Issue with Enterprise originate and 487 "ORIGINATOR_CANCEL".

All, Running into a small issue with group calling, when the original caller hang up, phones dont show that call as missed call, cause of wrong reason code from freeswitch. Scenario: - Caller -> FS (Groupcall) to 101 and 102 - Phones ring - Caller hangup - Phones should see missed calls, - But free-switch send cancel with Reason: SIP;cause=200;text="Call completed elsewhere", where is should send Reason: SIP;cause=487;text="ORIGINATOR_CANCEL". Here is what my bridge data. bridge(<all_threads=true,absolute_codec_string=PCMU,PCMA,G729,group_confirm_file=playback /usr/local/freeswitch/sound/ivr/1443458342.wav,group_confirm_key=exec>{sip_cid_type=rpid,ignore_early_media=true,originate_timeout=30}[leg_timeout=20 ]user/101@192.168.5.50:_:[ignore_early_media=true,leg_timeout=20 ]user/ 102(a)192.168.5.50) If I send bridge(<all_threads=true,absolute_codec_string=PCMU,PCMA,G729,group_confirm_file=playback /usr/local/freeswitch/sound/ivr/1443458342.wav,group_confirm_key=exec>{sip_cid_type=rpid,ignore_early_media=true,originate_timeout=30}[leg_timeout=20 ]user/101(a)192.168.5.50 Everything works fine. I see some old posts but no resolution. Freeswitch version on Debian 8.9 FreeSWITCH (Version 1.6.16 git 3da6bd0 2017-04-07 16:49:13Z 64bit) Any idea or suggestion for workaround? Jai

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

Full Trickle ICE via mod_sofia supported?
by Alexander Haugg 16 Dec '20

Hello, Currently I'm trying to implement the Full Trickle mechanism as described here https://tools.ietf.org/id/draft-ietf-mmusic-trickle-ice-sip-11.html Since I haven't succeeded so far, I have the following questions. Is Full Trickle supported via mod_sofia? If so, which settings or sip headers are required? Thanks Alex

Masking caller
by Lars Kiesow 03 Dec '20

03 Dec '20

Hi everyone, I'm trying to mask the caller_id_name in a FreeSWITCH dialplan to prevent the real phone numbers to show up in our conferencing software. Someone sent me the following lines: <action application="set" data="MASK=${system echo ${caller_id_name} | grep -o -P '.{0,4}$' | sed 's/^/xxx-xxx-/' }"/> <action application="set_profile_var" data="caller_id_name=${MASK}"/> While this works perfectly and does exactly what I want, I'm unsure about potential security risks. The caller_id_name ends up in a shell command after all and I'm wondering if someone could send a name like `; rm /*` (you get the idea). Is this safe? Is the caller_id_name sanitized? Is there a better way to do something like this? Best regards, Lars

Force Inband DTMF Reception
by Adrian Worutowicz 30 Nov '20

30 Nov '20

Hello, For incoming calls, I want to receive DTMF inband. FS receives INVITE and at certain stage sends 200 OK with a SDP section, which always contains : a=rtpmap:101 telephone-event/8000 (what means 'DTMF in RTP metadata'). Indeed the DTMFs come via RTP. I tried various FS configuration options to remove that line, without success. How to do it? How to tell a gateway to send DTMFs inband ? In advance thank you very, very much, Adrian.
