Summary:                    Problems when doing an attended and unattended
transfer with Thomson Phones
Description: 
When doing an attended transfer (party A -> B -> C) the phones A & B start
ringing after they finished the active call, but there is no audio
(ghostcalls)

When doing an unattended transfer the phone B (transferrer) start ringing
immediatly after transfering the party A to C.

I loaded 1.4.13 last night. Using Polycom 600 phones, I can initiate an
attended transfer to a third phone (A->B->C) A goes on Hold and B<->C are
sending two way RTP. When I press the Transfer button again to connect
A<->C, the call disconnects. It appears that the attended transfer fails
right after a 491 between network and Asterisk server. Asterisk sends a BYE
to disconnect the call.

Blind transfer works. The difference appears to be a matter of timing
between SIP INVITES. Will report more tomorrow. 

Conferencing work fine as well.

file - Should this problem continue under this issue or should another bug
report be created.
