sipCommonSummaryTotalTransactions

This object contains a count of the number of transactions that
are in progress and transactions that have reached the
'Terminated' state.  It is not applicable to stateless SIP Proxy
Servers.
              
A SIP transaction occurs between a client and a server, and
comprises all messages from the first request sent from the
client to the server, up to a final (non-1xx) response sent
from the server to the client.
              
If the request is INVITE and the final response is a non-2xx,
the transaction also include an ACK to the response.  The ACK
for a 2xx response to an INVITE request is a separate
transaction.
              
The branch ID parameter in the Via header field values serves
as a transaction identifier.
              
A transaction is identified by the CSeq sequence number within
a single call leg.  The ACK request has the same CSeq number as
the corresponding INVITE request, but comprises a transaction
of its own.
              
In the case of a forked request, each branch counts as a single
transaction.
              
For a transaction stateless Proxy Server, this counter is
always 0.
              
Discontinuities in the value of this counter can occur at
re-initialization of the SIP entity or service.  A Management
Station can detect discontinuities in this counter by
monitoring the sipCommonSummaryDisconTime object in the same
row.
