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

2009-02-03 Thread Nik Middleton

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.

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

2009-02-03 Thread David Knell


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

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

2009-02-03 Thread Raul Fragoso

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;
...

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?

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

2009-02-03 Thread Shelby Ramsey

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!

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.


 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?

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!

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.

 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:

  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

   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
