CHAPTER 25 Routing SBC
Mediant 4000 SBC | User's Manual
Parameter Description
Note: If you need to route calls of many different destination URI
user names to the same destination, you can use tags (see 'Source
Tags' parameter below) instead of this parameter.
'Destination Host'
dst-host
[IP2IPRouting_
DestHost]
Defines the host part of the incoming SIP dialog’s destination URI
(usually the Request-URI).
The default is the asterisk (*) symbol (i.e., any destination host). If
this rule is not required, leave this field empty.
'Destination Tags'
dest-tags
[IP2IPRouting_
DestTags]
Assigns a prefix tag to denote destination URI user names
corresponding to the tag configured in the associated Dial Plan.
The valid value is a string of up to 70 characters. By default, no
value is defined. You can configure the parameter with up to five
tags, where each tag is separated by a semicolon (;). Each tag can
have a name and value (e.g., Country=Ireland) or only a value (e.g.,
Ireland). If you are configuring multiple tags in the name=value
format, the names of each tag must be unique (e.g.,
Country =Ireland; Land =Scotland). The tag is case insensitive.
To configure prefix tags, see Configuring Dial Plans .
Note:
■ Make sure that you assign the Dial Plan in which you have
configured the prefix tag, to the related IP Group or SRD.
■ Instead of using tags and configuring the parameter, you can use
the 'Destination Username Pattern' parameter to specify a
specific URI destination user or all destinations users.
'Message Condition'
message-
condition-name
[IP2IPRouting_
MessageConditionNa
me]
Assigns a SIP Message Condition rule to the IP-to-IP Routing rule.
To configure Message Condition rules, see Configuring Message
Condition Rules .
'Call Trigger'
trigger
[IP2IPRouting_Trigger]
Defines the reason (i.e., trigger) for re-routing (i.e., alternative
routing) the SIP request.
■ [0] Any = (Default) This routing rule is used for all scenarios (re-
routes and non-re-routes).
■ [1] 3xx = Re-routes the request if it was triggered as a result of a
SIP 3xx response.
■ [2] REFER = Re-routes the INVITE if it was triggered as a result
of a REFER request.
■ [3] 3xx or REFER = Applies to options [1] and [2].
■ [4] Initial only = This routing rule is used for regular requests
that the device forwards to the destination. This rule is not used
for re-routing of requests triggered by the receipt of REFER or
3xx.
