Summary:                    [patch] SIP Attended Transfer fails
Description: 
Hi!
The attended trasfer fails in the following scenario:
PBX: Aterisk 1.4.23
Extensions: 1, 2 and 3

Extension 2 call extension 1. 
Extension 1 puts extension 2 on hold.
Extension 1 calls extension 3.
Extension 1 put extensions 3 on hold.
Extension 1 refers extension 3 to extension 2  

--> Asterisk sends NOTIFY with message/sipfrag:
  SIP/2.0 481 Call leg/transaction does not exist

and the transfer fails.

The failure happens only if the REFER is sent to extension 3. If
extensions 1 refers extension 2 to extension 3, then everything works
fine.

I have tested with recent SNOM and eyebeam clients - same result, transfer
does not work.
