Faxing with FreeSWITCH
by bruce＠sqls.net 16 Mar '21

16 Mar '21

Hello! I'm working on setting up a FreeSWITCH/Flowroute fax server. The server is connected without any nat on a 20MB fiber internet connection. I've built some lua scripts that allow me to receive and send faxes and log all the faxes to a sqlite database. I even have a management script that can be called from the fs_cli to add fax2email routes and adjust settings. It's still a pretty rough implementation but overall it's working fairly well but I have two main questions that I hope someone could help me with. 1) I would like to detect "voice calls" or maybe I want to detect fax calls? There's a dialplan function to listen for and detect a fax caller but I'm having trouble implementing it in my lua script. It seems it's a non-blocking function, maybe? Because it just walks right over that line instead of waiting and listening for any fax tones. I thought it would block the script for x seconds and listen for a fax tone and return a result based on what it found. Can someone help me accomplish something similar to that? 2) So far, by far... my most common error is "The call dropped prematurely". I'm not sure how to start debugging the error to figure out what's causing it and how (if I can) solve it. I do have pcap's of the calls from pcapsipdump and I also have the freeswitch log of each call (my lua script pulls and saves that for each fax call). I've opened the pcap files up in wireshark but I don't know what I'm looking for and I think that might be over my head at the moment. Can anyone give me any help on what this error is normally caused by or what I could look for and/or test? Here are a couple of example logs that ended with "The call dropped prematurely". http://bmts.us/faxlogs/FAX-2e913a50-3a4f-4abc-9882-a323a97e5138.log http://bmts.us/faxlogs/FAX-59d02d9d-c4ba-44c2-8edd-a1c9142c7c1c.log

Cron-like execution in FS
by Matthew Fong 10 Feb '21

10 Feb '21

I'm wondering if there's any features that allow the cron-like execution of code inside of Freeswitch, preferably with lua--or if I am stuck using the api interface and running the cron outside of freeswitch. --matt

mod_portaudio on Raspberry Pi currently broken?
by Lesley Pervis 27 Jul '20

27 Jul '20

I compiled mod_portaudio for rpi (arm11) in January. No problem. I compiled it again this week. Problem. Logs show it can't find any devices. So I copy the mod_portaudio.so and mod_portaudio_la from January to the newly compiled installation, and voila, devices found. I did a git diff in src/mod/endpoints/mod_portaudio, and there have been a couple of changes in the mod_portaudio.c file, but nothing that would explain this. Mod-portaudio source doesn't seem to have changed, just the way it's build. (Still version 1899, V19-devel.) The newer mod_portaudio.la shows different dependences, and the new mod_portaudio.so is much smaller. I think mod_portaudio is currently broken for raspberry pi and likely other platforms too. Anyone have any insight?

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

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

Change SIP Contact header on b-leg
by Кирилл Преслер 22 Feb '19

22 Feb '19

Provider not accepting calls because of "bad" Contact header sip:gw+ss@10.50.244.15:5060;transport=udp;gw=ss ITSP needs sip:username@10.50.244.15:5060, where username should be passed from dialplan for every call and there is no params. I've tried following variables with set and export, but nothing seems to work. sip_contact_user sip_outgoing_contact_uri sip_invite_contact_params

Re: [Freeswitch-users] stream a file multicast with mod_esf

Hi Brian, i thought if i can stream from portaudio it is almost the same with streaming from file, so it should working already now.
