G.711.0
by Steve Underwood 12 Mar '11

12 Mar '11

Hi, Has anyone seen G.711.0 in real world use? The spec was published quite a while ago, but as far as I can tell there is no RFC defining the SDP and RTP details needed to deploy it, and nobody advertises that they support it in their products. Steve

It had been a while I didn't get a chance to upgrade my FS git until today. With a newly built FreeSWITCH Version 1.0.head (git-0f7682a 2011-02-25 21-06-22 +0100), at least a new problem surfaces where FS Segmentation fault as shown below: 2011-02-25 21:30:34.277865 [CONSOLE] switch_core.c:1764 _____ ______ _____ _____ ____ _ _ | ___| __ ___ ___/ ___\ \ / /_ _|_ _/ ___| | | | | |_ | '__/ _ \/ _ \___ \\ \ /\ / / | | | || | | |_| | | _|| | | __/ __/___) |\ V V / | | | || |___| _ | |_| |_| \___|\___|____/ \_/\_/ |___| |_| \____|_| |_| ************************************************************ * Anthony Minessale II, Michael Jerris, Brian West, Others * * FreeSWITCH (http://www.freeswitch.org) * * Paypal Donations Appreciated: paypal(a)freeswitch.org * * Brought to you by ClueCon http://www.cluecon.com/ * ************************************************************ 2011-02-25 21:30:34.278007 [CONSOLE] switch_core.c:1767 FreeSWITCH Version 1.0.head (git-0f7682a 2011-02-25 21-06-22 +0100) Started.

session:record / prevent DTMF tones from being recorded
by Matt Stockton 11 Mar '11

11 Mar '11

Hi all, I have a freeswitch lua script that is recording and I want the recording to be terminated when the user presses the '#' key. That is all working fine for me, but the recording always has the DTMF tone at the end of it. I am wondering, is there a way to instruct freeswitch to not record the DTMF tones? Any help is appreciated. For reference, here are some excerpts from my lua script: function inputHook(s, type, obj) freeswitch.consoleLog("INFO", "On input"); if (inRecording and type == "dtmf" and obj['digit'] == '#') then inRecording = false; return "break"; end end ..... session:setInputCallback("inputHook", ""); ..... session:recordFile(recordFilePath, 202, 500, 25); Thanks in advance

Call back from voice mail creates loop
by Tim St. Pierre 11 Mar '11

11 Mar '11

Hello, I'm trying to set up the option in voicemail so that users can return a call directly from VM. In my voicemail.conf.xml profile I have specified the dialplan as XML and the context as "internal", which is what I use for calls coming from our endpoints or authenticated users. In our internal dialplan, we do some pattern matching and call an appropriate lua dialplan script to do build a set of instructions. Problem is, the lua scripts are looking at the destination_number variable to decide where to send the call. This variable is still set to "voicemail" from when the user called into their voicemail. Shouldn't the voicemail app have set that to the number we want to call back? I used the info app to look at the variables, and I didn't see anything obvious. Is destination_number the correct variable to use in a lua script that generates a dialplan? -Tim

Internal extensions placing call on hold drops immediately
by Mario G 11 Mar '11

11 Mar '11

I don't know when this started but was working fine at one time. If a call is made between extensions and either extension places the call on hold, it states "trying to hold". I installed the git from 3/9/11 before posting here. Could this be a Sofia problem (see FREEPBX comment) or something that FS needs to "setup" the phone to work since it works fine using a different PBX? Any help appreciated! * The phones are Linksys SPA962 * If I plug the old SPA9000 in as a PBX hold works fine for the SPA9000 extensions, only FS has the issue * All connected via HP Procurve 2520G switch * Outside calls are also affected but this is still a problem even with the router disconnected * I can ping (ICMP) from FS to the phone and from anywhere to the phone FS TRACE: I started several FS traces: sip global,internal, log 9 console debug, etc. It looked like NOTHING was sent when the hold button was pressed. WIRESHARK showed these messages stacking up when the hold is pressed src 1.123.1.23 (phone) dest 1.123.1.7 (FS) Proto ICMP Destination unreachable (Port unreachable) Someone updated FREEPBX in FEB 2011 and had the same issue with SPA phones. http://www.freepbx.org/forum/freepbx/users/spa-941-942-drop-call-when-place…

Strange Behavior with Channel Variable [session:setVariable() vs <action application="set" ... /> ]
by Sidharth Kshatriya 11 Mar '11

11 Mar '11

Dear All, I am using a little known but very useful channel variable called "playback_timeout_sec" In Lua if I do: session:setVariable("playback_timeout_sec", "10") and subsequently in a macro I have: <action function="play-file" date="/some/filename.mp3" /> Then the filename.mp3 stops playing automatically after 10 seconds. This is very useful if you want to play short excerpts of a file that could be very long. But if I do: <action application="set" date="playback_timeout_sec=10" /> <action function="play-file" date="/some/filename.mp3" /> My file does NOT stop playing after 10 seconds. This is weird given that <action application="set" .. /> is doing exactly the same thing as session:setVariable() ... right? My question 1. What could be the problem with application set? 2. Is there a way to automatically stop playback after a certain number of seconds for a file? (without doing tedious things like create a separate 10second version of an mp3 using ffmpeg etc.) Thanks, Sidharth -- Sidharth Kshatriya www.sidk.info

Working configuration for FS behind NAT?
by GillesToo 11 Mar '11

11 Mar '11

Hello I'd like to set things up, where... - FS and local SIP extensions are on a private LAN behind a NAT firewall, - remote employees are allowed to register with Freeswitch so they're part of Freeswitch, - none of the routers support UPnP or NAT-PMP, and - to lower load on the Freeswitch server, I'd like to have RTP packets flow directly between extensions instead of going through Freeswitch, like Asterisk does with its "canreinvite=no" option. However, Freeswitch should remain in the loop somehow so that users can access PBX features during their call. Here's the picture: http://img577.imageshack.us/img577/1795/freeswitchnat.png Apparently, changes to Freeswitch made http://wiki.freeswitch.org/wiki/General_NAT_example_scenarios this page obsolete. If Freeswitch can do this, does someone have a basic, working configuration that I could use to get started? Thank you. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Working-configuration-for-FS-… Sent from the freeswitch-users mailing list archive at Nabble.com.

British sounds
by Alex Crow 11 Mar '11

11 Mar '11

Does anyone know of either of the following: 1. A source (paid or free) of British English sounds (preferably female voice) for Freeswitch, preferably covering all the same sounds as those supplied. or 2. A script to convert and rename sounds from an Asterisk install to FS? We already paid for British female sounds for Asterisk so if conversion will cover at least voicemail prompts it would be a start.

tones.conf parameters?
by Johan Helsingius 11 Mar '11

11 Mar '11

Hi! Trying to use freeTDM with FreeSWITCH, but the supplied tones.conf only has setups for US, SG and RU. I found the ones for India on the wiki, but haven't found anything for NL (that I need), nor any other European country. Any pointers to how to configure tones.conf for NL? Any way to use stuff from asterisk? Julf

Error! cannot get read lock
by Laurentiu Ceausescu 11 Mar '11

Hi, I have the following dialplan: <extension name="line1"> <condition field="destination_number" expression="^333$"> <action application="answer"/> <action application="set" data="allow_voicemail=true"/> <action application="set" data="queue=Queue"/> <action application="set" data="brand=110011"/> <action application="playback" data="/usr/local/audio/welcome.wav"/> <action application="set" data="domain_name=$${domain}"/> <action application="erlang_sendmsg" data="freeswitch_media_manager toor(a)127.0.0.1 inivr ${uuid}"/> <action application="erlang" data="freeswitch_media_manager:! toor(a)127.0.0.1"/> </condition> </extension> When I call 333 I can hear welcome message but then the call is dropped. FS logs shows this error: [ERR] handle_msg.c:56 Error! cannot get read lock.

This thing is happend only after I updated to last git head (419d7e2335042e2d86c678c0daf86c2d9c867036 /Mar 9). With a older revision (e88b9639624cef4f35901146241f515730b3b118 /Jan 31) everything works fine. Any idea what has been changed? Thanks, Laurentiu
