CHAPTER 25 Routing SBC
Mediant 4000 SBC | User's Manual
Parameter Description
■ The IP Group must be associated with the assigned SRD
(see the 'SRD' parameter in the table).
'IP Group Tag Name'
ip-group-tag-name
[Classification_
IpGroupTagName]
Defines the source tag of the incoming SIP dialog. The tag is
used for classifying the SIP dialog to an IP Group. The tag is
obtained from the Call Setup Rule that is associated with the SIP
Interface on which the dialog is received.
The valid value is a string of up to 70 characters. The default
value is "default", which must be used when the resultant tag
from the Call Setup Rule is only a value (e.g., "Ireland"). If the
resultant tag is a name=value (e.g., "Country=Ireland"), then
configure the parameter with the
name only (e.g., "Country").
Only one tag name can be configured.
For more information on Classification of incoming SIP dialogs to
IP Groups using tags, see
Configuring Classification Based on
Tags on page 544.
Note: The parameter is applicable only if you configure the 'IP
Group Selection' parameter to Tagged IP Group .
'IP Profile'
ip-profile-id
[Classification_
IpProfileName]
Assigns an IP Profile to the matched incoming SIP dialog.
The assigned IP Profile overrides the IP Profile assigned to the IP
Group (in the IP Groups table) to which the SIP dialog is
classified. Therefore, assigning an IP Profile during classification
allows you to assign different IP Profiles to specific users (calls)
that belong to the same IP Group (User or Server type).
For example, you can configure two Classification rules to
classify incoming calls to the same IP Group. However, one
Classification rule is a regular rule that doesn't specify any IP
Profile (IP Profile assigned to IP Group is used), while the second
rule is configured with an additional matching characteristic for
the source hostname prefix (e.g., "abcd.com") and with an
additional action that assigns a different IP Profile.
By default, no value is defined.
Note: For User-type IP Groups, if a user is already registered with
the device (from a previous, initial classification process), the
device classifies subsequent INVITE requests from the user
according to the device's users database instead of the
Classification table. In such a scenario, the same IP Profile that
was previously assigned to the user by the Classification table is
also used (in other words, the device's users database stores the
associated IP Profile).
Classification Based on URI of Selected Header Example
The following example describes how to configure classification of incoming calls to IP Groups,
based on source URI in a specific SIP header. The example assumes the following incoming
INVITE message:
INVITE sip:8000@10.33.4.226 SIP/2.0
