asterisk users - Apr 2005 - weird call transfer problem

Guys.

I just had a weird problem. I have my Dial cmd configured with mwtWT as
parameters however, a call came in thru a zap channel and I answered on a
sip phone. I tried using # as configured on my features.conf file to
transfer the call but the "transfer" prompt never came in, so I asked
the
person on the zap channel to do the same and voila, he did get the transfer
prompt and entered and extension, but what happended is that I was the one
that got transfered! Not him! So..... Any ideas whats wrong?

The sip phone is an ata, a handytone 286 and zaptel cards.

Why cant I do the # transfer and they can but Im the one been transfered?

Hope you can help.

The "T" option allows the *calling* user to transfer the call, which
is what
happened to you. The "t" option allows the call recipient to transfer
the caller
to another extension. So to stop that from happening, remove the "T"
option from
the dial command.

As to why you yourself can't transfer it might have something to do with the
ATA
itself, check what dtmfmode is specified in sip.conf. From the sample sip.conf, 
it says:

dtmfmode=info			; either RFC2833 or INFO for the BudgeTone
