Summary:                    SIP attended transfer cannot re-transfer a caller
after a call forward no answer rule returns call to original extension
Description: 
Here is setup:
6011 will call 6002
6002 will transfer to 6010
6010 has forward no answer rule to 6002
6002 must answer and try to transfer caller to another extension using SIP
attended transfer (Polycom phone firmware 3.1.1

Result:
after timeout to 6010 caller is sent to vm6002 instead of transferred back
to 6002 (core show channels does not show 6002 on call after transfer
completion.

Note:
The only workaround for this is to use SIP blind transfer.
Native *1 Asterisk transfer will follow the call forward no answer rule on
6010 to transfer to 6002, but once the caller is returned to 6002 then 6002
cannot use the blind transfer feature again
