Thanks Anthony, I will update to latest. I last did a pull about 2 weeks ago, FreeSWITCH Version 1.0.head (git-8c5586b 2011-04-01 14-22-43 -0500). If I shouldn't be doing this in this script, then what is the recommended way to originate an outbound IVR call? My current production application uses Microsoft Speech Server to send outbound customer service calls, with a B2BUA I wrote to communicate with terminators. I'm switching my B2BUA out for FreeSwitch, and it's working great. But if possible I'd like to remove MSS from the equation altogether. Lua looks like a good way to control the call workflow.

I've been fiddling around with things this morning and I am using a combination of PHP and Lua. I use php to simply originate the call (using regular sockets to talk to 8021, not the php mod for ESL, since I can't get it to compile). In the originate command I specify a Lua script that handles the rest of the call. I'm using the PHP functions described here: http://wiki.freeswitch.org/wiki/PHP_Event_Socket My PHP: $fp = event_socket_create("127.0.0.1", 8021, "ClueCon"); $channelVars = "{ignore_early_media=true,origination_caller_id_number=18778502010}"; $phoneNum = "17277762768"; $notificationId = "x"; $cmd = "bgapi originate $channelVars". "sofia/gateway/affinity/".$phoneNum." &lua('test2.lua $notificationId')"; echo "Sending command: $cmd"; $response = event_socket_request($fp, $cmd); echo $response; fclose($fp); My Lua: prompt = "/home/eric/test1.wav" session:streamFile(prompt) session:hangup() This is working for the very basic scenario of just waiting for the number to pick up, playing a wav, and then hanging up. If anybody can point out any major showstoppers that would prevent me from handling significant user interaction, I'd love to hear about them now.

I didn't say you can't use LUA The only point I was trying to make is: if you are running the lua script on an inbound call, then you just create a new session and ignore the one the call came in on you have an issue. lua is best when you are trying to make an IVR or do advanced logic that is too much for the XML dialplan. You have a single channel and you use the channel data to do things on that channel. One big mistake people tend to make is they think that embedded scripting is a shortcut to making complex apps without thinking through the requirements. Also doing things like trying to setup and bridge 2 channels together in lua manually is unwise. The originate syntax is the same everywhere including with the bridge app. The best thing to do is use your script to figure out the params you need for the originate syntax of the B leg then simply set that as a variable, exit the script and pass that variable to the bridge app from your dialplan. If you need to be fully asynchronous you for sure want to consider ESL. On Wed, Apr 13, 2011 at 10:01 AM, Michael Collins <msc@freeswitch.org> wrote:

You can run pretty much any dialplan application from Lua using the session:execute method. I don't see any issues with you originating the calls via event socket and then handling the answered calls with a Lua dp script. -MC _______________________________________________ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
