Summary:                    On omitting the T flag from Dial() the caller can
still make a blind transfer
Description: 
I use allowtransfer=yes in sip.conf. I think if I omit the T flag from
Dial() in a dialplan extension, no blind transfer should be made by the
caller. But the caller can still make a blind transfer if he presses the
TRANSFER key.

A partial workaround is if I set allowtransfer=no in sip.conf, but this
will disable the blind transfer initiated by the caller side as well (which
is not what I would like to).
