"barge in" implementation with mod_socket and eavesdrop
by Artem Shiyanov 17 Sep '09

17 Sep '09

Hello! I'm trying to implement "barge in" functionality (see http://www.yourdictionary.com/telecom/barge-in) with "eavesdrop" but still with no success. The situation is: - Person A calls to the extension: <extension name="some_ext"> <condition field="destination_number" expression="^900.$"> <action application="answer"/> <action application="park"/> </condition> </extension> - I bridge him with person B with help of mod_socket: SendMsg <some_uuid> call-command: execute execute-app-name: bridge execute-app-arg: <person B address in form: "user/..."> - A and B talks - Person C decides to barge in the call A<-->B (to become a third participator in the call) a) I send (mod_socket): SendMsg <C_uuid> call-command: execute execute-app-name: eavesdrop execute-app-arg: <A_uuid or B_uuid, result is the same> b) Then, as the spec says ( http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop) I sent DTMF "3" with api uuid_send_dtmf <C_uuid> 3 but it doesn't work. I mean that A can hear B and vice verse, but both A and B can't hear C. C also doesn't hear neither A nor B. If I press "3" on the C's softphone (latest X-Lite) then, really, C becomes a full-capabilities participator of the call. Instead of "uuid_send_dtmf" I tried: 1) sendevent DTMF Unique-ID: <C_uuid> DTMF-Digit: 3 DTMF-Duration: 2000 2) first make queue_dtmf for the <C_uuid>, and then eavesdrop 3) SendMsg <C_uuid> call-command: execute execute-app-name: gentones execute-app-arg: 3 4) SendMsg <C_uuid> call-command: execute execute-app-name: send_dtmf execute-app-arg: 3 And none of these methods leads to the "barged in" call. Anyone knows how to press "3" programmatically on behalf of the given channel with mod_socket?! Artem

Please Help: TDM Hardware For Testing
by Michael Collins 17 Sep '09

17 Sep '09

Hello all! We could use your help with something. We've had several volunteers willing to assist with testing and debugging various scenarios with TDM circuits. However, there is a need to get TDM hardware into the hands of those volunteers. If you have old TDM hardware, be it analog or digital, that is sitting around collecting dust and you'd like to donate it (or loan it) to the cause then please email me off list. Thanks! -MC

mod_conference performance
by Роберт Тверитнер 17 Sep '09

17 Sep '09

Hi guys! I've tested FreeSWITCH conference module performance trying to figure out maximum number of simultaneous calls my FS box can serve. It took all 100% of CPU with only 50 calls (in average depending on conference rate) and "leaking stream handle" messages started appearing. The environment I was testing in: OS - Windows Server 2007 SP1 64 Bit CPU - Dual-core AMD Opteron 1216 HE 2.4 GHz RAM - 2 GB FreeSwitch version 1.0.4 (14460) I've written a test program that used to originate calls once in 5 seconds from the other box. These calls were routed to particular conference room I was testing. I had a number of rooms with different rate (8000-32000) and interval (20,30) settings and with perpetual-sound turned on steraming music continiously. I've switched off all unnecessary modules, but left logging on in order to trace what was happening later. Client test softphone used respective speex codec according to conference room rate. This is a dialplan I used: <extension name="test_conference"> <condition field="destination_number" expression="^(800020)$" break="on-true"> <action application="conference" data="$1@default20"/> </condition> <condition field="destination_number" expression="^(800030)$" break="on-true"> <action application="conference" data="$1@default30"/> </condition> <condition field="destination_number" expression="^(1600020)$" break="on-true"> <action application="conference" data="$1@wideband20"/> </condition> <condition field="destination_number" expression="^(1600030)$" break="on-true"> <action application="conference" data="$1@wideband30"/> </condition> <condition field="destination_number" expression="^(3200020)$" break="on-true"> <action application="conference" data="$1@ultrawideband20"/> </condition> <condition field="destination_number" expression="^(3200030)$" break="on-true"> <action application="conference" data="$1@ultrawideband30"/> </condition> </extension> My questions are: Do you know any way I can increase my FS conference capacity? What do I have to tune in FS or in my box? Best regards, Robert.

Re: [Freeswitch-users] 480 Temporarily Unavailable/503 Max Sessions (was 502 Bad Gateway: Destination out of order error)
by email lists 17 Sep '09

17 Sep '09

Anthony, I increased the ulimit parameters as suggested. I then ran into a few other Freeswitch errors that required me to edit switch.conf.xml to increase the max sessions, and max sessions per second parameters (to 100000, and 100, respectively). Now, after a few minutes of running calls at 20 calls per second with a 3 min. duration, I start seeing an influx of "480 Temporarily Unavailable" SIP error messages.

session record does not for very short calls
by Frank ＠ Impact 17 Sep '09

17 Sep '09

FreeSWITCH Version 1.0.trunk (12790M) I have this in my DP <action application="set" data="RECORD_ANSWER_REQ=true"/> <action application="set" data="RECORD_STEREO=true"/> <action application="record_session" data="/mnt/rd/file.wav"/> works fine as long as the call is long enough. But if the call is only, say, 3-4 seconds long (or something very short like that), then the wav file is never created with the audio in it. Is there a work around for this?

FreeSWITCH and OpenBTS integration
by Alberto Escudero 17 Sep '09

17 Sep '09

I am happy to let you know that FreeSWITCH route calls from OpenBTS, the open base station based on the Universal Software Radio USRP. Yes! Calls from a standard handset to a GSM base station connected to FreeSWITCH If you want to read more about the idea check: http://openbts.sourceforge.net/ http://www.it46.se/entry/380 (our effort to deploy the technology in a developing region) I have put a few notes for others to give it a try available here: https://sourceforge.net/apps/trac/openbts/wiki/OpenBTS/SettingUpFreeSWITCH Let me know what is the best place in FreeSWITCH wiki to add and keep updated this information -- Stopping junk mailers is good for the environment

I've been digging, but there doesn't seem to be a whole lot of information on faxing. I guess I could use a bit of direction. Any input is much appreciated. Thanks! -- Travis
