[Freeswitch-dev] Problems with intercept application and attended transfer

[Francisco de Ezcurra]

I'm not trying to emulate the attended transfer. The problem is that if I use 
the intercept application I can no longer perform an attended transfer using 
the phone. The problem I mentioned in my previous email happens when I use 
the buttons of the Polycom phone to make the transfer.

These extensions are examples to show you the problem I'm experiencing.
In the real application I use mod_event_socket and originate to create the 
outgoing calls while the incoming call is waiting. Then I use intercept 
application to connect both channels. 

Thanks
Panchi

 First of all attended transfer is already supported within the SIP itself by
 the sip phone.
 The intercept app is not for attended transfer.
 If you insist on doing emulated attended transfer, there is an example in
 the default config using the bind_meta_app function.
