[Freeswitch-users] random DTMF after bridge attempt timeout in Javascript

[Andy Ayers]

Hi,

 

I have the following script snippet (simplified for the purposes of this
request):

 

if (session.ready()) {

       // Play a welcome message, "please wait while we try to connect your
call"

       session.sayPhrase('play', 'welcome.wav');

       session.execute("set",
"ringback=%(400,200,400,450);%(400,2000,400,450)");       

session.execute("bridge",
"{effective_caller_id_number=XXXX,origination_caller_id_number=XXXX,ignore_e
arly_media=true,continue_on_fail=true,hangup_after_bridge=false,originate_ti
meout=20}sofia/outbound/YYYY at sip.node4.co.uk");

       if (session.getVariable("bridge_hangup_cause") != 'NORMAL_CLEARING')
{

             // Play a sorry we could not connect your call message

             session.sayPhrase('play', 'sorry.wav');

// Ask if they would like a callback, "press 1 if you would like a callback"

             session.sayPhrase('play', 'callback.wav');

session.flushDigits();

var callback = session.getDigits(1, '', 5000);

if (callback=='1') {

       //Do some more stuff

}            

       }

}

 

The problem I have is that if the bridge attempt times out, after playing
the callback.wav request message and whilst waiting for input the session
receives a random dtmf digit '6' without the caller pressing any keys on the
keypad.

 

Can anyone tell me where this digit comes from and how to prevent it from
coming in on the original session? Or else tell me that I've got it all
completely wrong and tell me how I can achieve the required call handling in
a different way?

 

Many thanks

Andy
