Re: [Freeswitch-users] MIKEY-Support

The hard part was getting the srtp seamlessly integrated into our RTP stack. We had 3 brands of phones to test with while implementing and this was was the only way they all supported. There is clearly a feud on how to exchange keys out there and we will end up implementing each of them as they become popular. As a developer, I can only implement what I have to test with. Do you know any devices that support MIKEY to test against? There is a LGPL libmikey out there so it's a strong possibility we can implement it as long as we have a test bed and some indication that it will be widely accepted and desired by people.

That is secure. Read section 8.3 again. "Thus, IT IS REQUIRED that MIME secure multiparts, IPsec, TLS, or some other data security service be used to provide message authentication for the encapsulating protocol that carries the SDP messages having a crypto attribute (a=crypto)." It does however say in 8.3 "When the communication path of the SDP message is routed through intermediate systems that inspect parts of the SDP message, security protocols such as [IPsec] or TLS SHOULD NOT be used for encrypting and/ or authenticating the security description." This can clearly be seen don't trust it if TLS isn't used end to end for the sip signaling channel. SDES seems to be the most widely used method at this point as you pointed out. I feel the security afforded by using SDES + TLS is way more than you'll ever get elsewhere.

Call Waiting not working!!!!!

25 Jan '08

Hi, I am working on Freeswitch@ rev 7309. I remember with earlier revision call waiting was working fine. But now on getting the second incoming call FXS is returning 502 (BAD gateway error). Was there any change on FXS side pertaining to number of calls allowed or something???

Newbie question: can Freeswitch create subconferences on-the-fly & let a moderator speak to all of them?
by Brian Burt 24 Jan '08

24 Jan '08

Short version: can Freeswitch create subconferences on-the-fly & let a moderator speak to all of them? Long version: We lead live experiential learning workshops, where we are constantly saying "get a partner and share about x" and then "now get in groups of 4/6/8" to share about that and then finally we come back to the "big room" where we take a few shares from the big group. In particular we would like to place participants in small groups where they interact with each other, but all groups can hear the facilitator. I'd like to do something similar over the phone, and am wondering if a programmer could fairly easily accomplish this in Freeswitch. It's critical that the presenter still be able to speak to everyone, even when they are in small subconferences. Thinking that Asterisk could do it, I wrote up some requirements below. They're definitely not all "must-haves". I heard from several Asterisk experts that the "one-way" nature of this requirement (subconference hears presenter but not the other way around) meant that Asterisk really wasn't suited for it. Below are the full requirements. Do people think they're do-able? Easily? What platforms would allow that, especially open-source? ps. If there's a video it's likely always simply the presenter delivering that. Ideally would have ability to connect with POTS but if this can be done in a computer-only method (is there still such a thing?) I'd still love to know about it. ---------------------------------------- -- ===================== Brian Burt, Founding Partner Financial Circles Empowerment in Community www.FinancialCircles.com 415-308-4258 mobile (best) 510-251-1189 office brianDELETE-ME(a)FinancialCircles.com ===================== - - - "Financial Circles teaches people to master money so that it serves their dreams.

'outbound' IVR with JavaScript - garbage collection issues
by tuhl＠ix.netcom.com 24 Jan '08

24 Jan '08

My application dials 100's of numbers, waits for user to answer, plays a .wav file, and waits for some DTMF. I'm using the Javascript interface to do all this now (actually it's a Perl script which launches JS by sending jsrun commands through the RPC XML interface). But at high call rates, I'm running into JS garbage collection issues fairly quickly. At 10 calls per second, after about 300 calls it looks like JS GC kicks in and runs for like 45 seconds, during which time I can't launch any more calls with JS (RPC XML accepts them, but then they are getting Q'd up inside the spidermonkey code, and eventually some of them fail because GC is taking so long, etc). Is JS the best way to do this application, and if so, any ideas how I workaround the GC? If not, what is the alternative (where I would still have access to the simple programming interface that JS gives me, as far as all the session. functions like waitForAnswer, streamFile, getDigits).

Re: [Freeswitch-users] 'outbound' IVR with JavaScript - garbage collection issues
by Anthony Minessale 24 Jan '08

looking at the C code in mod_spidermonkey I can see that session.originate and session.waitForAnswer/Media did not suspend the garbage collector. Most often, when the host system spidermonkey is embedded in calls something that will block in the C code we should use special code around it to disable garbage collection. It's sort of like a mutex only it's backwards where you want to unlock it while you do anything that blocks and re-lock it when you resume. Since these 3 function can delay execution of more javascript I added code to revision 7343 to do this. Please test. Also, even if it works, you can still be more efficient by doing what Mike suggested and use the new bgapi FSAPI call together with the originate FSAPI call to originate the call in the core then execute the script. bgapi originate {ignore_early_media=true}sofia/default/user(a)domain.com &javascript(myscript.js) This will launch your script with the session already created. If you omit bgapi the xmlrpc call will block until the call is established, if it's present it will run in it's own thread to establish the call and fire and event to indicate the results.

Re: [Freeswitch-users] Hello from Scotland - Python - error importing module
by Traun Leyden 24 Jan '08

You'll want to change your dialplan to <extension name="500"> <condition field="destination_number" expression="^500$"> <action application="python" data="test"/> </condition> </extension> and make sure you put your test.py script somewhere on the PYTHONPATH by: 1.

Hello from Scotland - Python - error importing module
by Steven Brown 24 Jan '08

24 Jan '08

Hi, I've previously had a lot of Windows based SIP/IVR expreience with a variety of technologies but am now looking at alternative architectures for some forthcoming projects so have been doing some evaluation on platforms for producing some IVR type solutions initially for inhouse hosting but longer term to scale possibly on Amazon EC2. I'm also interested in contributing to the project if I settle on Freeswitch. Initially speed of development / application tuning for new proof of concepts is critical and the combination of Freeswitch / Python seems to fit the bill (not withstanding my lack of significant experience with either) To test this out I have set up a box running CentOS 5, built Freeswitch (with mod python) and configured the switch. Freeswitch works great for SIP calls between wifi handsets, so far so good and a very painless set up, impressive ! Dialplan is modified as below, <extension name="500"> <condition field="destination_number" expression="^500$"> <action application="python" data="test.py"/> </condition> </extension> test.py as below (borrowed from WIKI) from freeswitch import * def handler(uuid): session = PySession(uuid) session.answer() console_log("INFO", "Hello, world\n") session.hangup("1") is in python2.5/site-packages as is freeswitch.py however an incoming call to 500 generates the following 2008-01-22 21:46:12 [DEBUG] mod_dialplan_xml.c:273 dialplan_hunt() sofia/default/1001@192.168.0.12:5060 State Change CS_RING -> CS_EXECUTE 2008-01-22 21:46:12 [DEBUG] switch_core_session.c:643 switch_core_session_signal_state_change() Kill sofia/default/1001@192.168.0.12:5060 [BREAK] 2008-01-22 21:46:12 [DEBUG] switch_core_state_machine.c:413 switch_core_session_run() sofia/default/1001@192.168.0.12:5060 Running State Change CS_EXECUTE 2008-01-22 21:46:12 [DEBUG] switch_core_state_machine.c:452 switch_core_session_run() (sofia/default/1001@192.168.0.12:5060) State EXECUTE 2008-01-22 21:46:12 [DEBUG] mod_sofia.c:185 sofia_on_execute() sofia/default/1001@192.168.0.12:5060 SOFIA EXECUTE 2008-01-22 21:46:12 [DEBUG] switch_core_state_machine.c:130 switch_core_standard_on_execute() Standard EXECUTE 2008-01-22 21:46:12 [DEBUG] switch_core_state_machine.c:144 switch_core_standard_on_execute() sofia/default/1001@192.168.0.12:5060 Execute python(test.py) 2008-01-22 21:46:12 [NOTICE] mod_python.c:86 eval_some_python() Invoking py module: test.py 2008-01-22 21:46:12 [ERR] mod_python.c:106 eval_some_python() Error importing module 2008-01-22 21:46:12 [DEBUG] mod_python.c:180 eval_some_python() Threadstate mod_python.c swap-out! 2008-01-22 21:46:12 [NOTICE] switch_core_state_machine.c:201 switch_core_standard_on_execute() Hangup sofia/default/1001@192.168.0.12:5060 [CS_EXECUTE] [NORMAL_CLEARING] This suggests to me that the the dialplan is working correctly and we are trying to execute test.py, which from playing with file names I am fairly happy it is finding test.py , but beyond that I'm pretty well stuck for tonight. Any one got any thoughts as to where I might be going wrong. Many Thanks Steve

Re: [Freeswitch-users] dialplan and move temporarily

if you want to do that, Just use the "transfer" application. <action application="transfer" data="6000"/> you don't even need to bother with any sip then.

Yes you can use the "redirect" application to send a channel a protocol specific redirect response. In the case of a SIP channel it will be a 302 and the arg should be the full sup uri (including sip:) <action application="redirect" data="sip:user@domain.com"/> you can wrap this in <condition field="source" expression="mod_sofia" break="never"></condition> if you want to only send it on sip channels.
