STUN usage with Freeswitch
by Claudio Álvarez 08 Sep '11

08 Sep '11

Hi all, I currently operate a publicly accessible stun server, which one of my FreeSWITCH instances operating on Amazon EC2 queries for proper SIP and RTP configuration. When I query the stun server from FS-EC2, I get the following: freeswitch@internal> stun 74.xx.xx.xx 184.xx.xx.xx:35087 Can anyone clarify what does the 35087 number port stand for? Thanks. Regards, -- Claudio Alvarez claudio(a)clickfono.com

One-way audio issue with attended transfer
by John Platts 07 Sep '11

07 Sep '11

We have been experiencing a one-way audio issue with attended transfer. The problem is that after an call is transferred through an attended transfer, the caller cannot be heard, but the caller can hear the voice of the person that the call is transferred to. Steps to reproduce the problem: 1. Dial into FreeSWITCH from an external phone. 2. Answer the call. One-way audio is not experienced here. 3. Press the Transfer button on the IP phone to initiate an attended transfer. 4. Dial the extension that the call is to be transferred to. 5. Allow the extension that the call is to be transferred to pick up the call. One-way audio is not experienced here. 6. Press the Transfer button to complete the transfer. The caller does hear audio from the person that the call is transferred to, but the person that the call is transferred to cannot hear the caller. The one way audio issue is occurring here. The attended transfer was performed from an extension on one SPA303 phone to an extension on another SPA303 phone. FreeSWITCH actually detects that the transfer is an attended transfer. Here are attachments that I have uploaded to pastebin: conf/dialplan/features.xml file: http://pastebin.freeswitch.org/17291 FreeSWITCH log, including the attended transfer: http://pastebin.freeswitch.org/17286 How do we get this one-way audio issue fixed?

mod_fifo to Voicemail if there's no "agents"
by Silvio Escher 07 Sep '11

07 Sep '11

Hi there, ive following in my public dp: <extension name="zentrale_fifo"> <condition field="destination_number" expression="^zentrale_fifo$"> <action application="set" data="fifo_music=intro_und_schleife.wav"/> <action application="answer"/> <action application="set" data="fifo_orbit_exten=zentrale_voicemail:30"/> <action application="fifo" data="zentrale_fifo in"/> </condition> </extension> <extension name="Zentrale"> <condition field="${sip_to_user}" expression="^0631680350$" break="on-false"/> <condition wday="2-6" hour="9-16"> # zeit geht bis 59 <action application="transfer" data="zentrale_fifo XML public"/> <anti-action application="answer"/> <anti-action application="sleep" data="1500"/> <anti-action application="playback" data="niemand_da_zeit.wav"/> <anti-action application="sleep" data="1000"/> <anti-action application="hangup" data="NO_ANSWER"/> </condition> </extension> and iam adding Members to the fifo at runtime ( during *extension or an daily reset by cron ) ./fs_cli -x "fifo_member add zentrale_fifo user/26" or ./fs_cli -x "fifo_member del zentrale_fifo user/26" Everything works fine beside the little issue that if theres no Member/Agent in the fifo - the Call is just also waiting 30 seconds till transfered to voicemail. I noticed that with fifo list zentrale_fifo iam able to get an Memberlist ( fifo count just shows me 0 Members - dunno why - bug ? ) - but iam unsure how to process further. Whats the ideal Solution to get an Caller directly to the Voicemail when no Member/Agent is in the called Fifo ? Best Regards, Silvio -- Silvio Escher omeco GmbH
