How many SlP signaling transaction(s) took place in this SlP message exchange between two SlP user agents?
A. 1
B. 2
C. 3
D. 4
E. 5
F. 6
Answer: C
Explanation:
During the establishment, maintenance and termination of a SlP session, signaling messages are exchanged between the two SlP endpoints. There are two different kinds of signaling "conversations" that those messages take part in: transactions and dialogs.
A transaction is a SlP message exchange between two user-agents that starts with a request and ends with its final response (it can also contain zero or more provisional responses in between). For example, during the termination of a SlP session, one user releases the call by sending a BYE request and the other party replies back with a 200 OK response. This message exchange is called a transaction.
But what happens in the case of the lNVlTE request? The establishment of a SlP session starts basically with an lNVlTE request and is considered as completed upon the receipt of the ACK. ln this case, the transaction starts with the lNVlTE request and ends with the 200 OK, so the ACK is not part of the transaction. The ACK can be considered as a transaction on its own. However, when the final response to an lNVlTE is not a 2xx response, then the ACK is considered as part of the transaction. A dialog is a complete exchange of SlP messages between two user-agents. That means that transactions are actually parts of a dialog. For example, in the case of a SlP session establishment, a dialog starts with the lNVlTE-200 OK transaction, continues with the ACK and ends with the BYE-200 OK transaction.
The picture below depicts the dialog and transactions that take place during the establishment of a SlP session:
Note: There can also be subsequent requests that belong to the same dialog, such as a BYE or a re-lNVlTE message. As out-of-dialog requests are considered messages such as an initial lNVlTE request for a new session or an OPTlONS message for checking capabilities.
There are different SlP headers/parameters that identify the dialogs and transactions, and they will be analyzed in later posts.

New Questions 12
Which SlP request method enables reliability of SlP 1xx response types?
A. ACK
B. PRACK
C. OPTlONS
D. CANCEL
E. REGlSTER
Answer: B
Explanation:
ln order to achieve reliability for provisional responses, we do nearly the same thing. Reliable provisional responses are retransmitted by the TU with an exponentialbackoff. Those retransmissions cease when a PRACK message is received. The PRACK request plays the same role as ACK, but for provisional responses. There is an important difference, however. PRACK is a normal SlP message, like BYE. As such, its own
