[Freeswitch-dev] FreeSWITCH Weekly Conference Call Agenda - Oct 30th
by Michael Collins 27 Oct '09

27 Oct '09

Greetings all! I just wanted to say thank you to those who have been contributing to the documentation and cleanup efforts. Please keep up the good work. FYI, we still have lots of janitorial stuff to do. Just keep checking the latest conf call agenda for updates. This week's agenda is here: http://wiki.freeswitch.org/wiki/FS_weekly_2009_10_30 We are always looking for people to help out with documentation and other little projects so please feel free to ask me if you would like to assist. Also, we are working on having members of the community give brief presentations during the weekly conference calls. We want people to join the conference and share with the group information about how they're using FreeSWITCH in production, or they can give little tutorials on how to use various parts of FS. We are also working on getting a web-cast enabled so that we can have a little video to go with the audio. If you have something you'd like to discuss with group please let me know. Thanks for being such a great community! -Michael

[Freeswitch-dev] scheduled_event.lua
by Trixter aka Bret McDanel 24 Oct '09

24 Oct '09

I got bored, so I went ahead and added the ability for scheduled events to be assigned to a specific switch. In order for this to be accomplished I had to add an api call "hostname" so that the script can automagically determine which host it is running on in a cross platform way. The patch is at http://jira.freeswitch.org/browse/MODAPP-357 for anyone else that needs something similar. Basiscally if the switch name is * then the first available switch will process it when the time comes, if its anything else, then the "hostname" has to match. In addition I added parsing of "status" information, so it will not attempt to pull any events if the utilization is above what you have defined for the max sessions and the session rate for your system. This is not perfect since it does not look at actual system load nor does the script see if the action would create a session. In the situations where I envision this type of a scheduler being used I think almost all of the actions would create a session, and I am also going on the assumption that people have properly configured their session values to be correct for the hardware they have, so this will probably cover almost everyone in this regard. So now people can set up a cluster of boxes to automatically rig the american idol vote lines without overloading their boxes :) More practical applications include doctors offices that want to program calls a week in advance to remind patients of their appointments, perhaps based off an ical feed like google calendar and other apps use. -- Trixter http://www.0xdecafbad.com Bret McDanel pgp key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8AE5C721

[Freeswitch-dev] scheduler
by Trixter aka Bret McDanel 23 Oct '09

23 Oct '09

for anyone that is interested, in <SRC>/contrib/trixter/scheduled_event.lua there is a script, which admittedly is not very well tested (written last night) that allows for mysql events to be scheduled to be run. Why mysql and not sched_api or similar? Well this allows the scheduled events to survive past a reboot, shutdown, crash, alien abduction, or other issue. It also is written in a way to allow for many switches to each pull an event off one at a time and process them, thus distributing the load. sched_api requires that the scheduled event exist on a particular switch which can be a bit messy in some applications. So you can do a "hotel style wake up call" (good for getting out of boring meetings or bad blind dates) or really anything you want. You can start/stop the script, even change the DB credentials without a restart to allow for easier load management or maintenance. Its a trivial script, but I didnt see anything like this elsewhere. If people have specific feature requests (like adding a machine column to the table so that certain events can be scheduled only for specific machines, or only pulling events when the load is under X) let me know and I will look into doing that. The only problem that I saw last night was that it runs every "heartbeat" (FS eventing system) and if you have more tasks to accomplish in a given interval it can get a little backlogged and does not do any notification to that effect. -- Trixter http://www.0xdecafbad.com Bret McDanel pgp key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8AE5C721

[Freeswitch-dev] 3pcc proxy, INVITE w/o SDP
by Claudiu Filip 23 Oct '09

23 Oct '09

Hi guys, I have a few problems with invites w/o sdp. Given scenario: FS: global_codec_prefs=PCMU,PCMA,G729,G723,GSM A: G711 / G729 / G723 B: G729 only Call from A->FS->B: 1) A->FS invite w/o sdp 2) FS->B invite w/ sdp (PCMU PCMA G729 G723 GSM, global_codec_prefs) 3) B->FS 180 ring 4) FS->A 180 ring 5) B->FS 200 ok w/ sdp (G729) 6) FS->A 200 ok w/ sdp (PCMU PCMA G729 G723 GSM, global_codec_prefs again!) 7) A->FS ACK w/ sdp (PCMU) The result: TRANSCODING_NECESSARY, but G729 only passthrough, call cleared! Changing the global_codec_prefs to G729 PCMU PCMA, the leg A<>FS will be negotiated to G729 and it will work, but that's just a workaround. (another dirty fix was to add sofia_glue_tech_set_local_sdp(tech_pvt, b_sdp, 0); in mod_sofia.c line 482 code block 478-507, that will pass B sdp to A so the call will use the same codec on both legs and will be half proxied rtp from A goes directly to B, but if A has PCMU and B PCMA the call is dropped without transcoding) As long as leg FS<>B is already using G729, FS should advertise to A G729 first, then all others. The right setup should be: 1) A->FS invite w/o sdp 2) FS->B invite w/ sdp (global_codec_prefs) 3) B->FS 180 ring 4) FS->A 180 ring 5) B->FS 200 ok w/ sdp (codecX ) 6) FS->A 200 ok w/ sdp (codecX global_codec_prefs-codecX ) 7) A->FS ACK w/ sdp (codecX) More than that, if B has early media and step 3) is 183 ring w/ sdp, the result is " freeswitch: sofia_glue.c:2745: sofia_glue_tech_media: Assertion `r_sdp != ((void *)0)' failed. Aborted (core dumped) " but I'll post that on jira. Best regards, Claudiu Filip

[Freeswitch-dev] Doxygen configuration
by Muhammad Shahzad 22 Oct '09

22 Oct '09

Hi, Please see attached herewith doxygen configuration file for FS documentation. this should replace the one found at <FSROOT>/docs/Doxygen.conf. It has following additional features, 1. Search Engine support, with which you can search any identifier within entire documentation tree. 2. Various graphs and diagrams to illustrate position and importance of each file and how all files within a library fit together to provide specific functionality. 3. Name Space list, along with complete alphabetical index of all methods in them. 4. Documentation coverage for all FreeSWITCH modules (previously it only generates documentation for application modules). 5. Documentation for all libraries maintained by FS developers (ESL, Dingaling, Teletone and Openzap). 6. Todo list. 7. Links to access fully formated source code of each file with line numbers and syntax highlighting etc. 8. Identifier cross reference list, i.e. a list of all methods and variable who call a given method or variable. 9. UML style inheritance and collaboration diagrams. 10. Configuration for LATEX, RTF and Microsoft CHM formats also available but not enabled. Any developer who wish to have documentation in any of these format may find and enable one or more of these formats as per his/her requirements. Please review and add it to FS trunk. All comments and suggestions are welcome. Thank you. -- Muhammad Shahzad ----------------------------------- CISCO Rich Media Communication Specialist (CRMCS) CISCO Certified Network Associate (CCNA) Cell: +92 334 422 40 88 MSN: shari_786pk(a)hotmail.com Email: shaheryarkh(a)googlemail.com
