Lync and Openfire Integration
by Vinay V 01 Feb '13

01 Feb '13

Hi All, We are in process of integrating Microsoft Lync with Openfire (Ignite Realtime). Using the default procedure documents available in the Google to do the same did not help us to accomplish it. *Default procedure like using Microsoft XMPP gateway.* * * *My present test lab is having 2 Microsoft Domain Controllers.* * * *Two domain controllers are smart.lab and test.lab. * * * *Domain controller smart.lab contains MS LYNC 2010.* * * *Domain controller test.lab contains Openfire.* * * *MS Lync edge is having two nics (one internal and one external) and it’s not joined to domain. MS OCS XMPP GW 2007 R2 server is having one nic and even this is not joined to domain.* * * *Tried a lot but was not successful.* After browsing a lot in Google came across Freeswitch application which will help us to proceed further. Through the blogs came to know that XMPP servers can be integrated with Freeswitch. As I am new to this this tool, unable to understand the concepts. If any anybody have tried integrating Lync with Openfire using Freeswitch are requested to provide me the inputs (Docs/URL) to proceed further. Thanks & Regards * Adarsh P M*

problems with freeswitch + zrtp in proxy-media mode
by Eli Burke 01 Feb '13

01 Feb '13

I'm trying to use Freeswitch with an open source voip client called Linphone, but cannot manage to establish functioning ZRTP sessions. The problem *seems* to be related to the RTP stream's SSRC. I'm trying to conclusively determine if the problem lies with Linphone, Freeswitch, or one of the underlying zrtp implementations (libzrtp and zrtpcpp). Here's what I've determined so far: 1) ZRTP support is compiled and functioning. I can establish ZRTP sessions between two iPhones running Groundwire. 2) linphone + ZRTP works correctly if I make a one legged call to a Freeswitch echo extension 3) linphone + ZRTP works correctly if I turn on bypass-media 4) linphone gets a CRC error when trying to verify the ZRTP packet on any two-legged call 5) disabling the CRC check results in a successful ZRTP session, but the audio is extremely garbled Is Freeswitch modifying the ZRTP packets when running in proxy mode? If so, how is it that some clients are able to handle this situation? Thanks for any suggestions, Eli

Hi, Am trying to install ICTFAX. As per this site ictfax-20-installation-guide<http://ictfax.org/content/ictfax-20-installation-guide> I followed the instructions.

Create a symbolic link for /usr/ictfax in /var/www/html ln -s /usr/ictfax /var/www/html/ictfax ln: creating symbolic link `/var/www/html/ictfax': No such file or directory.

Tweaking end_pointing on mod_conference
by Usama Zaidi 01 Feb '13

01 Feb '13

Hey Hi, I wanted to know if there's a way to tweak audio end-pointing on mod_conference, the duration of speech/silence it waits for before throwing out a speaking/stopped speaking event, and not just the energy-level. Thanks. -Usama -- I'd love to change the world, but they wont gimme the source code to it

Non-numeric extension - bad idea?
by Steven Schoch 31 Jan '13

31 Jan '13

We have a main number and extensions, but some people have their own DID number that rings on line 2 (of a 2-line Polycom phone), with a separate voice mailbox. This "line 2" is not supposed to be an extension, so in its directory entry, I have the "effective_caller_id_number" set to the DID number. I don't want this line to be a real extension, so I set the user id to be a descriptive short name, not a number. Is this a bad idea? The problem is that it's impossible to check voice mail on that line because the user can't dial the user id. Would it be better to use the 10-digit number as the user id? Or should I use an extension number that starts with a different digit? That would solve the voice mail problem as well, because the dialplan passes the caller-id to the voicemail check application. -- Steve

Execute app in sync mode when using event sockets
by Hector Geraldino 31 Jan '13

31 Jan '13

Hi, I have a java app that uses mod_event_socket (inbound mode) to control FreeSWITCH. I can send api commands which, by default, are synchronous, so the thread locks until the command is successfully executed. The problem I'm facing is when I have to execute commands that are in other modules (like playback, or speak). As they are not api commands, I must send an execute appName + arguments, which by nature is executed in async mode. What I want to achieve is to execute an speak command and wait until the TTS operation ends (blocking the thread). This sounds like a trivial use case: play some audio (TTS, file) and then execute the rest of the logic. It is easy to accomplish on the dialplan, but I just can't figure out how to do it on an ESL application. Here's what I've tried so far: + send execute speak command + api sleep and wait for the CHANNEL_EXECUTE_COMPLETE (to simulate a lock [sleep] and continue [break after event is received]), but the event arrives after the sleep command completes. + use uuid_broadcast uuid speak::args, doesn't work Any hints, ideas are welcomed. Thank you! Hector

Recording / concurrent calls and performance
by Malay Thakershi 31 Jan '13

Hello, Does recording audio sessions slow down performance of concurrent calls / FreeSwitch? I am doing: application="record_session" in the dial plan before transferring the call to managed DLL. Thanks for help.

Routing inbound call to multiple extentions
by Todd Bailey 31 Jan '13

31 Jan '13

Hi All, At witt's end on this, how do I get a inbound call to go to multiple extension? I've tried groups but so far no avail I using a spa 3102 as a analog adapter that is configured to rout calls to extension 1000, I want FS to automatically forward this call to extensions 1001-1009. Here is an extract from default.xml (/usr/local/freeswitch/conf/directory) <group name="frontoffice"> <users>  <user id="1001" type="pointer"/> <user id="1002" type="pointer"/> <user id="1003" type="pointer"/> <user id="1004" type="pointer"/> <user id="1005" type="pointer"/> <user id="1006" type="pointer"/> <user id="1007" type="pointer"/> <user id="1008" type="pointer"/> <user id="1009" type="pointer"/> </users> </group>

ZRTP Cache file location on FreeSWITCH fixed/updated
by Ken Rice 31 Jan '13

31 Jan '13

Hey Guys, If you have noticed theres been an issue with ZRTP enabled FreeSWITCH where ZRTP keeps a cache of hashs identifying previously contacted ZRTP endpoints. (This is part of the mechanism to help detect Man in the Middle attacks). Prior to today that cache file was being improperly named ! And was being dropped in the Directory FreeSWITCH was being ran from. Travis Cross and I got a patch together today and it has been pushed into tree. Starting today the file has been moved over to the proper FreeSWITCH db directory (/usr/local/freeswitch/db on default from source installs) with the name zrtp.dat . If you are currently using this functionality, you can keep your cache around by moving it to the new location. (ex: # cd /usr/local/freeswitch && mv \! db/zrtp.dat ) This patch is currently only in master, but will be rolled into the pending stable updates. Thanks for the help Travis!

Re: [Freeswitch-users] Postgres in the Core

I guess my main question is do the other modules accept the new postgres:// syntax or do I still need to use odbc for those? > -- > Andrew Cassidy BSc (Hons) MBCS > http://www.jonisdumb.com/ > > -- *Andrew Cassidy BSc (Hons) MBCS SSCA* Managing Director *T <info(a)cassidywebservices.co.uk> *03300 100 960 *F<info(a)cassidywebservices.co.uk> *03300 100 961 *E <info(a)cassidywebservices.co.uk> *andrew(a)cassidywebservices.co.uk *W <info(a)cassidywebservices.co.uk> *www.cassidywebservices.co.uk
