[Freeswitch-dev] iksemel
by Kristoff Bonne 20 Dec '09

20 Dec '09

Hi all, Can somebody please explain how exactly the "iksemel" library works. I've been trying to hunt down the bug that causes freeswitch to crash when making a jingle/gtalk call from ubuntu Empathy instead of the google talk web/flash application. I have narrowed the issue down to the difference in jingle-messages call-setup messages send over the jabber-channel by empathy, compaired to what the google webapplet sends. (see http://jira.freeswitch.org/browse/LBDING-18 for more info on the exact differences). However, I'm trying to understand how exactly freeswitch processes these messages. So, if I get it correct, it goes like that: - jabber xml-messages are treated by the iksemel library. - this library is based on "filters", which are configured beforehands. - when a jabber xml-message comes it, these filters are called. (va the function "iks_parse"). - these filters call, in their turn, the function then call a number of times the function "iks_find_attrib". In this bug, the problem seams to be when a call-setup packet comes in from empathy, on of these filters call the function "find_with_attrib", however pointing to a datarecord which is not a valid iks-record, resulting in a memory violation and hence a core-dump. But can somebody explain how exactly the "iksemel" library works. There seams to be a system of "hooks" used to attach pointers dynamically created filters-functions. But how exactly it all fits together is not very clear to me). If I understand it well, the problem needs to be solved somewhere in the code that creates these filters and define on what datarecord they should be called. However, I got lost in the code. Can somebody explain this a little bit. Cheerio! Kr. Bonne. -- jabber/gtalk: kristoff(a)krbonne.net

[Freeswitch-dev] multiple actions in an extension with different condition executing each after possible???
by rentmycoder rentmycoder 19 Dec '09

Hi pals, I would like to convert the following dialplan int fs xml dialplan, is this possible??? ;----- check for ivr vars ----- exten => s,16,GotoIf($["${IvrID}" = ""]?17:18) exten => s,17,Set(IvrID=0) exten => s,18,GotoIf($["${IvrActionID}" = ""]?19:20) exten => s,19,Set(IvrActionID=0) exten => s,20,GotoIf($["${QueeID}" = ""]?21:22) exten => s,21,Set(QueeID=0) exten => s,22,GotoIf($["${ChannelID}" = ""]?23:24) exten => s,23,Set(ChannelID=${CHANNEL_INNER}) exten => s,24,Set(CallStateID=${CALLSTATE_DIALING}) It would be easy if we could use nested conditions... <extension name="test"> <condition field="destination_number" expression="^9999$"> <condition field="${IvrID}" expression="^$"> <action application="set" data="IvrID=1"/> </condition> <condition field="${QueeID}" expression="^$"> <action application="set" data="QueeID=1"/> </condition> </condition> </extension> But we can't:( <extension name="test"> <condition field="destination_number" expression="^9999$" break="never"/> <condition field="${IvrID}" expression="^$"> <action application="set" data="IvrID=1"/> </condition> <condition field="${QueeID}" expression="^$"> <action application="set" data="QueeID=1"/> </condition> </extension> I'we tried this trick also, but second and third condition get's never executed... As a workaround I could define different extensions and use transfer to jump to the next but I have a lot of thing to check resulting a lot of extensions... There should be a more elegant way... isn't it?

[Freeswitch-dev] coredump (dingaling)
by Kristoff Bonne 17 Dec '09

17 Dec '09

Hi All, I don't know if this is the correct place for this, but I have a problem so perhaps somebody here can help. I've been playing around with freeswitch for about a week now using an old mac-mini (ppc G3) running debian. Yesterday, I wanted to give googletalk (dingaling) a try but got a coredump on freeswitch when I dialed by gtalk account from outside. Is there somewhere I can open a "ticket" for this? Can I upload the corefile (about 1.2 MB compressed) somewhere? This is on a PPC platform so I don't know if you people will have any use of it. Cheerio! Kr. Bonne. -- jabber/gtalk: kristoff(a)krbonne.net

[Freeswitch-dev] FreeSWITCH Weekly Conference Call Agenda For Dec 18 - Need Your Items
by Michael Collins 15 Dec '09

15 Dec '09

Hello friends, Just to let you know, I have posted the FS weekly conf call agenda: http://wiki.freeswitch.org/wiki/FS_weekly_2009_12_14 It's pretty clean at this point so if you've got things that you'd like to discuss with the group then please add your items to the list. If you have items that require attention, like documentation and janitorial items then by all means drop those on the list as well. One thing we do need to discuss is how we will accomplish screen casting. We are going to have presentations and we want as many people as possible to be able to view the screen while listening to the conference. Thanks, Michael

[Freeswitch-dev] multicast presence, mwi and some registrations thoughts
by Matteo 11 Dec '09

11 Dec '09

Hi all, as promised, I've created a small patch to handle PRESENCE_IN and MWI events over multicast (using mod event multicast). When used along registrations sharing with multicast, you can send presence info over the mcast-bus :) and deliver the information to the phones, even if the call is not handled on the same switch the phone sent the subscription to. To make it work, the sip domain must be the all for all the machines and on the phones, otherwise the phones will ignore them. This allows distributed BLF and MWI notifications :) BUT doing that I noticed a issue that must be addressed imho, which arises when you handle NAT. "distributed blf" works behind nat right now, since the event will get sent to all switches, but delivered only to the phone were fs knows about the subscription. Which is the one where the phone registers to. "distributed mwi" results into sending N copies of same MWI notifications , where N is the number of switches. Behind NAT the phone will receive only the one sent by the switch where it's registered to. We can avoid sending multiple event if we're able to know which is the "original" server where the phone registered to. This is also needed to call the phone: think about a distributed registration cluster. if Alice (reg'ed on FS1) calls Bob on (reg'ed on FS2), right now the call is routed from FS1 to Bob, since FS1 knows where Bob is. This works ok without NAT. But with NAT FS1 cannot contact Bob, because Bob is on FS2 "really" and can receive calls from FS2 (nat pinhole). The solution is to check where Bob is (looking to registration table), get the "real" server and route the call from FS1 to FS2 then to Bob. But right now, sofia registration does not have a field holding the "original" server. If we want to leverage on distributed registration using multicast, I think knowing the original server is "a must". the patch is pretty trivial, but we must add a field onto the db. Doing that, we can also filter MWI notification, and send them only if the phone is "really" registered on the server which receives the MWI event over the mcast-bus . What do you think about it? Regards, mat P.S. this is my first patch to FS, so please be kind on my mistakes :)

[Freeswitch-dev] dynamic update page
by vip killa 10 Dec '09

10 Dec '09

could someone tell me how it would be possible to have a webpage reload when an extension is dialed. for example a user is looking at a webpage displaying conference information. when someone enters the conference, that webpage is reloaded displaying updated information about the conference
