Corrected Text
--------------
   F3 ACK Alice -> Proxy 1

   ACK sip:bob@biloxi.example.com SIP/2.0
   Via: SIP/2.0/TCP client.atlanta.example.com:5060;branch=z9hG4bK12345
   Max-Forwards: 70
   From: Alice <sip:alice@atlanta.example.com>;tag=9fxced76sl
   To: Bob <sip:bob@biloxi.example.com>;tag=3flal12sf
   Call-ID: 3848276298220188511@atlanta.example.com
   CSeq: 1 ACK
   Content-Length: 0


Notes
-----
ACK is a new transaction and need a new value for via-branch
 --VERIFIER NOTES-- 
 The flow in the RFC is correct. ACK is only a new transaction if the final response to the INVITE was in the 2xx class. In this case, the final response was a 407 - this ACK is hop-by-hop, and is part of the INVITE transaction.
