FS 1.8 Docker image
by Filipe Cunha 20 Dec '18

20 Dec '18

Hi all, I'm trying to create a docker image with the latest version of FreeSWITCH. But I'm not able to do it. These are the steps that I did to try to do it. 1. Download debian stretch image *docker pull debian:stretch * 2. Build FreeSWITCH from source code following the guide <https://freeswitch.org/confluence/display/FREESWITCH/Debian+9+Stretch> in confluence step by step. I follow the production version 3. The step 2 went very well, and then I follow the post-installation instructions <https://freeswitch.org/confluence/display/FREESWITCH/Debian+Post-Install+Ta…> and this was when it stop working. I set up owners and permissions and when I try to do the systemd I was not able to do it. I copied the file *cp /usr/src/freeswitch/debian/freeswitch-systemd.freeswitch.service /etc/systemd/system/freeswitch.service *the content of the file was not exactly the same as the one in the tutorial, so I copied the content of the file on the tutorial and replace it. And when I tried to do *systemctl deamon-reload* I got this error message, *Failed to connect to bus: No such file or directory*. After trying to find a solution online I found this answer on SO <https://stackoverflow.com/questions/39169403/systemd-and-systemctl-within-u…> Do you guys know if there is a solution for this problem? We plan to use the latest version of FreeSwitch in our production environment, but we have a normal linux server to do it, and the devops team got everything working fine, we only have this problem when we try to use docker. I'm trying to use docker so my team could test everything locally before pushing something to the test environment, so far we have been deploying our code to test environment to test our code 😖 I found this image <https://github.com/BetterVoice/freeswitch-container> that works fine in our local environment, but the version is 1.6.16. Is there any braking change between 1.8.2 and 1.6.16? My concern it that we start developing against an older version, and when we deploy to production it doesn't work, or maybe the latest version have a super useful command that we are not taking advantage of. We control FreeSWITCH mainly by events, we use java to do it. Thanks for the help, Filipe Cunha

Audio delayed for about 3sec.
by 王聡 20 Dec '18

20 Dec '18

Hey all, Today I moved my freeswitch server from VM to cloud server, but I found there has an audio delay on both caller and receiver for about 3sec in each call during call test. Is there any idea for this audio delay? Regards.

*the problem isnt freeswitch, but your event consumer isnt consuming the events fast enough. you should adjust your side of the equation.the event queue is what drives everything * Hi again, I think FreeSwitch core mechanism should not be blocked when user module consuming thread is not fast enough. Per-module event queue with multi-thread consumer thread mechanism could solve this issue, or something else (i don't know). Since user can add its module to the Freeswitch, s/he could not block core of freeswitch since its wrong action i think.

MOD_CALLCENTER cannot originate call to agent
by Chhorm Chhatra 19 Dec '18

19 Dec '18

Hi, Currently, I am experiencing a very weird behavior of mod_callcenter like the following: 1. after 4 to 5 mins of hearing the moh-sound, it started to randomly play media from the sound/music folder 2. MOD_CALLCENTER *can never bridge any call to the agent. It mostly says the user is not registered (although it's registered). Sometimes, it says no-answer but the agent never rings.* *Please kindly help me.*

transfer B-leg to a custom extension with execute_on_answer : fails
by Julien Terrasson 18 Dec '18

18 Dec '18

Hi everyone, I'm looking from advices on that issue : In the following scenario, where A & B are PSTN subscribers : STEP 1 : A call freeswitch, freeswitch answers and play an audio prompt. STEP 2 : when the prompt ends, freeswitch attempt to bridge A with B STEP 3 : B_answer. I set a no_local::execute_on_answer hook to park A and play B an audio prompt (warning message) when B_answer. But thuis is what happen when the bridge command is executed : CASE 1 : If the INVITE TO B is responded with a 183-SESSION_PROGRESS before the 200-OK, the execute_on_answer hook work as i expect (A is parked, B is played the audio prompt) CASE 2 : If the INVITE TO B is responded with a 200-OK, the execute_on_answer hook does not work as i expect (A is parked but hangup B with cause destination_out_of_order). >From the trace i can see that in CASE 1, B party is put in CS_EXCHANGE_MEDIA earlier than in CASE2 Would this be likely to create the problem ? Best Regards, Julien

One way audio case between FS and Chrome on WebRTC
by MARAND, Remi 12 Dec '18

12 Dec '18

Hello, I am trying to validate FS as a SIP to WebRTC Gateway in our lab environment. I started in middle October and have good result on it, but i cannot understand this One Way Audio trouble. I must thank the Freeswitch team and contributors for this very impressive work. FreeSWITCH Version 1.8.1-2-4f54cff36a~64bit (-2-4f54cff36a 64bit) On system: SMP Debian 4.9.110-3+deb9u6 (2018-10-08) x86_64 GNU/Linux Openssl version : OpenSSL 1.1.0f 25 May 2017 Chrome version: 69.0 (I tried with different version and with Firefox with the same trouble). The wss part is ok with sip.js and verto.js The Ice negotiation is ok, I use sometimes local networks and sometimes web, I have had to authorize networks in the candidate ACL and domain ACL (acl.conf.xml) The result is the same on both topology. DTLS negotiation is OK, and there is UDP streams between Chrome (or Firefox) and FS in both ways. There is no "audible" audio in the direction from FS to Chrome, the other direction is OK. The simplest test is to call the 5000 number from the Chrome client, I send you a paste bin and pcap trace for this call. Should you give me information element to progress on this, what is really mandatory in the sip_profile/internal.xml and external.xml files, and in directory/default/1000.xml for a WebRTC call ?? What should be the good options in fs_cli to see if the encryption of RTP packets is ok or not.. ? Do you think that I have to reinstall a Freeswitch from the current branch ? @IP for FS : 192.168.145.67 @IP for Chrome : 10.70.54.43 Link on the pastebin : https://pastebin.freeswitch.org/view/09a72087 I have a pcap on the same call that I can provide (3 Mb) if necessary..
