Issue with Enterprise originate and 487 "ORIGINATOR_CANCEL".
by Jai Rangi 14 Jan '22

14 Jan '22

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

Odd RTP skew behavior
by Marc Bernard 12 Mar '21

12 Mar '21

Hello Peeps, I often notice the following behavior on calls between two FreeSwitch servers: https://contattafiles.s3.us-west-1.amazonaws.com/getinfinity/4WUXPK9ibKr018c /Pasted%20Image%3A%20Jan%2029%2C%202021%20-%2010%3A05%3A07am Telco <==> FS Node 1 <== X ==> FS Node 2 <==> Callee UA Caller UA <==> FS Node 2 <== X ==> FS Node 1 <==> Telco We're not doing proxy media or bypass media. There are other calls at the same time that does not have this behavior, so I doubt it is caused by network issues. Does anyone have an idea of what could cause this ? Appreciate any help. Most Kindly, Marc

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

users registering from IP or FQDN
by Joli Martinez 01 Feb '21

01 Feb '21

Hello, I am running a small freeswitch system with several phones, users register with the IP of the freeswitch box. Since they are now working from home more, they need to be able to connect remotely. I have built a kamailio proxy and exposed it. I created an FQDN sip.mydomain.com and pointed it to the kamailio box. The registration comes in and kamailio sends it to freeswitch. I have added my doemain underneath the internal sip profile like this. I have also reloaded it. <domain name="all" alias="false" parse="false"/> <domain name="sip.mydomain.com" alias="true" parse="true"/> Registrations from the public internet still fail, but users registering with the IP work. What am I missing? 2021-01-19 12:19:37.480591 [WARNING] sofia_reg.c:1794 SIP auth challenge (REGISTER) on sofia profile 'internal' for [222(a)Sip.mydomain.com] from ip 1.1.1.1 2021-01-19 12:19:37.540512 [WARNING] sofia_reg.c:2930 Can't find user [ 222(a)Sip.mydomain.com] from 1.1.1.1 You must define a domain called 'Sip.mydomain.com' in your directory and add a user with the id="222" attribute and you must configure your device to use the proper domain in its authentication credentials. 2021-01-19 12:19:37.540512 [WARNING] sofia_reg.c:1739 SIP auth failure (REGISTER) on sofia profile 'internal' for [222(a)Sip.mydomain.com] from ip 1.1.1.1

Scanners and botnet vulnerability
by Marc Bernard 01 Feb '21

01 Feb '21

Hello All, Is anyone else noticing that there is more and more scanners attempting brute force with no reply to auth request resulting in logging a lot of abandoned calls ? Scenario: - A scanner send an INVITE|REGISTER with no credentials - Freeswitch responds with authentication request and a challenge is send to logs; " 2021-01-25 12:27:39.306075 [WARNING] sofia_reg.c:1792 SIP auth challenge (REGISTER) on sofia profile 'public' for [1730(a)1.2.3.4] from ip 5.6.7.8" - Scanner does not respond - After a while, Freeswitch logs the following: 2ae23e93-c929-4089-a594-8e7af633ca88 2021-01-25 12:28:37.506078 [WARNING] switch_core_state_machine.c:687 2ae23e93-c929-4089-a594-8e7af633ca88 sofia/public/1730(a)1.2.3.4 Abandoned -- In our case, we made fail2ban more sensitive to auth failures logs which does not get triggered because of the scanner not even trying to send credentials. Wouldn't it make more sense for this log to include the IP of sip client that abandoned the call (5.6.7.8) instead of only the IP of the sip profile (1.2.3.4) ? This would allow us to have Fail2ban block this scenario more aggressively. Thoughts ?
