This may not be generalized clarification .I am conidering set up i work with 
which has two end point seperated by a stateful proxy .
Please refer page 122 RFC 3261"17Transactions "
So considering the RFC note and considering a proxy in between 
There are total 7 transactions in this call flow.

Invite<-> 200ok1 
ACK 1    ------(3261 which  says that ACK for 2xx to INVITE request is a different transaction)
Hold  2           |  
                          ----- 7 Transactions     
Unhold 2        | 
Bye 1      ------     
And if there is proxy in between but a stateful one so Proxy will create the new transaction for incoming Invite  request
Re-Invite will create the new transaction .
so that allows me to conclude 7*2 theory if we see the the complete dialog
