Re: [Freeswitch-users] collectInput does not call callback function

29 May 2011

      I experience a similar problem after exiting a conference and continuing my 
C# App. Here is how it works. Caller is given options in
Session.StreamFile(play_info[i].filename, (int)start_off);

If he presses lets say '1'  Session.DtmfReceivedFunction is called by FS and 
caller gets put into a conference. I have conference maintenance events 
poped in a separate thread.

He presses '#' and gets back to the the same menu, but now if he presses '1' 
or '#'..anything during StreamFile , the Session.DtmfReceivedFunction is no 
longer called by FS. Once it goes into Get Digits after StreamFile a  press 
of the digit is returned ok.

I noticed, if I dont create EventConsumer for the conf maintenace, it works 
ok. I need it though to have more control over the conference. It smells 
like a bug.

If anyone knows where to look it is probable where a DtmfReceivedFunction 
callback during playback should occur if the caller is deleted from the 
conference instead of assuming that the dtmf will be reported by 
conference:maintenance event.

Hi folks!
I seem to have an odd problem, since it works for all others.  From my 
java
script I try to collect user input:
session.collectInput( mycb, "digits", 7000, 0);
where mycb is a regular function collecting user input:
function mycb( session, type, obj, arg )
{
  console_log( "info", "collect digits \n" );
  try {
      if ( type == "digits" )  {
        console_log( "info", "digit: "+obj.digit+"\n" );
        if ( obj.digit == "#" ) {
          console_log( "info", "detected pound sign.\n" );
          exit = true;
          return( false );
        }
dtmf.digits += obj.digit;
if ( dtmf.digits.length >= digitmaxlength ) {
          exit = true;
          return( false );
        }
      }
  } catch (e) {
      console_log( "err", e+"\n" );
  }
  return( true );
} //end function mycb
The very first line is a console info message, so I would know the 
function
is actually called. It never happens.  Right before collectInput call I 
have
a message playing a prompt, which I can hear.  So workflow definitely goes
into the collectInput function, and then after 7 seconds it continues with
dtmf.digits.length=0 even though I punched in the numbers, of course. 
Thats
another proof the callback function never was called.
Has anyone experienced this problem before? I run FS in Windows. 
Appreciate
your help.
Regards,
Sergei Kamen
