[Freeswitch-dev] Rtcp-mux and mod_dingaling
by Richard Screene 18 Feb '13

18 Feb '13

Hello, Does mod_dingaling support rtcp-mux? If not can anyone suggest the best way for me to add this functionality? I'm only really interested in receiving the RTP and RTCP on the same port (I don't need to have FreeSWITCH send them on the same port). Many thanks, Richatd

[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 18 Feb '13

18 Feb '13

Greetings all! Last week was rather interesting. Initially we had planned on doing a CudaTel <http://www.cudatel.com> demonstration on the weekly conference call. However, interest in Eliot Gable's mod_ha_cluster<http://wiki.freeswitch.org/wiki/Mod_ha_cluster>and the accompanying conversation<http://lists.freeswitch.org/pipermail/freeswitch-users/2013-February/092187…>was particularly intense. That being the case, on last week's conference call <http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_13> we spent most of the time talking about HA in general and how we could build a FreeSWITCH HA system. We also invited everyone who is interested in the subject to call in to the public FreeSWITCH conference at 8PM EST on Tuesday evening (Feb 19) for the first HA conference call. (Eliot won't join until about 8:15PM.) If you have a vested interest in HA for FreeSWITCH then please join the conference call. For this week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_20>we will ask one of the participants on the Tuesday night call to give us a brief overview of the HA discussion. After that I will be doing a demonstration of the CudaTel to show off what the FreeSWITCH team has been working so hard to develop these past few years. We hope you enjoy it! For the DIY crowd you may enjoy this site <http://switchpi.org/> that Ken Rice set up. It's dedicated to doing cool things with FreeSWITCH and the Raspberry Pi <http://www.raspberrypi.org/>. Check it out! In ClueCon <http://www.cluecon.com>2013 news we are getting things all set. In the coming days we will be making announcements about new sponsors, registration and hotel information, and a call for speakers for this year's event. Don't forget to plan for a full 3 days, August 6th - 8th. Also, we tend to do a lot of fun stuff on the Monday before ClueCon, so it's a good idea to arrive on or before Monday August 7. Hope you have a great week! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

[Freeswitch-dev] Odp: Integration of FreeSWITCH and Open IMS
by Mariusz Czulada 18 Feb '13

18 Feb '13

Hi Anindo, We have FSW servers integrated with an IMS platform (ALU is the vendor). They play the role of MRF (media announcements and ivr/conferences), but not as strictly as in 3GPP docs (no MRFC/MRFP splitting). We have only Mr interface towards S-CSCF and Mb to MGWs. No Mr, no Rf. Is this what you plan to do to, or you want to build a full AS (like BroadWorks) in the IMS application layer?

[Freeswitch-dev] Change Voicemail IVR Menu
by Muhammad Shahzad 18 Feb '13

18 Feb '13

Hi, I am trying to change menu order of FS voicemail module. I am using voicemail_ivr with xml_curl, when a voicemail user checks voicemail, i check if user has his own greeting set, then play normal voicemail menu, otherwise instead of playing message count and related options, i simply want to play voicemail preferences menu, in fact only voicemail record greeting menu. I have tried many different possibilities including many changes to voicemail_ivr.xml and voicemail_ivr.conf.xml but so far none worked. FS Wiki on voicemail_ivr module seems outdated. Till now i am only able to play standard voicemail menu through voicemail_ivr module. Do I have to modify native code of these modules (mod_voicemail and mod_voicemail_ivr) to achieve the goal? Any suggestions / guidelines? P.S. Note that sample files (voicemail_ivr.conf.xml and voicemail_ivr.xml) do not work as is, i had to modify many typos and tag attributes to get it working same as standard mod_voicemail works. I will update wiki once this problem is solved.

[Freeswitch-dev] question about CNG on late packages
by Xijing Dai 16 Feb '13

16 Feb '13

Hey all, Inside code switch_rtp.c file: static int rtp_common_read(switch_rtp_t *rtp_session, switch_payload_t *payload_type, switch_frame_flag_t *flags, switch_io_flag_t io_flags) ................ if (check || (bytes && !switch_test_flag(rtp_session, SWITCH_RTP_FLAG_USE_TIMER))) { if (!bytes && switch_test_flag(rtp_session, SWITCH_RTP_FLAG_USE_TIMER)) { /* We're late! We're Late! */ if (!switch_test_flag(rtp_session, SWITCH_RTP_FLAG_NOBLOCK) && status == SWITCH_STATUS_BREAK) { switch_cond_next(); continue; } return_cng_frame(); <------- this lane to return cng frame if late. } } Could someone explain why we want to return cng frame when package is late? this is caused for me to hear very bad noise audio. Can I disable return CNG frame? Cheers

[Freeswitch-dev] FreeSWITCH HA BoF Meetings
by Michael Collins 14 Feb '13

14 Feb '13

Hello! Yesterday we had a nice discussion <http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_13>about all things HA. Eliot Gable gave us a lot of very good information about the state of mod_ha_development and all the work that he's done over the past 4+ years in the world of HA and FreeSWITCH. It's now time to let those who have a vested interest in HA to get together with Eliot and continuing the discussion. To that end we propose a FreeSWITCH HA BoF (Birds of a Feather) conference. Eliot says that he can be available after 8PM EST. I would like to propose that the meetup be Tuesday evenings at 8:00PM EST in the main FreeSWITCH public conference. If you would like to meetup then please email me off-list and CC Eliot ( egable+freeswitch(a)gmail.com) so that we can keep track of who is most interested in this topic. Thanks! -- Michael S Collins Twitter: @mercutioviz http://www.FreeSWITCH.org http://www.ClueCon.com http://www.OSTAG.org

[Freeswitch-dev] Event engine like FreeSWITCH
by Eduardo Nunes Pereira 14 Feb '13

14 Feb '13

Hi, folks this topic it's a little bit off-topic, i just want to know if there is an event engine written in C/C++ like FS's event socket system, that you can register your application and fire and listen internal events binding with app our by network. When i was programming for iOS i seen something similar with NSNotificationCenter. -- Eduardo Nunes Pereira skype: eduardonunesp msn:eduardonunesp http://about.me/eduardonunesp

[Freeswitch-dev] Dingaling does not retain payload IDs
by Richard Screene 12 Feb '13

12 Feb '13

Hello, When FreeSWITCH receives a Jingle session-initiate message containing a Opus codec with a payload type of 111, it will respond with a session-accept. But the session-accept will assign the payload type for Opus to 116. For example: 2013-02-12 10:44:52.543318 [INFO] libdingaling.c:1747 RECV: ... <jin:jingle xmlns:jin="urn:xmpp:jingle:1" action="session-initiate" initiator="Richard(a)127-0-0-1-852145229.xmpps.drum-collab" sid="3441545841"> <content creator="initiator" name="audio"> <description xmlns="urn:xmpp:jingle:apps:rtp:1" profile="RTP/SAVPF" media="audio"> <payload-type id="103" name="ISAC" clockrate="16000"></payload-type> <payload-type id="104" name="ISAC" clockrate="32000"></payload-type> <payload-type id="111" name="opus" clockrate="48000"></payload-type> <payload-type id="0" name="PCMU" clockrate="8000"></payload-type> … 2013-02-12 10:44:52.543318 [NOTICE] libdingaling.c:1749 SEND: ... <jin:jingle xmlns:jin="urn:xmpp:jingle:1" action="session-accept" sid="3441545841" initiator="Richard(a)127-0-0-1-852145229.xmpps.drum-collab"> <jin:content name="audio" creator="initiator"> <rtp:description xmlns:rtp="urn:xmpp:jingle:apps:rtp:1" media="audio" ssrc="2585956684"> <rtp:payload-type id="116" name="opus" clockrate="48000" ptime="48000" maxptime="48000"> <rtp:parameter name="bitrate" value="32000"></rtp:parameter> </rtp:payload-type> ... From my reading of XEP-0167 (Section 5) it would appear that FreeSWITCH should retain the payload ID that was present in the session-initiate and use it in the session-accept. Is there a config flag to control this behaviour? Is it intentional behaviour? Or is it a bug? I could hack the payload type in the Opus module but we have another endpoint that insists on using a completely different payload type ID. Many thanks, Richard
