Re: [Freeswitch-dev] bridging calls using mod_managed

9 Jan 2012

      Hi,

I did managed to get something to work. I placed complete code on pastebin:
http://pastebin.com/eCsYSdfk I don't know why exactly it works now, I think
it has something to do with a public decalration of my leg_a as managed
session and using that, now I pass the contect.Session every time and
create that as a local leg_a reference and that seems to work...

Still I have some problems with I need realy need somebody to help me
with...

1. immediately after the bridge (log says exact same timestamp) the HangUp
handler is invoked. (it seems as a separate part, as the rest of my code is
handled too) Why is the hangup handler called when the bridge is started
and how to avoid this?

2. After the bridge I need to get into a loop to continue my code while in
the bridge, and after the bridge, depending on who hung up. So after bridge
I go into while loop like:
     while(leg_a.bridged() && leg_b.bridged()) { }
But the both return false immediately. Al other functions (
contect.Session.Ready() ) return false too, though my code continues and
just continues my function. How can I make this work?

My (custom debug)log shows:

Subject: [Freeswitch-dev] bridging calls using mod_managed
Hi,
I've been working with FS for some time now, and are progressing. I am
working on a platform (in/ivr) which is handled by .net managed code
completely. I am using just 1 application which is always launched on
incomming calls.
This application immedeately connects with my MSSQL server and checks
validity of gateways, inbound number etc. Also a cdr is written and updated
periodically while the call is active.
I have als set the HandleHangUp handler to finalize the cdr and call
when the calller disconnects.
This whole mechanism works as a charm. This application then plays
voicefiles, getdigits, and everything as I would expect.
Hoewever at some point I want to dialout to an external number and
connect these two calls together.
I do not want to leave the originating .net app as long as my incomming
caller is still online (to update the cdr and finalize the call).  While
these two are connected I need to update my database periodicaly
(keepalive).
I have been looking the internet to find what I need but i can't get it
to work 100%. In fact everything works, but when I bridge the two calls
together it fails.
I use the following and this whole peace of code actually works, it
dials out, aborts when someone hangsup and when the b_leg picks up they
both get audiofile turn by turn.... It even checks outbuond status and maps
this to the original call. (so really acts like a switch).
Debug("Got a route=>"+route+", Let the network play
the ringtone...");
                   leg_a.Execute("ring_ready", "");
Debug("Creating the new session...");
                   ManagedSession leg_b = new
ManagedSession("sofia/external/"+route);  // route holds
{destinationNumber}@{myExternalGateway<mailto:%7bdestinationNumber%7d@
%7bmyExternalGateway>}
                   if (leg_b.Ready())
                   {
                       Debug("Session_B ready!");
                       string fsuuid_b = leg_b.GetVariable("uuid");
Debug("Waiting for B-Leg to answer and A-Leg not
to hangup...");
                       while (!leg_b.answered() && leg_a.Ready() ) { /*
Ringing... */ }
if (leg_b.answered())
                       {
                           Debug("...B-Leg is answered");
                           AnswerCall(leg_a);
                           while (!leg_a.answered()) { }
                           Debug("...A-Leg is answered");
// ****** BRIDGE SHOULD BE HERE ******
Debug("As long as both legs are Ready(), we
wait......");
                           while (leg_b.Ready() && leg_a.Ready())
                           {
                               Play(leg_b,
"Test\\dir-no_matching_results.wav"); // REMOVE WHEN BRIDGED
                               Play(leg_a,
"Test\\dir-no_matching_results.wav"); // REMOVE WHEN BRIDGED
                           }
Debug("There is one leg no longer ready...");
                           if (leg_a.Ready()) { Debug("Session A still
ready..."); } else { Debug("Session A NO LONGER ready...");}
                           if (leg_b.Ready()) { Debug("Session B still
ready..."); } else { Debug("Session B NO LONGER ready...");}
                       }
                       else
                       {
                           Debug("A-Leg aborted while dialing...");
                       }
if (leg_b.Ready())
                       {
                           Debug("B-Leg still here, so hanging up
B-Leg...");
                           leg_b.Hangup("NORMAL_CALL_CLEARING");
                           leg_b.destroy();
                       }
                   }
                   else
                   {
                       string obCause = leg_b.hangupCause();
leg_a.HangUp(obCause);
                       Debug("Route failed with: "+obCause);
                   }
                   return true;
Of course I need to bridge the two calls together so they can speak to
each other.. I am trying to bridge the call at "// ****** BRIDGE SHOULD BE
HERE ****** " like this:
leg_a.sleep(1000, 0);
string apiResult = fsApi.ExecuteString(string.Format("uuid_bridge {1}
{0}", leg_a.GetUuid(), leg_b.GetUuid()));
Debug("apiResult="+apiResult);
The console log shows "+OK {guid of leg_a}
but at the very same moment the incomming calls is beging hung up, (I
can see the Debug message of my HandleHangUp() at exactly the as me time as
the apiResult of the bridge.
I have checked without bridge to check if codecs are the the same and
they both are PCMU 8000.
Please any help is appreciated! I have been trying to make this work for
over a week now, but it won''t work.
note. I have also tried originate with the api, but gives me the same
problem when I try to bridge these two legs together...
Best Regards,
Mike.
