Need help in bridging two sessions in module
by Juan Backson 23 Sep '09

23 Sep '09

Hello, In my scenario, I have other_session that is doing playback of a media file within an infinitely loop. What I need to do is to be able stop the "other_session" from doing the playback, and then bridge the current session to it. With the following code, I can get the current session and the other_session to bridge, but I can't get media between the two sessions. Also, is there anyway to stop the playback? Right now, after the brdiging, other_session still hears moh. switch_core_session_t * other_session = switch_core_session_locate(bridge_to_uuid); switch_channel_t *other_channel = switch_core_session_get_channel(other_session); switch_caller_profile_t *cloned_profile; cloned_profile = switch_caller_profile_clone(other_session, switch_channel_get_caller_profile(channel)); switch_assert(cloned_profile); switch_channel_set_originator_caller_profile(other_channel, cloned_profile); cloned_profile = switch_caller_profile_clone(session, switch_channel_get_caller_profile(other_channel)); switch_assert(cloned_profile); switch_assert(cloned_profile->next == NULL); switch_channel_set_originatee_caller_profile(channel, cloned_profile); switch_core_media_bug_resume(session); switch_core_media_bug_resume(other_session); switch_ivr_multi_threaded_bridge(session,other_session, NULL, other_session, session); switch_core_media_bug_pause(session); switch_core_media_bug_pause(other_session); thx, jb

Library list
by Muhammad Shahzad 23 Sep '09

23 Sep '09

Hi, I have almost finished doxygen configuration files, however, i do need to know which libraries in <FSROOT>/libs folder are maintained by FS developers, so i also include them in documentation tree, all other libraries will be used for referencing purpose only (and assumed that they are already documented outside our docs tree). I have added following libs so far (for in-tree documentation), <FSROOt>/libs/libdangaling <FSROOT>/libs/esl <FSROOT>/libs/openzap Is this list complete? Are there any other libs which we are maintaining? Thank you. -- ________________________________________________________ | | | FATAL ERROR --- O X | |_______________________________________________________| | You have moved the mouse. | | Windows must be restarted for the changes to take effect. | | <OK> | ####################################/ 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

play background music and park the call
by Juan Backson 23 Sep '09

23 Sep '09

Hi, What I would like to do is to park an incoming call and then play a background music while it is parked. Upon occurrence of certain event, I would like to unpark the caller again and bridge it to someone else. I tried to use the following: switch_status_t status = switch_ivr_play_file(session, NULL, set_bg_prompt_data, NULL); switch_ivr_park_session ( session); It does not work. The call goes to hangup and it does not "wait" there. Does anyone know what is wrong and how to accomplish my goal? thanks, jb

Freeswitch locking up after reply for ERLang sofia.conf is sent

I'm sending back XML for sofia.conf from my ERLang code, but after the reply is sent, Freeswitch is locking up. It's only based on the template/default values for mod_sofia, but if I send the not found reply, Freeswitch locks up as well. Any ideas?

FreeSWITCH Documentation
by Muhammad Shahzad 21 Sep '09

21 Sep '09

Hi, I have observed that one of the major hurdle while writing patches and / or bug fixes is lack of doxygen documentation for FS source code. For example it took me 5+ days to understand mod_dingaling code and its hooks into FS source code to write up soft reload patch, while it could have taken less then 3 days to do so if source code documentation was available. So, since right now i have some human resources including myself available, I would like to document all source code (or at least core FS code i.e. everything that has "switch_" prefix) using doxygen. I know its a huge task and will take a while to complete but at least lets get it started. If anyone else wants to participate as well in this task, then we can team up to complete it quickly. Let me know if you guys are interested. 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

multicast paging
by Robert Buchholz 19 Sep '09

19 Sep '09

I am new to freeswitch, and was experimenting with the multicast paging. I found that the TTL of 1 is a great limitation to what I am trying to do. I have modified the source code of mod_esf.c to allow the TTL to be modified as an argument like the IP and ports. I am submitting the diff file for comment and possible inclusion in future releases. I have tried to follow the format and style of programming. I have compiled and run this successfully on both FreeBSD 7.2 and Fedora 11. Please let me know what you think. Robert

Patch for soft reload command in mod_dingaling
by Muhammad Shahzad 19 Sep '09

19 Sep '09

Reference: http://jira.freeswitch.org/browse/LBDING-15 ======================================================================================================================= Here is new patch with all thread lock / unlock and memory management stuff etc. it does following, 1. Adds a new dingaling menu command, "dingaling reload". 2. While executing this command it re-reads XML configuration (from file or XML CURL, whichever configured). 3. Adds new profiles in configuration. 4. Deletes profiles that are no longer in XML configuration. 5. Checks all profiles which exist in both old and new XML configuration, verify that all parameters match. 6. If any parameter is not match then it deletes older one and loads newer one. 7. If no parameter mismatch found then it leaves the profile as is. 8. While deleting profiles, if any profile is in call, it does not drops the call, instead marks that profile for deletion and upon completion of call it deletes the profile. I have verified its functionality is all possible test cases (that we can think of) and found it consistent without any performance drawbacks. Kindly review and add this patch to mainstream. ======================================================================================================================= 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
