kamailio/kamailio-selfsigned.key certificate = /usr/local/etc/kamailio/kamailio-selfsigned.pem Now if i try to connect to this interface using openssl s_client, it does connects, but now server certificate is sent from kamailio. kamailio log shows this : <core> [ip_addr.c:247]: tcpconn_new: new tcp connection: <CLIENT IP> <core> [tcp_main.c:1089]: tcpconn_new: on port 40727, type 3 <core> [tcp_main.c:1400]: tcpconn_add: hashes: 2614:2652:2494, 2 <core> [io_wait.h:390]: DBG: io_watch_add(0x82535e0, 23, 2, 0xb5701580), fd_no=11 <core> [io_wait.h:617]: DBG: io_watch_del (0x82535e0, 23, -1, 0x0) fd_no=12 called <core> [tcp_main.c:4296]: tcp: DBG: sending to child, events 1 <core> [tcp_main.c:3963]: WARNING: send2child: no free tcp receiver, connection passed to the least busy one (3289651) <core> [tcp_main.c:3967]: selected tcp worker 0 0(8) for activity on [tls:<IP>:<PORT>], 0xb5701580 <core> [tcp_main.c:3576]: BUG: handle_ser_child: fd -1 for 0 (pid 2491) I'm using kamailio from git. its updated to the latest.

GRUU support in Kamailio
by Olle E. Johansson 11 Jul '12

11 Jul '12

Hey, Been trying to understand the GRUU support in Kamailio. I see that the registrar saves sip.instance - but I don't see any functions to generate gruu URIs or store them. A public GRUU is valid forever for a sip.instance and should propably be saved into some sort of database table. A temporary GRUU is only valid for as long as a device registers with the same Call-ID. Please give me pointers to what I have missed! Thanks, /O --- * Olle E Johansson - oej(a)edvina.net * Cell phone +46 70 593 68 51, Office +46 8 96 40 20, Sweden

DB create statements
by Klaus Darilion 11 Jul '12

11 Jul '12

Hi! For some reason I need to the enter the SQL statements manually on the DB server (I do not want to copy the scripts to the DB server and there is no superuser access over the network) Is there a simple method to get all the SQL commands to create the kamailio database? I see there are all the files in "/usr/share/kamailio/postgres/" and lots of other SQL statements in /usr/lib/kamailio/kamctl/kamdbctl.pgsql. Does anyone know of a simple method to get all the raw SQL queries? Thanks Klaus

usrloc concurrency
by Alex Balashov 11 Jul '12

11 Jul '12

(Reposting from sr-dev because, in retrospect, it makes more sense here.) Does anyone know of any issues running usrloc with DB backing ('location') in a multi-master DB-replicated environment? I am referring to plain usrloc, not p_usrloc. I have such an environment set up with db_mode = 1 (immediate write-through) and have run into a problem where Kamailio occasionally stops writing to the location table for no apparent reason. I am wondering if this is because another Kamailio instance bound to the secondary replica is performing a DB sync as well, and at some point they collide in some sort of race condition. Would db_mode 2 fix? Would anything fix? Is this even the problem? -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com

How to proxy/authenticate on third party sip server?
by intel＠intrans.baku.az 10 Jul '12

10 Jul '12

Can anybody help me with configuration kamailio to authenticate call on 3rd party server? I want to authenticate(and proxy) call's on other server. for example, user A have account on my server(let it be A(a)myserver.com) and account on other server (let it be AA(a)hisserver.com) myserver.com keeps A's credentials for AA(a)hisserver.com when A is registered on myserver.com, he make call to B(a)othersip.com (using myserver.com as a proxy) Kamailio on myserver authenticate itself on hisserver as AA(a)hisserver.com, makes call to destination, and connect it to A. How can I setup kamailio for such behavior? Which module should I use? UAC seems can authenticate on another server, but I don't sure that it do what I want. (I've tried it, but without much success)

[Fwd: [sr-dev] WebSocket Server support in Kamailio master]
by Peter Dunkley 09 Jul '12

09 Jul '12

-------- Forwarded Message -------- From: Peter Dunkley <peter.dunkley(a)crocodile-rcs.com> Reply-to: Development mailing list of the sip-router project <sr-dev(a)lists.sip-router.org> To: sr-dev(a)lists.sip-router.org Subject: [sr-dev] WebSocket Server support in Kamailio master Date: Sat, 7 Jul 2012 18:29:23 +0100 Hello, I have merged the pd/websocket branch into Kamailio master. This means that you can now connect SIP over WebSocket (draft-ibc-sipcore-sip-websocket-02) clients to Kamailio using the "ws://" and "wss://" protocols. Some customisation of the websocket module is possible through modparams, but for most users the defaults should be OK. The WebSocket module uses the xhttp and sl modules for the initial handshake, and (unless you have both a Kamailio installation and WebSocket SIP client supporting GRUU, Outbound[1], and Path[2]) nathelper for request routing and the core force_rport() function for response routing (a new nat_uac_test() has been added to detect whether a message has arrived on a WebSocket). There is an example kamailio.cfg in the websocket module directory. [1] Kamailio does not currently support Outbound [2] I have not updated the Path module for WebSockets I believe that, once Kamailio supports Outbound and WebSocket support is added to the Path module (and you have a SIP over WebSocket client that supports this), it will be possible to use the websocket module without the nathelper module and force_rport() and without needing to change the websocket module or Kamailio core code. If you want to use secure WebSockets (wss) as well as ordinary WebSockets just configure TLS and listen on an appropriate port. I have added WebSocket support to some modules, but there are definitely going to be others (modules/lcr, modules/sipcapture, modules_k/nat_traversal, modules_k/path, modules_k/seas, and modules_k/snmpstats, at least) that need updating too. WebSockets is an unusual transport, so I have put a few notes together for anyone who needs to use it in the code (including adding support to additional modules): - A WebSocket server cannot initiate a WebSocket connection. So a WebSocket connection (over TCP or TLS) is like a TCP/TLS connection coming from behind a NAT. This is why nathelper aliasing and force_rport() is used for the routing, and "set_..._no_connect()" is always used (it's set within the websocket module). - WebSocket (PROTO_WS) and secure WebSocket (PROTO_WSS) connections are just upgraded TCP and TLS connections, so there are no listening sockets for PROTO_WS and PROTO_WSS. This means that, when deciding on what transport is being used, you need to look at the proto set in the tcp_connection, receive_info, and/or dest_info structure for the message - looking at the socket_info structure (that the message has arrived on or will be sent on) will not give you the right answer. - Although WebSocket (PROTO_WS) and secure WebSocket (PROTO_WSS) are different internal protocols there is only one SIP transport type for both ";transport=ws" (WS and WSS are explicitly used in Via: headers though). This means that you can't tell whether the transport parameter in an R-URI, Route/Record-Route, or Contact-URI is for WebSockets or secure WebSockets. As long as the message makes it into the WebSocket module everything will be OK as that module sorts it all out, but it has led to slightly more complex checks being required in some of the code relating to record-routing to handle this - and it may have an effect on other modules too. Please give the new module a go and let me know about any issues you find, Peter -- Peter Dunkley Technical Director Crocodile RCS Ltd _______________________________________________ sr-dev mailing list sr-dev(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev -- Peter Dunkley Technical Director Crocodile RCS Ltd

Removing display-name with uac_replace_from
by Andreas Granig 09 Jul '12

09 Jul '12

Hi, in kamailio 3.3, doing uac_replace_from("", "$var(myuri)"); doesn't remove the old Display part anymore (although the documentation still says it should), the debug log is: DEBUG: uac [uac.c:499]: dsp=(nil) (len=0) , uri=0x7fff87f6b840 (len=28) DEBUG: uac [replace.c:324]: uri to replace [sip:a@example.org] DEBUG: uac [replace.c:325]: replacement uri is [sip:b@example.org] DEBUG: uac [replace.c:383]: encode is=<UEtlSyomCD8kIi8/SnlZMzNyS29QS2VLanBKeg--> len=40 So no hint that the old display is being removed. When doing uac_replace_from("foo", "$var(myuri)"); then there's an additional line like this: DEBUG: uac [replace.c:284]: removing display ["olddisplay"] which is missing when I put an empty string in the first parameter.

future features?
by 张 09 Jul '12

09 Jul '12

Hello Dear all, I'm new one to participate into this discussion. I have worked on VOIP and SIP communication solution for several years. I'm very excited about the new features in v3.3. They save me many work which I planed to dig hard. My question is whether there is a web page or discuss forum for future features for Kamailio? There is a fure feature page on sip-router.org but it's very out of date. I think it's important to catch up with potential wanted feature and the new draft which is closely watched by kamailio team. Thanks! Best Regards Victor

ACK and BYE messages uses wrong socket.
by Gary Chen 05 Jul '12

05 Jul '12

Kamailio 3.2.0 I am trying to setup kamailio to do the sip trunking. It receive the sip traffic from customer and then send it to carrier. I have two NIC interface's assigned with three IP's: Interface 1: ( Public IP's) x.x.130.34 x.x.130.36 floating IP interface 2: (private IP's) 10.10.1.31 .36 is a floating IP assigned by Linux-HA (heartbeat/pacemaker). I only want to use .36 to receive and send sip traffic. I uses force_send_socket() to send INVITE with .36 IP. But the ACK message always want to use .34 IP even the Route header has .36 in it unless I force it with force_send_socket() . How can I fix this problem?

Releasing v3.1.6 - end of packaging maintenance for 3.1 branch
by Daniel-Constantin Mierla 03 Jul '12

03 Jul '12

Hello, in the near future I will package 3.1.6 to mark the end of releasing from 3.1 branch. Of course, patches can still go into that branch, but there is no intent to package again from it. If anyone is willing to push other commits before the packages, please do it in then next 1-2 days. I will do it when I get enough spare time for it, with a short notice before it in that day. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Seattle, USA, Sep 23-26, 2012 - http://asipto.com/u/katu Kamailio Practical Workshop, Netherlands, Sep 10-12, 2012 - http://asipto.com/u/kpw

Binding arbitrary TLS socket
by Andreas Granig 02 Jul '12

02 Jul '12

Hi, Got some problems when I tried this, not sure how this is intended to work: listen=tls:192.168.51.133:4343 When starting kamailio 3.3, I get the following error: ERROR: <core> [tcp_main.c:2915]: ERROR: tcp_init: bind(10, 0x7f5eea45db24, 16) on 192.168.51.133:4343 : Address already in use ERROR: tls [tls_init.c:314]: Error while initializing TCP part of TLS socket 192.168.51.133:4343 What works though is if I explicitely bind a TCP socket one port below the TLS socket, like this: listen=tcp:192.168.51.133:4342 listen=tls:192.168.51.133:4343 Is this how it's intended to work? Is there a specific reason for this behavior? Andreas

cfgutils lock / unlock + $sht() variables.
by Vitaliy Aleksandrov 02 Jul '12

02 Jul '12

Hi all, I use $sht() pseudo-variabled provided by htable module for caching various information about sip customers. I thought that htable has some locking mechanism inside it and today while i was reading core-cookbook i payed attention to one example with the lock/unlock functions and $sht(): lock("calls-to::10.10.10.10"); $sht(a=>calls-to::10.10.10.10) = $sht(a=>calls-to::10.10.10.10) + 1; unlock("calls-to::10.10.10.10"); According to that example an explicit locking mechanism should be used when i want to write something to a hash table. On the other hand there are no locks in htable documentation. So the question is when do the explicit locks should be used and for what purpose ?

Klaus / Daniel Thanks again for assistance with this. I've tried the solution based on add_contact_alias() and handle_ruri_alias() and it works perfectly.

Segfault running 3.3.0 with registrar/p_usrloc/path
by Dan-Cristian Bogos 28 Jun '12

Hey Guys, After upgrading from 3.2.x to 3.3.0 (out of debian packages and fixing db side) Kamailio is crashing on processing REGISTER. This crash only happens for updates (or if a stale contact for the same AOR is already present), not initial REGISTERs. Attached you can find the log taken with debug=6 as well as the REGISTER package producing the segfault.

Have in mind that in 3.x the accuracy is in milliseconds: <http://kamailio.org/docs/modules/stable/modules/tm.html#fr_timer> http://kamailio.org/docs/modules/stable/modules/tm.html#fr_timer Another new features in 3.x is that apart of using avps to set it per transaction (still in seconds), there is a new function that can be used to set it in milliseconds per transaction: <http://kamailio.org/docs/modules/stable/modules/tm.html#t_set_fr> http://kamailio.org/docs/modules/stable/modules/tm.html#t_set_fr Cheers, Daniel

I'm not an expert on this, but I'll post my experience and I hope that helps. I'm using Kamailio 1.5, so perhaps YMMV. I have fr_timer set to 2 seconds and fr_inv_timer set to 60 seconds. The latter can be overridden by fr_inv_timer_avp so users can alter their own timers. I do not let users change fr_timer. The behavior I see is the device has 2 seconds to give a provisional response to an INVITE. If the device has powered off, changed IP, etc. this timer will quickly return an error. If the device is responsive and, for example, sends a 180 Ringing, the fr_timer ceases to apply and the fr_inv_timer waits 60 seconds before giving up and triggering a 408 Timeout. Corey
