dynamic music on hold for mod_conference
by Lappe, Adam 19 Mar '20

19 Mar '20

Hi all, i am trying to dynamically set the mod-sound variable in mod_conference, so I can play different music on hold to my conference rooms without having to create multiple profiles. Is there a way to set my moh-sound path while I create the conference? Or can I change the moh-sound file via the event socket in a existing conference? I think this would also lead to success. Thanks in advance, Adam

New Debian FS vanilla install fails

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

mod_sms questions
by Sean Devoy 13 Aug '19

13 Aug '19

Hi, I have found information on mod_sms to be limited. Our provider (Voip Innovations) supports SMS on our DIDs. Here is their document explaining handling options. https://backoffice.voipinnovations.com/Wiki/View.aspx?article=SMS Our client is using Bria Softphone (on Android and iPhone). I assume this is to mask her true cell phone number/identity. Can FreeSwitch route incoming SMS messages on DIDs to specific extensions/registrations? And route from an extension out? Any documentation hints would be greatly appreciated. Thanks, Sean

Transcoding Bandwidth parameters

Hi, I've noticed when transcoding freeswitch sets a default max bandwidth to 1mb (b=AS:1024). Why is this? And is this configurable?

rtmp streams sometimes take 4+ sec to start
by David P 30 Jul '19

30 Jul '19

Can you suggest ways we could investigate slow rtmp streams? We stream them to another machine in the same cluster, and send a POST just before, but the stream often arrives 4-10 seconds after the POST. At minimal load conditions
