He is using SIP phones.  Supervised Transfers do not really work with SIP.

He wants, on a SIP phone (I think he had Grandstream phones), to:
 o hit "transfer"
 o dial new extension
 o talk to new extension ***** this part does not work *****
 o hit "transfer" to complete the transfer or some cancel button to abort

Analog works just fine, with flash.
