Nik, There's also a PHP library fs_sock.php under contrib in the source code. I used it to create a simple app that originates calls and then run some other sutff when it detects the call has ended. The actual call originate command is executed inside a javascript file which is run using bgapi jsrun. The js script also makes a POST request to an external URL using CURL. There's plenty to play around with, Freeswitch is really great, and mostly easy, a world of difference with *. Good luck!

Nik, There are a lot of ways to make FS dial out and deliver messaging etc. We are going through the process of replacing * for this purpose. For us (getting started with the help of our friends here on the list) it has been pretty easy. With * we were using AMI to originate calls ... to migrate to FS we just changed that to use event_socket with bgapi to originate the call and connect the call to a context and extension. There are several ways to get the dialplan to FS after that ... a script, xml_curl, or statically configured in the conf directory. So as an example the application we have just logs into the FS socket (similar to * but much better) and then rips off calls like this: bgapi originate{$set_some_vars}sofia/external/$ANI@$IP:$PORT $EXTENSION xml $CONTEXT The beauty of it all is that: -- a lot of flexibility in what you can do (like drive the call through events) -- the CDR reporting is about 3 million times better than * -- obviously higher capacity I'd start playing with event_socket and some static dialplans to get the feel for it ... but if you have an application written already to work with * (i.e. the logic and backend) it will be very easy to migrate and you'll be glad you did it!

Are you suggesting that I should process the call externally instead of using the dialplan? That would be neat as the audio file select could be driven from the db select for the number. I presume that I could also bridge the call to another number as well dependant on DTMF selection?

In addition do David's suggestion, you probably want to have your application to watch for some specific events after the call is originated and take action based on them. For example, you could watch for the CHANNEL_ANSWER event and play some audio file waiting for some digit, which is generated by the DTMF event. To watch only for those specific events, you should do the following just after authentication (still using Perl as an example, but the mod_event_socket is language agnostic), then you will receive those events from FreeSWITCH through the socket stream:
... print $sock "auth XXX\n\n"; print $sock "event plain CHANNEL_ANSWER DTMF\n\n"; ...
To see a list of available events, please look at the following wiki pages: http://wiki.freeswitch.org/wiki/Mod_event_socket#event http://wiki.freeswitch.org/wiki/Event_list

Raul

Hi Nik,
Here's a snipped in Perl that launches an outbound call:
if (my $sock = IO::Socket::INET->new(Proto =>'tcp', PeerAddr => '127.0.0.1', PeerPort => 8021)) { print $sock "auth XXX\n\n"; print $sock "api originate {softivr_id=$siid,src_softivr_id= $siid,softivr_outdial=true}sofia/frombt/$ntd@1.2.3.4 $service\n\n"; $sock->close(); }
- it does no error checking or anything, but (line by line) it: - opens a socket to the event socket interface - authenticates - issues an originate which dials out to the number in $ntd. The bits in {} set a bunch of variables on the channel, which are used by the software which processes the call later on. The call is linked to the extension in $service - FS looks this up in the dialplan - which handles our end. - closes the socket
Cheers --
Dave
Thanks for that, coming from a C++ background it's a refreshing change to be looking at something that seems logical and efficient.
I'd briefly looked at the event socket and wondered if that was the way to go. I presume that there's some sort of event generation that can trigger and external process as well somewhere, though all I need to do is update mysql (hopefully using some sort of pooled connection)
I'm not using a TDM card, I have a direct interconnect with the PSTN breakout provider with 1,500 channels available to me. I'm finding Asterisk proving to be less than stable at high call volumes and load values spike at more than 100 calls with billing/accounting in place, hence my interest in FS. The only thing that's concerning me is XML at the moment. Lots of code and very wordy. I'm sure I'll appreciate why XML given time
Regards,

Nik,
Welcome to FreeSWITCH! The short answer is "yes, FS can do that." The first thing that you should do is unlearn "the Asterisk way" of thinking. Usually there is an elegant way of doing things in FS that wasn't possible in Ast.
I would recommend that you start by looking at the event socket, which is somewhat analogous to the AMI only cooler. :) I have personally done something similar to this using the event socket and a Perl script. The key is to learn the syntax of the originate command. (definitely hit the wiki and IRC channel) Are you using TDM cards for this? Just curious.

Hi Guys,
As a long time Asterisk user, I'm looking into freeswitch as an alternative mainly due to (list multiple reasons here)
Can anyone give me a pointer as to how I would achieve the following?
I need to replicate an emergency broadcast system currently running under Asterisk.
At the moment, I run through a Mysql database and using the manager API, issues an Originate command to dial a number.
When the call is answered, a message is played, and the recipient has the option of hitting a digit to confirm receipt. I then call an AGI script to update the database.
Is this fairly easy to do in Freeswitch?
Not looking for code, just some pointers as to what's available to do the above /
