Issue with Enterprise originate and 487 "ORIGINATOR_CANCEL".
by Jai Rangi 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

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

Using turn relay in verto client
by António Silva 29 Dec '20

29 Dec '20

Hi, I want to share my experience with verto client and nat. I’m facing a delay issue with verto clients behind some types of nat (symmetric and port restricted cone nat), the port in the SDP is not the same for media and that introduces 3 seconds delay at the begging of the call. It only occurs in the direction Client -> Freeswitch. From the capture I notice that this delay is cause in the dlls negotiation, the Client Hello is sent to a port that is closed at the client side, after 3seconds FS detects that the rtp traffic is arriving in a natted port and it now send the Client Hello to that port. FS —> Client (pkt flow): 1s. Client Hello ——> :49897 <— (port unreached) 2s. Client Hello ——> :49897 <— (port unreached) 3s. Client Hello ——> :1025 <— Server Hello Certificate —> :1025 (Normal audio) Currently I solve it using turn server in the client and forcing to present only relay candidate to FS, DTLS is negotiated immediately, the only issue I see is that FS is not using the relay server (my configuration), it communicates directly to the client so it detects the change of address during media rtp: 1s. Client Hello ——> relay:49897 ——> client:49897 <— Server Hello:49897 FS RTP —> Relay: 49897 ——> client:49897 FS <— RTP from client address: 49897 (FS detects address change, stop send it to relay address and with to client address) FS RTP —> client:49897 The address change detection is perfect in this situation, we only load the relay server for dtls negotiation, then the media flows directly between FS and Client. What do you think of this approach? Do you have a better solution for this problem? -- Saludos / Regards / Cumprimentos António Silva

Calls dropping due to SDP change
by Nicola von Thadden 28 Dec '20

28 Dec '20

Hi, I'm currently investigating reproducable call drops when calling mobile-phone numbers from Deutsche Telekom (T-Mobile Germany). My provider has a NGN (SIP) Interconnection with Deutsche Telekom and is transparend for the messages involved here (although IP rewriting is happening). The calls contain following SDP in the invite from my FreeSwitch towards my provider: v=0 o=FreeSWITCH 1608967203 1608967204 IN IP4 *redacted* s=FreeSWITCH c=IN IP4 *redacted* t=0 0 m=audio 32256 RTP/AVP 9 8 0 101 a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 Once the call is established, FS sends a re-invite after 50% of the expiration timer is elapsed, 15 minutes in this case. The re-invite contains a slightly modified SDP: v=0 o=FreeSWITCH 1608967203 1608967204 IN IP4 *redacted* s=FreeSWITCH c=IN IP4 *redacted* t=0 0 m=audio 32256 RTP/AVP 8 101 9 0 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=rtpmap:9 G722/8000 a=rtpmap:0 PCMU/8000 a=ptime:20 The new codec on position 1 (PCMA) is not necessary the chosen one for the session, that call was using G.722 (verified via 'show channels'). Telekom does not like my SDP change and responds with: SIP/2.0 488 SDP Parameter Error In SIP Request The freeswitch console only logs: 2020-12-26 16:32:49.578925 [DEBUG] sofia.c:7326 Channel sofia/external/*redacted*entering state [calling][0] 2020-12-26 16:32:49.618925 [DEBUG] sofia.c:7319 Channel sofia/external/*redacted* skipping state [ready][488] The call is disconnected 15 minutes later because the session timer has expired: 2020-12-26 16:47:53.838925 [NOTICE] sofia.c:1089 Hangup sofia/external/*redacted* [CS_EXCHANGE_MEDIA] [NORMAL_CLEARING] This does not happen when I only allow PCMA (or any other codec) since the SDP can't get mixed up. I have reproduced that behaviour with 1.10.5~release~6~25569c1631~buster-1~buster+1 and 1.6.20~37~987c9b9-1~jessie+1. Do you have any idea why FS changes the SDP (without reason?) and what I can do about it? Thanks Nico

docker image
by Joli Martinez 28 Dec '20

28 Dec '20

Hello, Our company is pushing toward Docker now. That is the new focus for next year. Is there a Freeswitch Docker image already available? I searched on Dockerhub and could not find one. If there is not one avail. I was thinking of building one. I was planning on using the latest Debian base image and creating a Dockerfile with the installation of FreeSwitch. Is that the best approach or is there a better alternative? Also is there any reason not to Dockerize Freeswitch? Thanks,

Rings Versus Seconds
by KitchM 24 Dec '20

24 Dec '20

The system appears to use seconds instead of rings to measure incoming call timing. Is that correct? If so, is there a way to change things to use number or rings instead? -- Sent from: http://freeswitch-users.2379917.n2.nabble.com/
