Multiple concurrent Verto calls in browser
by Michael Avers 05 Oct '18

05 Oct '18

Hello, I'm using Verto Communicator as a base for building a simple app to make/receive calls - and it works great. I'm trying to add the ability to manage multiple concurrent calls. My first thought is to create a new Verto service (in Angular) that maintains call state and reference to currently active call and otherwise keeps all calls in an array. Then to switch calls it'd place the currently active one on hold and then unhold any of the other calls in the array. Does this make sense? Any tips on handling multiple calls with Verto? Do I need a separate websocket connection for each? (they're all using the same proxy and credentials). Thanks! Mike

TLS SNI
by Andrew Cassidy 04 Sep '18

04 Sep '18

Hi Guys, I've seen this asked before but not answered, does FreeSWITCH support SNI in TLS? The main reason I ask is I have a customer having issues with the Let's Encrypt SAN certificate I have so am looking at getting a cheap paid one and installing that side-by-side.

Tagged v.1.8.1 - will there be pre-built packages, Debian 9/CentOS 7?
by Richard Chan 04 Sep '18

04 Sep '18

Looks like 1.8 is tagged starting at 1.8.1. Will there be pre-built packages distributed Couldn't see anything new in http://files.freeswitch.org/repo/deb/freeswitch-1.8 Also - I remember discussion about Debian Stretch issues(OpenSSL related). What is the current status of Stretch and is that supposed to be the reference platform for 1.8? Thanks @FreeSWITCH team! -- Richard Chan

mod_tts_commandline hangs in call flow
by Lee Vidor 31 Aug '18

31 Aug '18

Hi I'm currently using mod_tts_commandline with a python script to AWS text to speech API. The flow works fine during a single call. Event socket API -> Freeswitch dialplan -> mod_tts_commandline -> Python script -> AWS API -> Voice file -> Freeswitch say However when there a number of concurrent calls (even just 10 to 15) the request to execute the python script hangs until all the calls are at the same requesting state. As if mod_tts_commandline is waiting for something to happen. Dial plan: <extension name="tts_google"> <condition field="destination_number" expression="^11111$"> <action application="set" data="call_timeout=60" /> <action application="answer"/> <action application="detect_silence" data="100 30 25000"/> <action application="speak" data="tts_commandline|${lang}|${text}" /> <action application="hangup"/> </condition> </extension> tts_commandline.conf: <param name="command" value="/usr/bin/python /usr/local/freeswitch/scripts/synthesize_text.py --language=${voice} --filename=${file} --text=${text}"/> </settings> Execution of python script in freeswitch logs: 2018-08-30 11:19:57.641892 [ERR] switch_ivr_play_say.c:2385 switch_ivr_detect_silence: SILENCE DETECTED 2018-08-30 11:19:57.641892 [DEBUG] switch_core_codec.c:248 sofia/external/33123456789 Restore previous codec PCMU:0.

Trickle ICE
by Mirko Brankovic 30 Aug '18

30 Aug '18

Hi, I read a mailing thread from year or two back, about mod_verto and mod_sofia sharing a same media stack, and that implementing Trickle ICE would mean quite some work. I'm wondering if anyone started with this work or if it is already there? I see that right now SDP without any candidate is dropped by the media.c :) Thanks, -- Regards, Mirko

Re: [Freeswitch-users] wait_for_silence not working through external gateway
by Lee Vidor 30 Aug '18

After much trial and error issue is related to firewall settings. Opening ports 16384 - 32768 enabled silence detection to work as expected.
