Hi folks, in mod_conference is it possible to for exemple select a 2 cam side by side but with let's say a zoom of the person taling more than 30 sec? Thanks Franck

EVS Codec module for FreeSwitch ?
by Marcel Haldemann 07 Jun '19

07 Jun '19

Hi guys, Is there any change to get an EVS-Codec (https://www.iis.fraunhofer.de/en/ff/amm/communication/evs.html) implementation in FreeSwitch ? EVS is the successor of AMR-WB and As far as I understand it's royalty free for Network Devices (only mobile phone and table manufacturers got to license it, at least for now, and if it changes it can be centrally licensed at mpegla.com) Quote: "EVS Network Devices o Royalties waived during the initial term" from: https://www.mpegla.com/wp-content/uploads/EVSWeb.pdf General Info: https://www.mpegla.com/programs/evs/ Some info from other sources: https://www.businesswire.com/news/home/20170627006588/en/MPEG-LA-Introduces… regards, Marcel

We have multiple sites that use call groups with the same configuration however, only one site is experiencing any issues. I'm relatively new to FreeSWITCH, so please let me know if there is additional information I can provide. Thanks in advance for any advice. The sites are using FreeSWITCH version 1.2.14 The Polycom phones are using version 3.3.5 Here is the issue I see in the PCAP: [image: Screen Shot 2019-05-24 at 5.55.56 AM.png]

having problems configuring source of master
by John Covici 01 Jun '19

01 Jun '19

Hi. I am having a problem configuring freeswitch master. I have libvpx-1.7.0 but I get the following complaint when running ./configure checking for v8-6.1_static >= 6.1.298... checking for v8fs_static >= 6.1.298... checking for v8 >= 6.1.298... configure: error: You need to either install libv8-6.1-dev (>= 6.1.298), libv8fs-dev (>= 6.1.298) or disable mod_v8 in modules.conf Since I have 7.0 should not this work? Where is it looking for these files? I do have a pc file for this, but its called vpx.pc and had the information for libvpx package, so what am I missing? Thanks in advance for any suggestions. -- Your life is like a penny. You're going to lose it. The question is: How do you spend it? John Covici wb2una covici(a)ccs.covici.com

creating conferences
by Amit Chaudhuri 31 May '19

31 May '19

Hi, I am trying to create a conference using the fs_cli in order to experiment with the conferencing capabilities. I can issue a 'conference list' command and get (as expected) a message confirming I have no active conferences. I can also issue 'conference xml_list', 'conference commands', 'conference help' and get sensible answers. When I try 'conference dial sofia/3001 12345 test' for example, I get a message: "Conference dial not found". Is it possible to create a conference from the cli? In particular, is it possible to create an empty conference that users can dial into at a later point in time? I've not found any examples which help me, although I have seen an unresolved bug report - FS11133 - that might imply one cannot create empty conferences. Any help appreciated. Regards, Amit

sched_api survive restarts
by Bipin Patel 31 May '19

31 May '19

hi, is it possible to make sched_api tasks persistent and survive restarts, i want to create a wakeup call scenario where the admin sets a time and all extensions in a group are called at that time and played a sound file and admin can change time at will. I looked at a few lua scripts but mostly all make use of the sched_api and i noticed they dont survive a FS restart -- Regards, Bipin

refusing t38 in outgoing fax server transmission
by Sandro Bordacchini 30 May '19

30 May '19

Hello everyone. I am have a few FS installations interconnected with a voip provider; during outbound fax server transmissions, they told us that we need *to refuse T38 even if offered by the network*. The sdp offer/answer negotiation varies depending on the called number, probably due to a different routing in the voip provider's network. I experience some dropped calls (even before the fax transmission kicks in) using both FS versions 1.4.9 and 1.6.16. This is a successful sdp negotiation (after call is estabilished) First reinvite: REMOTE INVITE with SDP: v=0..o=LucentPCSF 413445855 413445856 IN IP4 10.198.1.230..s=-..c=IN IP4 10.198.1.230..t=0 0..m=audio 15756 RTP/AVP 8 96 4..a=rtpmap:96 telephone-event/8000..a=fmtp:96 0-15..a=ptime:20..a=X-sqn: 0..a=X-cap: 1 image udptl t38.. LOCAL 200OK with SDP: v=0..o=FreeSWITCH 1558069426 1558069428 IN IP4 10.197.98.6..s=FreeSWITCH..c=IN IP4 10.197.98.6..t=0 0..m=audio 30394 RTP/AVP 8 96..a=rtpmap:8 PCMA/8000..a=rtpmap:96 telephone-event/8000..a=fmtp:96 0-16..a=silenceSupp:off - - - -..a=ptime:20.. Then, a second reinvite happens: REMOTE INVITE with SDP: v=0..o=LucentPCSF 413445855 413445857 IN IP4 10.198.1.230..s=-..c=IN IP4 10.198.1.230..t=0 0..m=audio 0 RTP/AVP 0..c=IN IP4 10.198.1.230..m=image 12834 udptl t38..a=X-sqn: 0..a=X-cap: 1 image udptl t38.. LOCAL 488 Then, the last reinvite: REMOTE INVITE with SDP: v=0..o=LucentPCSF 413445855 413445858 IN IP4 10.198.1.230..s=-..c=IN IP4 10.198.1.230..t=0 0..m=audio 15756 RTP/AVP 8 96 4..a=rtpmap:96 telephone-event/8000..a=fmtp:96 0-15..a=ptime:20..a=X-sqn: 0..a=X-cap: 1 image udptl t38..m=image 0 udptl t38..c=IN IP4 10.198.1.230..

And the fax is transmitted correctly This is an unsuccessful sdp negotiation: First reinvite REMOTE INVITE with SDP: v=0..o=LucentPCSF 579041281 579041282 IN IP4 10.198.1.230..s=-..c=IN IP4 10.198.1.230..t=0 0..m=audio 13302 RTP/AVP 8 96..a=rtpmap:96 telephone-event/8000..a=ptime:10..a=ecan:fb on -..a=Fax..m=image 17522 udptl t38..a=T38FaxVersion:0..a=T38MaxBitRate:14400..a=T38FaxRateManagement:transferredTCF..a=T38FaxMaxBuffer:1800..a=T38FaxMaxDatagram:260..a=T38FaxUdpEC:t38UDPRedundancy..a=ecan:fb on -.. LOCAL 488 and the remote hangs up. My point is that, in case of unsuccessful negotiation, FS receives a reinvite with two "m=" in the sdp, one G711A (port 13302) and one T38 (port 17522). Is it ok for FS to refuse "all the sdp" with 488 just because it has to refuse T38 or it should be configured to refuse only the T38 media? Should remote endpoint send another reinvite with only G711 or only T38 before hanging up? Thanks in advance to whoever read till here :-) Any hints? S. P.s.: This is what i get in the log in the unsuccessful case during the reinvite (1.4.9 code): [...] 2019-05-17 11:22:57.498389 [DEBUG] switch_core_media.c:3476 Audio Codec Compare [PCMA:8:8000:10:64000:1]/[PCMA:8:8000:10:64000:1] 2019-05-17 11:22:57.498389 [DEBUG] switch_core_media.c:3531 Audio Codec Compare [PCMA:8:8000:10:64000:1] ++++ is saved as a match 2019-05-17 11:22:57.498389 [DEBUG] switch_core_media.c:3397 Set telephone-event payload to 96 2019-05-17 11:22:57.498389 [DEBUG] switch_core_media.c:3713 Set 2833 dtmf send payload to 96 2019-05-17 11:22:57.498389 [ERR] sofia.c:7065 Reinvite Codec Error! 2019-05-17 11:22:57.498389 [DEBUG] switch_core_session.c:1053 Send signal sofia/external/<calledfaxnumber> [BREAK] 2019-05-17 11:22:57.498389 [DEBUG] switch_core_session.c:1053 Send signal sofia/external/<calledfaxnumber> [BREAK] 2019-05-17 11:22:57.498389 [DEBUG] switch_core_media.c:2280 Already using PCMA 2019-05-17 11:22:57.498389 [DEBUG] sofia.c:6444 Channel sofia/external/<calledfaxnumber> entering state [ready][488] 2019-05-17 11:22:57.638443 [DEBUG] switch_core_session.c:1053 Send signal sofia/external/<calledfaxnumber> [BREAK] 2019-05-17 11:22:57.638443 [NOTICE] sofia.c:952 Hangup sofia/external/<calledfaxnumber> [CS_EXECUTE] [NORMAL_CLEARING] 2019-05-17 11:22:57.638443 [DEBUG] switch_channel.c:3222 Send signal sofia/external/<calledfaxnumber> [KILL] 2019-05-17 11:22:57.638443 [DEBUG] switch_core_session.c:1388 Send signal sofia/external/<calledfaxnumber> [BREAK] 2019-05-17 11:22:57.638443 [DEBUG] mod_spandsp_fax.c:293 FLOW T.30 Status changing to 'The call dropped prematurely' This are the most relevant settings on api originate: [DEBUG] switch_event.c:1688 Parsing variable [fax_use_ecm]=[off] [DEBUG] switch_event.c:1688 Parsing variable [absolute_codec_string]=[PCMA@10i] [DEBUG] switch_event.c:1688 Parsing variable [fax_enable_t38]=[false] [DEBUG] switch_event.c:1688 Parsing variable [fax_enable_t38_request]=[false] [DEBUG] switch_event.c:1688 Parsing variable [refuse_t38]=[true] and on the external profile t38-passthru is set to false. -- Ing.
