Hi ALL
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
