New Debian FS vanilla install fails
by Sean Devoy 04 Mar '20

04 Mar '20

HI all, I have a new Debian 8.1 (32 bit) server for testing. I first did an apt-get install curl then per the instructions here: https://freeswitch.org/confluence/display/FREESWITCH/Debian+7 I did this: echo "deb http://files.freeswitch.org/repo/deb/debian/ `lsb_release -sc` main" >> /etc/apt/sources.list.d/freeswitch.list curl http://files.freeswitch.org/repo/deb/debian/freeswitch_archive_g0.pub | apt-key add - apt-get update apt-get install freeswitch-meta-vanilla It runs for less than a minute and dies at: Setting up freeswitch-sysvinit (1.4.19~10~1-1~jessie+1) ...

See 'systemctl status freeswitch.service' and 'journalctl -xn' for details. invoke-rc.d: initscript freeswitch, action "start" failed. dpkg: error processing package freeswitch-sysvinit (--configure): subprocess installed post-installation script returned error exit status 1 Setting up freeswitch-systemd (1.4.19~10~1-1~jessie+1) ... dpkg: dependency problems prevent configuration of freeswitch-init: freeswitch-init depends on freeswitch-sysvinit (= 1.4.19~10~1-1~jessie+1); however: Package freeswitch-sysvinit is not configured yet. dpkg: error processing package freeswitch-init (--configure): dependency problems - leaving unconfigured and ends shortly with: Errors were encountered while processing: freeswitch-sysvinit freeswitch-init E: Sub-process /usr/bin/dpkg returned an error code (1) I ran the cmds it says: systemctl status -l freeswitch.service * freeswitch.service - freeswitch Loaded: loaded (/lib/systemd/system/freeswitch.service; disabled) Active: failed (Result: start-limit) since Wed 2015-06-17 17:11:15 EDT; 18min ago Jun 17 17:11:15 fstest.devoy.us systemd[1]: freeswitch.service: control process exited, code=exited status=1 Jun 17 17:11:15 fstest.devoy.us systemd[1]: Failed to start freeswitch.

What am I missing? Sean

Stumped by mod_portaudio permissions issue
by Mark Haun 02 Feb '20

02 Feb '20

I built freeswitch version 1.7.0+git~20150730T192909Z~ab7f83c654~32bit for my ARM-based home server (an NVIDIA Jetson board), with the intention of using mod_portaudio with a wireless USB headset for my main home phone. It works well when running freeswitch directly as root, but when I configured freeswitch to run at system startup, mod_portaudio could no longer find any audio devices. No problem, I thought, it's a simple permissions issue. I am using the example debian init script from the wiki (this is a Jessie install with SysV init rather than systemd). It runs freeswitch as user freeswitch, group daemon using the -u and -g command-line options. So I added "freeswitch" to the audio group, then used sudo to verify that I could play sound files with "aplay" as the freeswitch user. That worked, but it did not solve the mod_portaudio failure. Thinking there must be an issue with portaudio separate from ALSA, I fetched and built the "pa_devs" utility which enumerates and prints the available audio devices. (This is basically what mod_portaudio is doing on startup.) Running as the freeswitch user, that worked too. Hmmmm. I tried running freeswitch from the command line using sudo rather than the -u and -g options, i.e. $ sudo freeswitch /usr/local/freeswitch/bin/freeswitch -nc and that worked as well! Then I started experimenting with -u and -g and discovered that $ /usr/local/freeswitch/bin/freeswitch -nc -u freeswitch allows mod_portaudio to load correctly, whereas $ /usr/local/freeswitch/bin/freeswitch -nc -u freeswitch -g daemon causes mod_portaudio to fail. Can anyone explain what's happening here? In both cases the process UID, GID, EUID, EGID, FUID, and FGID are the same (freeswitch:daemon) as displayed with "ps xao pid,uid,gid,euid,egid,fuid,fgid". Could this be a bug in freeswitch? There are a couple of threads from 2-3 years ago in the archives, where mod_portaudio permissions issues were never resolved and the solution remained a mystery. For the time being I guess this (not using -g) is a workaround, but I'd sure like to understand what is going on. Mark

Call transfer
by Moshe Rosenberg 12 Apr '19

12 Apr '19

Hi With the old Panasonic system there was a feature that if we transfer a caller to an ext and the person does not answer it will not go to VM instead it would ring back to the user who tried to transfer the call How can we do that? In freeswitch

FS dev communication channel
by Harangozó, László 28 Mar '19

28 Mar '19

What is the "standard" dev communication channel these days? I have read the Community chapter <https://freeswitch.org/confluence/display/FREESWITCH/Community> from the docs but I am still confused. - The freeswitch-dev(a)lists.freeswitch.org list seems inactive (signed up 9 days ago, no traffic since) - The #freeswitch-dev on IRC seems also abandoned as the topic was set more than 4 years ago (whatever that means, I have never used IRC before) - The #freeswitch-dev channel on Slack is active, but I am not sure if this is the primary channel (as searching the history costs money) I have added a couple of features locally and would like to discuss how and what to contribute back.

Video across loopback
by Dave Singer 27 Mar '19

27 Mar '19

I'm using loopback for connecting calls in some situations but it seems that I can't get video to work when I use a loopback. The SIP captured on both inbound and outbound legs of the call set up the video fine with the 200 OK to the INVITE containing the proper SDP for H264 and the RTP for the video is getting to Freeswitch but not going out from freeswitch. T he logs that seem relevant... mod_loopback.c:158 loopback/<ext>/context-a setup codec G7221/32000/20 then a little further down switch_ivr_originate.c:1273 Raw Codec Activation Success L16@32000hz 1 channel 20ms 0_23453543(a)192.168.88.221 2019-03-20 21:49:28.564575 [DEBUG] switch_core_codec.c:223 sofia/sipinterface_1/<ext2>@<realm> Push codec L16:100 Those are for audio but there are none for video. Is video not supported by loopback? I'm on Freeswitch 1.6.20.1 Thanks Dave

Chrome M76 requires DTLS 1.2, doesn't work with FS 1.6 on Debian 8
by Thomas Auge 27 Mar '19

27 Mar '19

FYI for those still using FS 1.6 with webRTC clients: Chrome will require DTLS 1.2 starting with M76, which does not appear to work with FS 1.6 on Debian Jessie. Compiling with backported OpenSSL 1.0.2 did not help. https://freeswitch.org/jira/browse/FS-11730 Cheers! Thomas
