Re: [Freeswitch-users] Generating calls from external source
Hi Nik,
That's one possibility, yes. You could use mod_xml_curl to provide the
dial-plan on the fly and then use mod_event_socket to send commands to
FS and process events. That's exactly what I do actually, we have an IVR
engine that is driven by mod_event_socket and another module that
provides the XML dial-plan through mod_xml_curl.
The beauty of FS is that you have many options to tack a problem, and
all of those options are very elegant. I suggest looking at
mod_event_socket first and then decide if you can live with the static
dial-plan or go to a more dynamic dial-plan via mod_xml_curl.

Raul

Re: [Freeswitch-users] Generating calls from external source
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!

I'm not saying you should, merely that you could. What I did was
create a bunch of extensions in my dialplan that handled various steps
of the IVR outbound call: start, answered, busy, not answered, SIT
tones, etc. So my originate command would originate the call (A leg)
and drop the B leg into the dialplan at the "start" extension and then
it goes from there. It listens for early media busy or SIT tones and
also does an "execute_on_answer" to the extension that does the actual
IVR. (Only need the IVR on an answered call.) If the call is not
answered after 25 seconds then I run a Lua script that checks for the
presence of certain channel variables that I set with the
"tone_detect" application (busy and SIT). If none of those are present
then I assume the call went unanswered and do the post-processing.

Yes, you can do this as well. You can build an IVR in XML or you can
build in a scripting language like Lua:
demo IVR:
http://svn.freeswitch.org/svn/freeswitch/trunk/conf/autoload_configs/ivr.conf.xml
Lua IVR info: http://wiki.freeswitch.org/wiki/IVR#Lua_IVRs
Sorry if this is all a bit overwhelming, but you'll be glad that you
dove in to FS because it does s much and does it so well. Enjoy!

Re: [Freeswitch-users] Generating calls from external source
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{$set_some_vars}sofia/external/$...@$ip:$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!

Re: [Freeswitch-users] Generating calls from external source
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";

As a matter of fact that is the module I used for my outbound IVR
application. It simply handled the communications between my perl
script and my FS instance. The script would read in pre-formatted
originate strings from a text file that had been previously generated
by another application. Then all I had to do was specify how many
concurrent channels that I wanted - kind of like a throttle - and then
I let the script go. I used the "bgapi originate" syntax so that I
wouldn't have to wait to see what happened with each origination
attempt. Then about every second or so I would issue an "oz dump 1"
and parse the results to count how many b channels were in use. If the
number of b channels in use was >= my throttle limit then I'd pause
the script for 1000ms and then issue the oz dump again until the
number of b channels in use had dropped down below my limit. Nothing
too fancy.
You're welcome to review my script, originate syntax, and dialplan
entries if you are interested.

Re: [Freeswitch-users] Generating calls from external source
There is also an event socket library written in C called esl that is in the
fs tree in the libs directory.
This has the ability to establish connections both inbound and outbound from
FS.
There is also a perl module FreeSWITCH::Client that mr collins may be
interested in in the tree as well.

Re: [Freeswitch-users] Generating calls from external source
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:

Re: [Freeswitch-users] Generating calls from external source
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=$siid,softivr_outdial=true}sofia/frombt/$...@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

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

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.

I need to replicate an emergency broadcast system currently running

At the moment, I run through a Mysql database and using the manager

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?
