The trick is not to use options you don't understand.  "show application
dial" will show you what the t and T options are for. 
Most people use the transfer feature of their phone, rather than using
the T/t hack on the Dial line.

Sounds like you are using CVS-HEAD and so will have to configure stuff
in /etc/asterisk/features.conf.

Eric,

Thanks for the pointers. Here is my Features.conf where I have tried my
best to use Asterisk to give away control. I have enabled ## as the
combination key for Asterisk (in quick succession) to retain control,
but otherwise ignore the key presses.

What is your sggestion for the dial command? Removing the ',Tt' did not
hel either.
Shall I add back 'Answer' as the first pripority before the 'Dial'?
