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.
