Summary:                    calls not routing to polycom handset after transfer
using softkeys
Description: 
We are running asterisk 1.6 and AGI scripts for call flow. Because Polycom
handset handles most of transfer when using soft keys, the AGI script is
never notified of the handset hanging up after transfer is complete.
Therefore AGI script believes handset is busy (487 Busy Here is sent) until
the transferred call is terminated

---------------------------------------------------------------------- 
Problem is Asterisk informs the AGI script of a new outbound call over the
AGI connection, it doesn't tell the AGI script whether this call is going
to be a transfer (and which call it's going to be a transfer for) or a
plain outbound call. This is because both:

1. Asterisk probably doesn't know that this is going to be a transfer, as
it has not yet received the REFER packet from the handset.

2. Asterisk's AGI mechanism was never designed with complex call flows in
mind.
