No.

A transaction is a request till the final response, e.g. INVITE-200 OK. 
or OPTIONS-200 Ok.

In SIP terminology a call is named "dialog". A dilaog consists of 
multiple transaction. The first transaction is the "dialog creating 
transaction" (e.g. INVITE) and the last transaction in this dialog is 
the "dialog terminating transcation" e.g. BYE.

Thus, INVITE and BYE are seperate transactions which belong to the same 
dialog.

Openser is transaction statefull, but not dialog statefull.
