Can any one provide some C programs showing how to use FreeSwitch APIs to build an UAC or UAS? Thanks & Regards Scott

Freeswitch on Debian repository
by Nicholas Santos 06 Feb '09

06 Feb '09

Hi, I'm the current owner of the Freeswitch package on Debian Testing (Lenny). I'm just beginning to package it, if there's something that I should know before I package it, just say it. I'm here to do my best on this that I consider a great step. Thanks in advance, Nicholas Amorim. PS: By the way, what a great piece of software! :)

Manual Attended Transfer using 3 channels
by David Dikman (a05davdi) 05 Feb '09

05 Feb '09

Hi, I'm currently implementing an operator to direct calls with using freeswitch and event socket. The operator should be able to do an attended transfer, that is the operator is supposed to be able to recieve a call, call another party and switch back and forward between these to before eventually bridging them together. (I cannot use att_xfer since it doesn't have the behaviour we wish). I've gotten everything to work fine up 'till the point where the operator has called a second party and whishes to switch back to the first party and this is where I need some help. I use event socket for sending the api commands but if I could just get a hint of how to do it manually (with console) I could probably convert it (or how to do it in js). These are the steps I go through now: (notice that I'm trying to use only 3 channels so that the operator needn't park channels on phone) * Originate call between inbound call and operator (Gives me what i'll refer to as Leg A and Leg B) * Hold Leg A (gives music to Leg A) * Transfer Leg B to Ext XX (Gives me Leg C, now I've got one call from A-B and one from B-C) * Unhold Leg B (I can talk between B and C) What should be the next step? I've tried holding C and then bridging, transfering, intercepting etc but nothing works. Whatever I do the call between Leg A and Leg B disappears and no sound between the two. I can bridge A->C and get them to talk to each other but I would also like to be able to switch back from B->C to A-B. I've been guessing my way around this for quite some time now and I would really appreciate some help.

Cisco 7975G and XML options for G722
by Brian West 01 Feb '09

01 Feb '09

I'm digging for the option in the XML to enable G722 on the 7975G, It says "Enterprise Advertise G.722, Disabled", "Device Advertise G.722, Use System Default" So what options to turn G722 on? Anyone? Anyone? Thanks, /b

[RFC] mod_entity
by John Skopis 31 Jan '09

31 Jan '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 The module is not complete. I am sending it now for some feedback as it might be a good time (mostly completed). The module, mod_entity, will build all xml entities the xml interface supports, currently it only supports directory, and dialplan (partially). The idea is that mod_entity describing xml entities, which are just collections of elements, queries a directory (dbi) for the values it needs to build the xml. mod_directory accepts a char** array of fields, and returns an ordered char ** array of values, the dn (id) of the last entry (row), and how many entries remain. I would like to hear what you think, anthm especially. I know it's not finished code but I am not sure I am in the right direction. For this module to be at all practical the xml created needs to be cached. Lets save this for another thread though. http://jira.freeswitch.org/browse/FSREPO-1 - -John -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFJhIuVopIcoit0BmcRCqNQAJ9013ALiephXYqPo3ZnsAR8LgGc8ACglpns iknUUEuRDtPC8Owo8ma0bfs= =KxVd -----END PGP SIGNATURE-----

very early prototype of SLA/BLA
by Matthew Kaufman 31 Jan '09

31 Jan '09

See http://jira.freeswitch.org/browse/MODENDP-179 for how far I've gotten on doing SLA/BLA in the draft-anil-sipping-bla-02/03 style. If the patch is applied and the feature enabled and Polycom phones in use and the phones configured for type="shared" and thirdPartyName="<some extension>", the lights really work. And with a patch Anthony provided to me today to add support for INVITE w/REPLACES, you can even put a call on hold at one phone, go to another phone with a blinking light for that line, and pick it up. (But you can't pick up a second phone with the first still on the call and have them both join the call at the same time via an auto-created conference... yet) Amazing how much work it takes to emulate an old key system. Again, this is a total rough-draft hack of a prototype, just enough to get the lights working, and with at least one major memory leak and/or nua handle leak(s) that cause bad things to happen, so isn't for production at all yet. I will be continuing to work on it myself, but I know this is something that gets requests so I wanted to get the fact that I'm working on it out in the open ASAP. Matthew Kaufman

freeswitch development question (memory allocation?)
by Apostolos Pantsiopoulos 30 Jan '09

30 Jan '09

I have the code below : struct radacct_thread_handle { switch_core_session_t *session; switch_mutex_t *mutex; switch_thread_cond_t *cond; }; static switch_status_t my_on_routing(switch_core_session_t *session){ switch_thread_t *thread; switch_threadattr_t *thd_attr = NULL; switch_memory_pool_t *pool; struct radacct_thread_handle *thread_params = NULL; pool = switch_core_session_get_pool(session); thread_params->session = session; ... } when the program reaches the last line (thread_params->session = session;) I get a core dump. Is this a memory allocation error? Is it because I am making use of the wrong pool? Please enlighten me because I am not an experienced c programmer, and I am struggling to get familiar with the FS API. -- ------------------------------------------- Apostolos Pantsiopoulos Kinetix Tele.com R & D email: regs(a)kinetix.gr -------------------------------------------

getting a session pointer within an event handler
by Apostolos Pantsiopoulos 30 Jan '09

30 Jan '09

How can I get a session pointer within an event handler? I tried to extract the uuid from the event header and then I tried to locate the session using the uuid : static void my_event_handler(switch_event_t *event) { switch_assert(event); switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "channel name : %s\n",switch_event_get_header_nil(event, "channel-name")); char* uuid = switch_event_get_header(event, "session-id"); switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "uuid : %s\n",uuid); switch_core_session_t *session; session = switch_core_session_locate(uuid); switch_assert(session); ... } But the uuid is always null. The events that I am binding my routine is for CHANNEL_CREATE (I tried CHANNEL_EXECUTE too, same result) -- ------------------------------------------- Apostolos Pantsiopoulos Kinetix Tele.com R & D email: regs(a)kinetix.gr -------------------------------------------

Recoding G729 raw payload in FreeSWITCH and G729 decoding
by seven du 27 Jan '09

27 Jan '09

Hi FreeSWITCHers, 1) FreeSWITCH support G729 codec in passthrough mode, it is normally engough if both call-legs suport G729. But there is no way to do recording if you can't decode it. I wrote a small module called mod_recpld. The idea is to record the raw payload in rtp packets to files, and decode them into 3rd party converters. See details at: http://code.google.com/p/mod-recpld/ 2) EasyG729A implemented by http://imtelephone.com can be free of use on research purpose, I made a wrapper so it can be used in FreeSWITCH. See deatila at: http://code.google.com/p/libg729/ The code is not good but just works. BTW, I think it maybe easy to store codes on FreeSWITCH svn than on google code, how can I become a developer? Can I get a svn access on svn.freeswitch.org and own a branch?
