Summary:                    When transferring a call using the REFER command
with replaces enabled, Asterisk drops the call.
Description: 
When transferring a call using the REFER command with replaces enabled,
Asterisk drops the call with "SIP/2.0 481 Call leg/transaction does not
exist". I have tried performing this on 1.4 SVN, 1.8.3, Trunk SVN 309404,
and 1.8 SVN 309808. All have produced the same result. I have attached the
debug logs with core and sip debugging on. Unfortunately I do not have a
way to perform a successful transfer with REFER to compare against. Line
432 is where the REFER starts. Chan_sip.c starts to process the REFER but
then later drops it on line 538 with the "SIP/2.0 481 Call leg/transaction
does not exist".
