parameter's settings as a matching characteristic (input) to classify the
incoming INVITE to an IP Group (source IP Group) in the
Classification table. Once classified, the device uses the parameter for
routing the call. For example, if set to To, the URI in the To header of
the incoming INVITE is used as a matching characteristic for
classifying the call to an IP Group in the Classification table. Once
classified, the device uses the URI in the To header as the destination.

Note:

The parameter is applicable only when classification is done
according to the Classification table.

If the configured SIP header does not exist in the incoming INVITE
message, the classification of the message to a source IP Group
fails.

If the device receives an INVITE as a result of a REFER request or
a 3xx response, the incoming INVITE is routed according to the
Request-URI. The device identifies such INVITEs according to a
specific prefix in the Request-URI header, configured by the
SBCXferPrefix parameter. Therefore, in this scenario, the device
ignores the parameter setting.
Defines the IP Group as representing multiple registering servers,
each of which may use a single registration, yet represent multiple
users. In addition, it defines how the device saves registrations'
information for REGISTER messages received from the IP Group, in
its registration database. For requests routed to the IP Group's users,
the device replaces the Request-URI header with the incoming To
header (which contains the remote phone number).

[0] No = (Default) No extra key based on source IP address is
added to the registration database.

[1] Classify by IP = For initial registrations from the IP Group, the
device adds a key representing the user to its registration
database, based on the REGISTER request source IP address,
port (if UDP) and SIP Interface ID (e.g., "10.33.3.3:5010#1"). The
device classifies incoming non-REGISTER SIP dialog requests
(e.g., INVITEs) from the IP Group according to the received source
IP address. The device rejects initial registration requests that have
the same IP address, as the necessary key is already used for
another registration.
