Question : Call Transfer not working

Can someone help me understand the following configuration- unable to transfer calls..

transfer-system full consult
transfer-pattern .T
transfer-pattern 1..
secondary-dialtone 0
.
.
ephone-dn 1  dual-line
 number 80
 pickup-group 10
 label ABC 80
 description ABC
 name ABC
 call-forward busy 99
 call-forward busy noan 99 timeout 15

There's dual channel for each ephone.
I have a feeling that the "transfer-pattern 1.. " is the culprit. Anyone can explain it for me?

try to debug the dial-peer to check if you are hitting one of them by using debug voice dial-peer in.
