FreeSWITCH Weekly News and Notes
by Michael Collins 20 May '13

20 May '13

Hello! The FreeSWITCH team is busy on several fronts but the most exciting news at the moment is that Packt Publishing has told us the new book<http://www.packtpub.com/freeswitch-1-2/book>is officially off to production! If all goes well it should be available in the next few weeks. (It looks like they changed the cover art - once we know for sure what's on the cover we'll give it a nickname like we did with the "bridge" book.) Last week we had an impromptu discussion<http://wiki.freeswitch.org/wiki/FS_weekly_2013_05_15>on various FreeSWITCH topics. We have rescheduled the VoIPMonitor.org conference call presentation for May 29th. Also, we have tentatively scheduled the HOMER presentation for June 5. That means we will have another open discussion<http://wiki.freeswitch.org/wiki/FS_weekly_2013_05_22>for this Wednesday's conference call. As a tip, if you would like to browse around and see what has been committed in FreeSWITCH lately you can use the Fisheye site<http://fisheye.freeswitch.org/>. Here you can browse the source code and look at recent commits to see what has changed. If you prefer to look at the commits without the source code browser then try out the HTML front-end <http://fisheye.freeswitch.org/>for our FreeSWITCH git repository. We also have repositories for contributions <http://git.freeswitch.org/git/freeswitch-contrib/> and sample configuration <http://git.freeswitch.org/git/freeswitch-sample-configs/>sets. Have a great week! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

VAD Events stop Firing after Bridgine
by Rony Beck 20 May '13

20 May '13

Hi All, I have a problem with Voice Activity Detection. I am writing a module which will bridge a call to a conference when it detects voice activity on the line. When voice activity isn't detected for a period, the call is parked until voice activity is detected again. It seems that before the call is bridged to the conference, Voice Activity Detection works fine and events with the "Action" of "start-talking" or "stop-talking" are fired. Once the call is bridged, these events are no longer fired. Even If I manually park the call from fs_cli using "uuid_park", the events with "start-talking"/"stop-talking" are never fired again. I have been scouring the net looking for a means of getting these events to fire again. The sip profiles involved all have VAD enabled in both directions. In code, I start the conference call like so: sprintf(szCommand,"{TALK, NOTALK}sofia/externalx/confuser@%s:5080",szConfAddress); switch_ivr_originate( NULL,&pPersistentSession,cause,szCommand, iTimeout, NULL,NULL,NULL,NULL,NULL, SOF_FORKED_DIAL,NULL ) != SWITCH_STATUS_SUCCESS; pMainSessionUUID = switch_core_session_get_uuid( pPersistentSession ); pPersistentChannel = switch_core_session_get_channel( pPersistentSession ); pAppName = switch_core_session_strdup( pPersistentSession, "conference" ); sprintf(szCommand,"%s@default",pExtension); pAppOpt = switch_core_session_strdup( pPersistentSession, szCommand); pPersistentCallExtension = switch_caller_extension_new(pPersistentSession, pAppName, pAppOpt); switch_caller_extension_add_application( pPersistentSession, pPersistentCallExtension, pAppName, pAppOpt ); switch_channel_set_caller_extension( pPersistentChannel, pPersistentCallExtension ); switch_channel_set_state( pPersistentChannel, CS_EXECUTE ); This is just calling another freeswitch box which answers the call and keeps the conference open. I then make a second call to the user's sip phone in much the same way. sprintf(szCommand,"{TALK, NOTALK}user/1001"); switch_ivr_originate( NULL, &pUserSession,&cause, szCommand, iTimeout,NULL,NULL,NULL,NULL,NULL, SOF_FORKED_DIAL,NULL ); pUserSessionUUID = switch_core_session_get_uuid( pUserSession ); pUserChannel = switch_core_session_get_channel( pUserSession ); pUserAppName = switch_core_session_strdup( pUserSession, "conference" ); sprintf(szCommand,"%s@default",USER_EXTENSION); pUserAppOpt = switch_core_session_strdup( pUserSession, szCommand); pUserCallerExtension = switch_caller_extension_new(pUserSession, pUserAppName, pUserAppOpt); switch_caller_extension_add_application( pUserSession, pUserCallerExtension, pUserAppName, pUserAppOpt ); switch_channel_set_caller_extension( pUserChannel, pUserCallerExtension ); switch_channel_set_state( pUserChannel, CS_EXECUTE ); At this point the events are firing fine and my event handler is reacting to them. On the first "start-talking" event I get from the user, I bridge the calls like so: switch_ivr_uuid_bridge (pMainSessionUUID,pUserSessionUUID); At this point, the events for "start-talking" or "stop-talking" are no longer fired and are never fired again even if I break the bridging. I tried commenting out the bridging line just to be sure that the events are fired without the briding and it looks fine. I get all the events continuously. So it seems to break as soon as I bridge. To capture the events, I had expected that I should bind to the events like this: switch_event_bind("START_TALK_EVENT", SWITCH_EVENT_TALK, SWITCH_EVENT_SUBCLASS_ANY, detect_talk , NULL); switch_event_bind("END_TALK_EVENT", SWITCH_EVENT_NOTALK, SWITCH_EVENT_SUBCLASS_ANY, detect_talk , NULL); This never worked. What did work was this: switch_event_bind("TALK_EVENT", SWITCH_EVENT_CUSTOM, "conference::maintenance", detect_talk , NULL); My event handler would just look for an event where the "Action" was set to "start-talking" or "stop-talking". Is there something I am missing here? I don't find enough information on the wiki to help me work out exactly how VAD events should be listened for and handled, so it is entirely likely I am doing it wrong. Can someone help me here or event paste a working code sample? Many thanks for your time, Ronnie

Commit access for Nathan
by Mathieu Parent 16 May '13

16 May '13

Hi, As main developer of mod_skinny, I request commit access to Nathan who has proposed several patches to mod_skinny recently. I think this is a good way to improve the mod_skinny development by shortening integration time. Nathan will start by asking review from me (or core devs). Once he is confident enough, he can directly commit. Regards -- Mathieu Parent

14 May '13

A belated happy new week to you all! As Ken mentioned in his email yesterday<http://lists.freeswitch.org/pipermail/freeswitch-users/2013-May/095530.html>, the big news from last week is, of course, the release of FreeSWITCH 1.2.9 stable. This is now the "latest stable" version of FreeSWITCH and the one most recommended for production use. The tarball<http://files.freeswitch.org/freeswitch-1.2.9.tar.bz2> is available from theusual location <http://files.freeswitch.org/>. The CentOS and Debian packages have also been updated to use the latest stable. On last week's conference call<https://wiki.freeswitch.org/wiki/FS_weekly_2013_05_08> we welcomed Dan from the CGRateS project <http://www.cgrates.org/>. CGRateS is a relatively new project that handles call rating for carrier-grade operations. We are happy to have CGRateS (an open-source project itself) as part of the FreeSWITCH ecosystem. On this week's call <https://wiki.freeswitch.org/wiki/FS_weekly_2013_05_15> we look at another VoIP-related OSS project: VoIPMonitor.org<http://voipmonitor.org/>. This software performs a number of monitoring functions for VoIP implementations. Please join us tomorrow at 1PM EDT, 10AM PDT for an interesting discussion. One ClueCon reminder: We are still accepting speaking proposals, however time is running out so please send them in as soon as possible. We hope to have the ClueCon 2013 schedule released in the next few weeks. Take care and have a great week! -- Michael S Collins Twitter: @mercutioviz http://www.FreeSWITCH.org http://www.ClueCon.com http://www.OSTAG.org

Happy first May Monday to all. We are please to let everyone know that the new FreeSWITCH book<http://www.packtpub.com/freeswitch-1-2/book>is nearing completion. Each day the Packt editors have been sending us revised and re-revised chapters to polish off. If we keep up our current pace then it is quite likely the book will be available in early June. We hope you enjoy it. On last week's call <http://wiki.freeswitch.org/wiki/FS_weekly_2013_05_01>we enjoyed a nice presentation from Omar over at OrecX <http://www.orecx.com> who showed us some of the useful features of their call recording solutions. They have an open source version as well as commercial versions. If you are looking for a call recording solution then we recommend that you review what OrecX has to offer. This week <http://wiki.freeswitch.org/wiki/FS_weekly_2013_05_08> we continue in our series of presentations on FreeSWITCH-compatible software applications. We look forward to having Dan Bogos from CGRateS<http://www.cgrates.org/>join us to talk about their project. Click here <http://cgrates.readthedocs.org/en/latest/introduction.html> to get a quick look at what CGRateS does, and then make plans to join our call on Wednesday. Regarding ClueCon 2013 we would like to remind everyone that we are still accepting talk proposals. If you have a talk idea please let us know. In the meantime feel free to get registered <http://cluecon.com/register/> and book your hotel room at the Hyatt.
