[Kamailio-Users] using "substr()" function from TEXTOPS in "onreply_route" block

by Alex R.S.M

Hi, I was wondering if anyone has used "substr()" function from TEXTOPS in "onreply_route" block. This function works fine in "route" and "branch_route" blocks. However, it creates duplicate fields (instead of substituting) when being used in "onreply_route" blocks. I need to modify FROM field in "onreply_route" block. As far as I know, "uac_replace_from()" function works only in request_route block, so my only option is to use "substr()". Thanks, Alex R _________________________________________________________________ Proud to be a PC? Show the world.

[Kamailio-Users] Route-problem, no 487 sent

by Magnus Burman

Something fishy is going on with my routing. If my SIP UA (91.XXX.XXX.80) hangs up before the receiving end (pstn on 212.YYY.YYY.84) answers, it keeps ringing forever. Below is my routing in regards to CANCEL and the ngrep output. If I understand things correctly, I should send a 487 Request Terminated back to the initiating UA (sip), and I would get a 487 Request Terminated from the pstn provider. I'm not sending the 487 to the UA, and I'm guessing I close the session before my pstn provider sends one to me, so I don't see it with ngrep? The big question is ofcourse what I need to do to get on track, sending the appropriate 487? route: -- #CANCEL processing if (is_method("CANCEL") || is_method("ACK")) { if (t_check_trans()) { setflag(1); if(!t_relay()) { sl_reply_error(); } } exit; }; ngrep output, comments starting with #: -- U 91.XXX.XXX.80:5060 -> 91.ZZZ.ZZZ.9:5060 CANCEL sip:6--------@91.ZZZ.ZZZ.9 SIP/2.0 Via: SIP/2.0/UDP 91.XXX.XXX.80:5060;branch=z9hG4bK1e22091bbd2d0a9b9e0f8de6553d2c27 From: "349--------"<sip:user1@91.ZZZ.ZZZ.9>;tag=XG6525p2-b915854d-1373157639 To: <sip:6--------@91.ZZZ.ZZZ.9> Call -ID: 6C8F-F261-374702698-E353C7B05C17-0006(a)91.XXX.XXX.80 CSeq: 10 CANCEL Max-Forwards: 70 User-Agent: XAVi/XG6525p2-1.6.7 Content-Length: 0 U 91.ZZZ.ZZZ.9:5060 -> 91.XXX.XXX.80:5060 SIP/2.0 200 canceling Via: SIP/2.0/UDP 91.XXX.XXX.80:5060;branch=z9hG4bK1e22091bbd2d0a9b9e0f8de6553d2c27 From: "349--------"<sip:user1@91.ZZZ.ZZZ.9>;tag=XG6525p2-b915854d-1373157639 To: <sip:6--------@91.ZZZ.ZZZ.9>;tag=bbd8f31c58bc6a3266ec5509a254d55b-cb96 Call-ID: 6C8F-F261-374702698-E353C7B05C17-0006(a)91.XXX.XXX.80 CSeq: 10 CANCEL Server: Kamailio (1.4.1-notls (i386/linux)) Content-Length: 0 # 487 Request Terminated from 91.ZZZ.ZZZ.9 to 91.XXX.XXX.80 ??

[Kamailio-Users] new feature: re.subst transformation

by Daniel-Constantin Mierla

Hello, using the latest development work and the newest pseudo-variable&transformation framework (http://lists.kamailio.org/pipermail/users/2008-December/020918.html), the textops module offers a new class of transformation for regular expressions. By now, it implements {re.subst,expression} - ability to do Perl-like substitution of string value pseudo-variables: http://www.kamailio.org/dokuwiki/doku.php/transformations:devel#re.subst_ex… Here is an example to extract username part from R-URI using this transformation: $var(user) = $(ru{re.subst,/^sip:(.*)@(.*)/\1/}); Now, the subst operation becomes very handy, old tricks to copy in R-URI and use subst*() functions from textops module, or copy in avps and use avpops module are no longer required. This implementation can be used as example by developers to learn how to export new transformations from other modules. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

[Kamailio-Users] important: transformations moved from core to pv module

by Daniel-Constantin Mierla

Hello, the pseudo-variable and transformation framework in core has been completed for upcoming v1.5.0 of Kamailio (OpenSER). The core has now only API to register, parse name, evaluate and set values for PV&T. All specific implementations have moved to PV module: http://kamailio.org/docs/modules/devel/pv.html The current architecture provides a flexible way to enhance the number PV&T available in config file without affecting the stability and the performance of core and main modules. As this number increased a lot, and will grow more, the API changed the indexing from a list to a hash table, offering faster lookup and quicker shorter up time. With this work done, a new functionality is available for developers: - they can export new transformations from their module. As example, check the pv or textops (new transformation to be announced in separate message) modules. The system is simple, you have to implement a function to parse the name of transformation and its parameter, plus a function to evaluate a transformation. Now core got some clean up, not that fat anymore, implementation of about 100 pseudo-variables and over 30 transformations was moved out (couple of thousands lines of code). This work is part of the efforts to increase the stability, performance and flexibility of the core, so that specific implementations do not affect typical use cases. As final note, remember to load the pv module from now on if you work with/need old core pseudo-variables or transformations. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

[Kamailio-Users] new module: sqlops - sql operations

by Daniel-Constantin Mierla

Hello, the devel version (to be released as 1.5.0 in Q1 2009) includes now a new module: sqlops. It can be used to do raw sql queries in config file and play with the result data. Key features: * /many DB connections/ - the module can connect to many databases on different servers using different DB driver modules (mysql, postgres, ...) at the same time. * /many DB results/ - the module can store many results of different SQL queries in separate structures at the same time. Thus is possible to work in parallel with several DB results. * /access via pseudo-variables/ - the content of SQL query result is accessible via pseudo-variables. * /array indexes/ - fast access to result values via array possition: [row,column]. * /persistence in process space/ - a result can be used many times in same worker process. Query once, use many times. Here is an example of fetching and printing the content of a table: ... modparam("sqlops","sqlcon","ca=>mysql://openser:abc@localhost/openser") ... sql_query("ca", "select * from domain", "ra"); xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n"); if($dbr(ra=>rows)>0) { $var(i) = 0; while($var(i)<$dbr(ra=>cols)) { xlog("--- SCRIPT: column[$var(i)] = $dbr(ra=>colname[$var(i)])\n"); $var(i) = $var(i) + 1; } $var(i) = 0; while($var(i)<$dbr(ra=>rows)) { $var(j) = 0; while($var(j)<$dbr(ra=>cols)) { xlog("[$var(i),$var(j)] = $dbr(ra=>[$var(i),$var(j)])\n"); $var(j) = $var(j) + 1; } $var(i) = $var(i) + 1; } } sql_result_free("ra"); ... Other advantages than the ones listed above against avp_db_query(): - does not mess up fields position if the value in db is null - use private memory, no locking - does not iterate through linked (avp) list to get each field, direct reference to each data structure in result array, thus much faster. More info at: http://kamailio.org/docs/modules/devel/sqlops.html Testing and feedback is appreciated. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

Re: [Serusers] Deadly embrace with rtpproxy - Is it necessary? Can it be turned off?

The gateway has the same > active media mode as rtpproxy. > g-) I don't believe I understand what you are asking re: active media. Are you talking about some control I can set in SER or rtpproxy? Because those are the only knobs available to me. The company sending the call to us doesn't want to change settings on their equipment to accomodate what they consider to be our incompatibility (what rtpproxy is doing), as what they are doing (not sending audio until they receive audio from us) isn't a problem when they send calls to other carriers. If you are suggesting something I have SER patch into the 183/200 SDP payload to trick the calling system to send audio without waiting to see some audio from us, what exactly are you suggesting be added and how would that be done? As a FYI, the PSTN gateway switch behind our SER system has virtually no SIP controls, as the first thing it does is make the call look as much like a TDM call as possible, right down to assigning a pseudo trunk number for the call to be carried in. Of course, this is the device that is happily sending RTP audio which rtpproxy is throwing away, so I don't think I can fix the problem from that side even if there was a knob to change something since this side is already working. And yes, you can create this same problem that I am reporting by having the audio for a call pass between two SER systems with rtpproxy on both with no NAT present whatsoever (no re-routing of audio, just bridging isolated networks). Neither rtpproxy daemon will blink until the other does, and so audio never works. This has got to be wrong. I'll point out that when I reported this a month of two ago, someone on the list came out and said rtpproxy does not do what I was reporting, can't do this, always passes audio in a given direction the instant the SDP payload for that direction passes through SER. I don't find that to be the case and the demonstration proves that the behavior is different. I also don't understand the comment above about sending back to the source port. From what I can see, rtpproxy opens four separate ports, two on each interface, one for incoming and one for outgoing on each I would assume. If not, then that would be a different bug as rtpproxy is opening twice the number of ports it actually needs. (I think it is using all four in the two-interface mode.) Please clarify what you are saying/suggesting if you can. Examples appreciated. Thanks.

[Kamailio-Users] Kamalio Support for RFC 3323 " Privacy"

by ingdavidcespedes＠cable.net.co

Hi Is there any way (special module, or something like that) to implement RFC 3323 in Kamailio. Or do I have to do it manually, by changing the header fields that require privacy and change them for something like ("Anonymous" <sip:anonymous@anonymous.invalid>) and keep the relation of this new URI with the original one, in a separate table of my database?. How can I do this in a more easy way?. David Cespedes

[Kamailio-Users] Port of kamailio to OpenBSD

by Don Jackson

I have motivated the creation of a port of kamailio to OpenBSD, the port creates binary packages, which can then be added via the pkg_add command. I could definitely use input and testing of this port from the kamailio community, if you are interested in running kamailio on OpenBSD, I could use your help! We also needed to create a port of radiusclient to support kamailio. Both ports are attached to the messages appended below.

[Kamailio-Users] reply_route is not called though a response is received

by Aurelien Grimaud

Hi, I am running a rather old version of openser, but since in a production context, I cannot upgrade anytime I want to catch up with newer releases. I searched bugs and googled for my problem without any result. There it is. I have a module with functions beginning with mn_ mn_received handle any incoming request and prints it out. my module has a callback on response which prints out responses. My configuration file is something like // handle register mn_received() ; record_route() ; if ( method=="INVITE") { t_on_failure(ROUTE_INVITE) ; t_on_reply(ROUTE_INVITE) ; } Then the request is t_relayed to destination. The onreply_route[ROUTE_INVITE] prints some output, and fix_contact on 200, ... whatever. Then this happens : - An INVITE is received from A (I see it with mn_received) - INVITE is relayed to destination B - B replies 180, I see the response on my module output and I see my onreply_route[INVITE] statements. - B replies 200, I see the response on my module output, but, I *do not* see my reply_route statements. - A sends ACK for INVITE - ACK is relayed to B 2 minutes later (fr_inv_timer), the failure_route[INVITE] is triggered ! Since I use failure routes to manage serial forking, this means openser forward the initial INVITE to the other destination, though first call was established ! Moreover, first call, which seems ok is CANCELED by the openser (I can see a 200 answer to a cancel from B) Openser did not disarm the fr_inv_timer on "200" answer to INVITE ? Openser did not triggered my onreply_route... Has someone already experienced this ? Has someone a clue where it may come from ? - Sometimes it works ok - Sometimes, 180 is not "seen" and 200 is ok - Sometimes 180 is seen but not 200 - Sometimes neither 180, nor 200 are seen - Headers in 180 and 200 are the same except for content - I'm running openser-1.2.0 (ouch !) I'm stuck ! Could this be related to 2008-05-15 10:59 Bogdan-Andrei Iancu, <bogdan at voice-system dot ro> * [r4191] modules/tm/t_reply.c: backport from trunk (rev #4190): - fixed race condition that may lead to deadlock on the transaction lock. As the reply route (t_on_reply()) stored in transaction may be changed in reply route br the current process or any other process, to avoid race conditions, it is better to make a local copy of the reply route number to be sure it will not be changed. The deadlock can appear as the reply route number is used in several conditions to determine id locking is required. But as this value may be changed (by current or other process), it may lead to multiple lockings with no unlock -> deadlock. NOTE: this might happen only if onreply_avp_mode is turned on. Aurelien
