Using outbound Event Sockets versus using embed language scripts
by Herman Griffin 24 Feb '11

24 Feb '11

Unless I'm complicating things, it seems like a drop to write outbound event sockets apps versus writing embedded language apps. However, I'm interested in writing event sockets apps because I can see an advantage in being able to load balance the app by running you app behind a load balancer. One simple thing that I am trying to accomplish is collecting digits and doing something useful with string of digits that have been collected. My first attempt at this is to use the play_and_get_digits dptool, but I don't now how to pull data from stored variable so that I can use in the script. I slightly modified the freeswitch.git/libs/esl/perl/server2.plscript by adding this line: $con->execute('play_and_get_digits', '2 5 3 7000 # ${base_dir}/sounds/en/us/callie/conference/8000/conf-pin.wav /invalid.wav foobar \d+' ); The next thing that I'd like to do is grab the value in foobar is use it in the perl logic. Can someone lead me to the next step? Does anyone with experience with event socket apps and embedded language apps have some useful information about their preferred path? Thanks, Herman

play media
by Jason b.a 24 Feb '11

24 Feb '11

coz i need freeswitch only for media processing, i dont want to have a direct SIP connection between user and Freeswitch, so the application server can handle the call using SIP, and using the event socket, it can ask freeswitch to play prompt, or collect digit and return it to the application so the application according to the digits can bridge the call. is it possible ? and how freeswitch can play RTP to the caller ?

guys in this case: sip caller -------Sip-------- Application server -------socket------- FreeSWITCH in this case how freeswitch is going to play media (RTP) for the sip caller, if i am only using the socket interface of freeswitch. Thx in advance !

I'd like to execute an app while from CLI on an answered channel (I know the uuid) and pass vars on it like {exec?} <app with vars and params> <uuid> or if it's not possible execute an extension from CLI with a uuid Thanks

Hi, I tried FreeSWITCH Version 1.0.head (git-f5dafc9 2011-01-21 23-42-30 +0100) FreeSWITCH Version 1.0.head (git-06988e1 2011-02-20 15-10-02 -0600) originate user/1000 &echo got this: INVITE sip:tbskvnyi@192.168.7.2:61901 SIP/2.0 Via: SIP/2.0/UDP 192.168.7.2;rport;branch=z9hG4bK0USe34K3r46gF Max-Forwards: 70 From: "" <sip:0000000000@192.168.7.2>;tag=cZt7ZSBZjQK3H Remote-Party-ID: <sip:0000000000@192.168.7.2>;party=calling;screen=yes;privacy=off And some versions of Xlite4 fails to respond to this originate {origination_caller_id_name=xxx}user/1000 works. I haven't got time to test git head (02-20 almost head), just want to ask here anyone noticed this, let me know if need a jira. btw, vars.xml is untouched: <X-PRE-PROCESS cmd="set" data="outbound_caller_name=FreeSWITCH"/> <X-PRE-PROCESS cmd="set" data="outbound_caller_id=0000000000"/> Thanks. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

SIP SUBSCRIBE for as-feature-event events
by Helmut Kuper 23 Feb '11

23 Feb '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, Snom is supporting subscriptions to as-feature-event Events. Unfortunately FS replys with "Bad Event" to this. Are there plans to support such subscriptions? Maybe the headers and body can be passed to an application? Or the whole thing could be forwared to an application server to work on it. The SIP message looks like this: Session Initiation Protocol Request-Line: SUBSCRIBE sip:2850@a.a.a.a SIP/2.0 Message Header Via: SIP/2.0/UDP b.b.b.b:5060;branch=z9hG4bK-b3v8fu4shagb;rport From: <sip:2850@a.a.a.a>;tag=dq168o7qj9 To: "Helmut Kuper" <sip:2850@a.a.a.a> Call-ID: 3c26705696f0-6ntjya2y7b3s CSeq: 2 SUBSCRIBE Max-Forwards: 70 Contact: <sip:2850@b.b.b.b:5060>;reg-id=1 Event: as-feature-event User-Agent: snom370/8.4.27 Expires: 3600 Content-Type: application/x-as-feature-event+xml Content-Length: 185 Message Body <?xml version="1.0" encoding="ISO-8859-1"?><SetDoNotDisturb xmlns="http://www.ecma-international.org/standards/ecma-323/csta/ed3"><doNotDisturbOn>true</doNotDisturbOn></SetDoNotDisturb> Best regards Helmut -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1dI6wACgkQ4tZeNddg3dx0LQCdGPIHZWb5tUEaP4SOMl7cWJrE f38AoK1NEd9VeOUJ6Ut+XAyZgS6LdcZz =JLAn -----END PGP SIGNATURE-----

INVITE DoS Prevention
by Spencer Thomason 23 Feb '11

23 Feb '11

Hi, We run hosted Freeswitch instances in VMs with the internal profile on port 5060 connecting to clients mostly behind NAT and then the external profile connecting to our proxies only. Protecting the external profile its straightforward.. we only allow traffic to/from our proxies at the firewall level. But protecting the internal profile seems to be a bit more difficult because the UACs could be theoretically anywhere on the network. I'm currently using Fail2Ban to prevent brute force registration and INVITEs on auth failures, e.g.: failregex = \[WARNING\] sofia_reg.c:\d+ SIP auth failure $REGISTER$ on sofia profile \'\w+\' for \[.*\] from ip <HOST> \[WARNING\] sofia_reg.c:\d+ SIP auth failure $INVITE$ on sofia profile \'\w+\' for \[.*\] from ip <HOST> My question is, since its part of a normal SIP dialog to challenge the INVITE, is there any way to prevent a possible DoS from just sheer volume of incoming INVITEs on an Internet facing server automatically. I.e., If you block the logged challenge, you'd block all legitimate INVITEs and registrations. Since its UDP traffic I couldn't come up with a way to do it automatically at the iptables level. i.e. number of concurrent connections. Is there some option to just not respond if a client is sending a number of requests over a certain threshold? It might not stop them from sending the traffic but pretty soon they'd get the idea that it wasn't going to go anywhere. My concern is say there are 50 Freeswitch instances on a box (albeit 8 core, 32GB ram, 8 15K raid 10 storage) and someone starts sending thousands of rouge INVITEs to every VM on a physical box that the CPU load from just challenging the incoming INVITEs would create a DoS. We the logs regularly to try to catch people doing this sort of thing and drop them at a router upstream of the core network, but I'd like to have it happen without human intervention. Have I completely over thought this and am missing something obvious? Thanks, Spencer
