[Kamailio-Users] dialog enhancements #1
by Daniel-Constantin Mierla 04 Feb '09

04 Feb '09

Hello, during the week before freezing the code for release kamailio (openser) 1.5.0, I have added several enhancements to the dialog module. I am going to present them in several emails, as I get the documentation properly updated. There is now a new function called dlg_bridge(From, To, outbound_proxy). It can be used to connect From and To users. The mechanism is a simple call transfer scenario. kamailio => INVITE (hold) =>From kamailio <= 200ok <= From kamailio => REFER (To) =>From kamailio <= 200ok <= From ... From => INVITE ... =>To ... kamailio => BYE =>From kamailio <= 200ok <= From The function can be called from configuration file or via MI interface. It opens the door for several cute features you can do with the sip server. Here are couple of usage examples: - easy integration with web/external applications for Click-To-Dial. Doing it with kamctl will look loke: kamctl fifo dlg_bridge sip:from@kamailio.org sip:to@kamailio.org - wake up/reminder/scheduled call - use rtimer module to run scheduled calls - you can connect your user to a media server playing a message, to a conference room or where the user sets its preference - call again - when a user is calling a busy destination, when that destination becomes available, the server can initiate the call to connect the caller with the destination Documentation is available at: http://kamailio.org/docs/modules/1.5.x/dialog.html Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

[Kamailio-Users] Reg. SIP conferencing support for RFC 4579
by Padmaja R 04 Feb '09

04 Feb '09

Hi all, Is it possible to use Openser as the SIP conference server? I understand that Openser cannot do the media mixing required of a centralized media server but if it can do the centralized signaling by acting as a focus and let a media proxy do the media mixing, that would be good. I need ad hoc conferencing capability. Is there any media proxy that can achieve this together with openser? My scenario is as follows:- Say A and B are in a SIP call, and A and B suddenly decide to have a conference with C. A puts B on hold and dials C' s number. After call between A and C is up, if A presses hook flash, this sends an invite to the conference application namely: conf@openseratlocalhost:5060 (which is the ip and port number at which my openser proxy would be listening). The server should then send back 200 Ok with the contact header containing the isfocus" parameter of the form -Contact: <sip:conference1@mediaproxyip;isfocus> The isfocus is an RFC 4579 based feature. The 200 Ok responses to other invites (normal calls that do not create conference) should not include this isfocus in the contact header of 200 Ok. Finally, the openser proxy should be able to contact the media proxy on receiving an invite to create the conference and send that ip and focus information in the 200 Ok. The UA -A would then send a REFER to B and C to refer to the media server and they disconnect with A. Then all three UAs would individually send invite to the uri returned in the contact header and join the conference. Thanks, Padmaja

[Serusers] SER and media server
by Chatrapathi. H. Rahul 04 Feb '09

Hi I am using solaris 9v. I tried to use SEMS as media server with SER. SEMS is not compatible with Solaris 9v. Gives compilation errors. My query is whether any other opensource Media Server is available that uses SER and compatible with solaris 9v.This would help me a lot. Thanks in advance. -- Regards Rahul

[Kamailio-Users] New module : PURPLE - IM/Presence multi-protocol gateway
by Eric PTAK 04 Feb '09

04 Feb '09

Hello everyone, Let me introduce to you a new module, available in trunk since yesterday, so it will be included in 1.5.0 release : >From http://kamailio.org/docs/modules/devel/purple.html: *Purple module is a multi-protocol instant-messaging gateway module which use libpurple, the library on bottom of Pidgin (ex-gaim).* *This plugin was wrote in order to proof the concept of gateway between SIP and MSN/Live networks.* *[...]* *It's no really adapted to a production environment with a huge user count but can be used in order to demonstrate the concept or to use it in SOHO environment.* I hope you'll enjoy purple module, and I'll welcome all feedbacks.

With sip trace you still get them in a DB, because it first stores to DB and then sends to another address. However, what you want to achieve is something good, so for the future I will have in mind the option just to replicate to another address and skip writing to db. > Or, better to say, can I trace and duplicate messages on one > server and not log them? > If you want to duplicate the messages that come to kamailio, you can use the send() function in route and onreply_route block. http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:devel#send_destinat… If you want the siptrace module to do it, you have to hack it a bit. Practically is to introduce a new parameter, e.g., skip_db_storage, and put the code that writes in db inside a if not skip_db_storage.

Re: [Kamailio-Users] [Kamailio-Devel] New module : PURPLE - IM/Presence multi-protocol gateway
by Eric PTAK 03 Feb '09

I agree with you, the module needs improvements on that point. It's a really old point I missed when we decided to reuse and to reverse that module. I think about two manners in order to solve it : * implement a return code for purple_send_message * sending a reply directly in the module Regarding the design of the module, I think both possibilities needs a lot of mod. I'm not sure how to consider that mod as it's not a bug but a limitation. Is it a new feature I'll code when the trunk will be unfreezed ? If yes, we may add that limitation in the doc for now.

Hello all, thanks to Frederick Bullik we've now a nice documentation index for the Kamailio 1.4.x and 1.5.x releases available. You can easily lookup all module exports like functions [1] or module parameters [2]. The index is sorted alphabetically and provides convinient links to jump directly to the respective place in the module documentation. You'll find the new index in our wiki at: http://kamailio.org/dokuwiki/, as well as the old ones for past OpenSER releases. Best regards, Henning Westerholt [1] http://www.kamailio.org/dokuwiki/doku.php/modules:1.5.x:index-functions [2] http://www.kamailio.org/dokuwiki/doku.php/modules:1.4.x:index-parameters -- Henning Westerholt - Development Consumer Products / DSL Core 1&1 Internet AG, Ernst-Frey-Str. 9, 76135 Karlsruhe, Germany I'm going to FOSDEM

[Kamailio-Users] sip trace & duplicate_uri
by kokoska rokoska 02 Feb '09

02 Feb '09

Hi all, could someone be so kind and explain me how to use (or how exactly works) duplicate_uri in siptrace module? I think, if I setup modparam("siptrace","duplicate_uri","sip:1.2.3.4:5060") that all (and what is it "all"? :-) traced messages will be copied to defined sip uri (1.2.3.4:5060). I see nothing "on the wire" with ngrep, but all messages are succesufly inserted into local DB so I thing the siptrace module works. But doesn't copy messages to 1.2.3.4:5060 :-) Any hitns are really welcome! Best regards, kokoska.rokoska
