DESCRIPTION
"Session Initiation Protocol (SIP) Common MIB module. This
module defines objects that may be common to all SIP entities.
SIP is an application-layer signaling protocol for creating,
modifying and terminating multimedia sessions with one or more
participants. These sessions include Internet multimedia
conferences and Internet telephone calls. SIP is defined in
RFC 3261 (June 2002).
This MIB is defined for managing objects that are common to
SIP User Agents (UAs), Proxy, Redirect, and Registrar servers.
Objects specific to each of these entities MAY be managed using
entity specific MIBs defined in other modules.
Copyright (C) The IETF Trust (2007). This version of
this MIB module is part of RFC 4780; see the RFC itself for
full legal notices."

Example: If a user agent client supports, and requires the

(RFC 3262), this table contains a row with the option tag string
'100rel' in sipCommonOptionTag and the OCTET STRING value of
'1010 0000' or '0xA0' in sipCommonOptionTagHeaderField.
If a server does not support the required feature (indicated in
a Require header to a UAS, or in a Proxy-Require to a Proxy
Server), the server returns a 420 Bad Extension listing the
feature in an Unsupported header.
Normally, the list of such features supported by an entity is
static (i.e., will not change over time)."

MAX-ACCESS read-only
STATUS current
DESCRIPTION
"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."
