Branch Parameter Settings
The following are settings related to the Branch parameter.
Branch Matching Method
You can configure the method used to match incoming SIP packets with a branch. A branch could be
described as a link that allows to match a response to a request.
X
To configure the branch matching method:
1.
In the
sipInteropMIB
, set the
sipInteropBranchMatchingMethod
variable with the proper method to
use.
Transaction Matching Procedure
You can configure the use of the
Via
branch behaviour for incoming CANCEL requests. You can specify
whether the SIP stack’s transaction matching procedure ignores the branch parameter of the
Via
header field
in CANCEL requests with no
To
tag.
X
To configure the use of the Via branch behaviour for CANCEL requests:
1.
In the
sipInteropMIB
, set the
sipInteropIgnoreViaBranchIdInCancelEnable
variable with the proper
behaviour.
Standards Supported
•
RFC 2543 – SIP: Session Initiation Protocol, section 10.1.2
•
RFC 3261 – SIP: Session Initiation Protocol, section 8.1.1.7
Table 147:
Branch Matching Method
Method
Description
rfc2543
Follows the method described in RFC 2543 (section 10.1.2). Responses are
mapped to requests by the matching
To
,
From
,
Call-ID
, and
CSeq
headers and
the branch parameter of the first
Via
header.
rfc3261
Follows the method described in RFC 3261 (section 8.1.1.7). A
Via
is inserted
into the request and the
Via
header field value must contain a branch parameter.
This parameter is used to identify the transaction created by that request. It is
used by both the client and the server.
The branch ID is used to facilitate its use as a transaction ID. It must always begin
with the characters “z9hG4bK”. If this is not the case, the Mediatrix 1204 uses the
branching method as described in RFC 3261, section 17.2.3.
Table 148:
Via Branch Behaviour
Method
Description
disable
The transaction matching procedure behaves according to section 17.2.3 of RFC
3261. This is the default value.
enable
The branch parameter is not used as a transaction matching criterion for
CANCEL requests with no
To
tag.
