by Magnus Kelly 03 Mar '18

03 Mar '18

Hello all, Due to mail bounces temporally removing me from the mailing list, I may have missed news on the potential 1.8 release. I see the development branch now moved to 1.9, but can't see any info on next stable release to match the Packt Publishing book I'm just reading and enjoying. Tip of the hat to to Anthony, Giovanni and the Freeswitch team. Thanks Magnus

Conference mux mode video flickering
by Dom Rumsey 03 Mar '18

03 Mar '18

Hi guys Thanks for your help previously. I'm now using MUX mode for video and I'm getting a problem whereby a conference with 3 or more participants keeps flickering video streams on the floor (we are using video-muxing-personal-canvas parameter). It's as if it can't decide who to show. Below is my conference profile: <profile name="cp"> <param name="domain" value="$${domain}"/> <param name="rate" value="8000"/> <param name="video-mode" value="mux"/> <param name="video-layout-name" value="1x1"/> <param name="interval" value="20"/> <param name="caller-controls" value="default"/> <param name="energy-level" value="0"/> <param name="video-auto-floor-msec" value="3000" /> <param name="video_no_video_avatar_png" value="/usr/local/freeswitch/conf/images/video-muted.png" /> <param name="video_mute_png" value="/usr/local/freeswitch/conf/images/video-muted.png" /> <param name="conference-flags" value="audio-always|livearray-sync|livearray-json-status|video-mute-exit-canvas|video-muxing-personal-canvas"/>  <param name="max-members" value="25"/> <param name="sound-prefix" value="/usr/local/freeswitch/conf/sounds/"/> <param name="enter-sound" value="tone_stream://%(200,0,500,600,700)"/> <param name="exit-sound" value="tone_stream://%(500,0,300,200,100,50,25)"/> <param name="inbound-late-negotiation" value="false"/> </profile> Any pointers on where I'm going wrong would be really appreciated. Thank you

Best way for storing Media for Freeswitch
by Emrah Ciftcibasi 03 Mar '18

03 Mar '18

Hi, I need a solution to store and read media files from Freeswitch servers (I have multiple Freeswitch). Media files are recorded voicemails, recorded calls and user files like welcome sounds, IVR sounds, waiting music, etc. Currently this is solved by using a mount to a SMB share (NFS) on local storage. This works good but I think it has a drawbacks like it is not scalable.. I wonder, what kind of solution exist in the literature ? What are the best practices that you face? Best Regards, Melek P.S. At first a solution with a distributed file system was tried with GlusterFS. This had some drawbacks, especially with high latency synchronization between nodes. This approach was dropped.

javascript scheduling multiple events excecute_on_answer
by Francesco Facco de Lagarda 01 Mar '18

01 Mar '18

I am developing a calling platform using javascript. I have code that calculates how long THAT user is allowed to call THAT number for. I am trying to schedule 2 events, 1. 1 min before time ends, that plays a message "you have 1 minute left .." 2. The actual hangup when the time expires.. Despite a zillion tests I have been unable to schedule BOTH events.. This is my code: for simplicity's sake I have set call time to 120 secs, with warning at 60: if (session.ready()) { /*** Get user, number, etc. code omitted for simplicity **/ var sessOut = new Session("sofia/gateway/ht503/" + dialedNum + "@192.168.0.201:5062"); var totTime = 60; sessOut.execute("set", "execute_on_answer=sched_hangup +120 alloted_timeout") sessOut.execute("set", "execute_on_answer=sched_broadcast +60 playback::" + soundDir + "one_min_left.wav both"); if (sessOut.ready()) { bridge(session, sessOut); } sessOut.hangup(); session.hangup(); }

Fax Transmit Rate - force to 9600?
by Andrew 01 Mar '18

01 Mar '18

Hi all, We've been trying to get our fax implementation as reliable as possible using FS; we've had some great results with inbound faxes with the following items set in the incoming dial-plan: action application ="answer"/> action application="playback" data="silence_stream://2000"/> action set ignore_early_media=true action set absolute_codec_string='PCMU,PCMA' action set fax_enable_t38=true action set fax_verbose=true action set fax_use_ecm=true action set disable-v17=true action set fax_v17_disabled=true action set fax_disable_v17=true action set fax_enable_t38_request=true application rxfax /tmp/FAX-IN-${uuid}.tif application hangup The one thing that we have identified with this configuration is that 99% of inbound faxes come through fine when the fax transfer rate is negotiated at 9600 bps (as a result of the fax_v17_disabled=true setting). However, we still see quite a few incoming faxes reported as coming in with a fax transfer rate of 14400 bps, which have a 100% fail rate. I understand that the two ends need to negotiate a rate; but how do we force (or only offer) the rate of 9600 or lower? My understanding is that the fax_v17_disabled=true setting should cover that? My first thought was that the remote end was forcing the rate at 14400, regardless of what we were sending back in terms of fax capabilities. Not sure if it helps, but the two error messages we receive when faxes fail due to the 14400 rate are: - Unexpected DCN while waiting for DCS or DIS, and - The call dropped prematurely My thought was, If we could find a way to get all faxes coming in at 9600, we'd be able to improve the reliability. Looking through the wiki and previous list messages, the fax_disable_v17=true setting seems to be the documented approach, but I'm not sure why we're still seeing faxes come in at a higher rate. Any advice on this or are we missing something with regards to locking in the lower speed? cheers, A

Cdr files not using correct template in master.csv but does if use separate files
by Joseph Waite 28 Feb '18

28 Feb '18

Hi Guys Im wondering if I’m missing something or if this is expected behaviour? I have 3 different templates and i’m using account code variables in my dial plan to tell FS to use a specific template for certain calls. If I have master-only set to true then it ignores the templates and all cdr’s use the default template. If I disable master-only, all cdr’s are written to master.csv and all use the default template, however I also get a file for each account code and this contains only the cdr’s for that account code and they use the correct template. Surely all cdr’s should use the template that matches the account code if there in the master or not? Im just wanting to check this before I file a Jira. FreeSWITCH Version 1.6.19+git~20171025T192126Z~86184a2f73~64bit (git 86184a2 2017-10-25 19:21:26Z 64bit) I have not tried on latest Master. Regards

BLF on Yealink (public "ping" to Kevin Wormington).
by Bob Smith 28 Feb '18

28 Feb '18

Hi, I've sent this to list just incase anyone else wants to chip in. I Googled up an old post from Mr Wormington (August 16 2013 @ 16:09, subject "BLF"). In it, Kevin describes how he has encountered behaviour with Yealink where the BLF remains green despite the subject of the BLF being no longer registered. There seems to have been very little in public follow up to Kevin's post at the time, so I was wondering if anyone could enlighten me as to what the solution is, because I am facing the same quandry. Thanks ! Bob
