Note:

If you have assigned a Routing Policy to a Classification rule that is
associated with the SRD, the Routing Policy assigned to the SRD
is ignored.

You can assign the same Routing Policy to multiple SRDs.
Enables the SRD to be used by a third-party routing server for call
routing decisions.

[1] Used
For more information on the third-party routing server feature, see
''Centralized Third-Party Routing Server'' on page 278.
Assigns a Dial Plan to the SRD. The device searches the Dial Plan for
a dial plan rule that matches the source number and if not found, for a
rule that matches the destination number. If a matching dial plan rule
is found, the rule's tag is used in the routing and/or manipulation
processes as source and/or destination tags.
To configure Dial Plans, see Configuring Dial Plans on page 541.
Defines the maximum number of users belonging to the SRD that can
register with the device.
The default is -1, which means that the number of allowed user
registrations is unlimited.
Defines the blocking (reject) policy for incoming SIP dialog-initiating
requests (e.g., INVITE messages) from registered and unregistered
users belonging to the SRD.

[0] Accept All = (Default) Accepts requests from registered and
unregistered users.

[1] Accept Registered Users = Accepts requests only from users
registered with the device. Requests from users not registered are
rejected.

[2] Accept Registered Users from Same Source = Accepts requests
only from registered users whose source address is the same as
that registered with the device (during the REGISTER message
process). All other requests are rejected. If the transport protocol is
UDP, the device verifies the IP address and port; otherwise, it
verifies only the IP address. The verification is performed before
any of the device's call handling processes (i.e., Classification,
Manipulation and Routing).
Note:

The parameter is applicable only to calls belonging to User-type IP
Groups.

The feature is not applicable to REGISTER requests.

The option, Accept Registered Users from Same Source [2] does
not apply to registration refreshes. These requests are accepted
even if the source address is different to that registered with the
device.

When the device rejects a call, it sends a SIP 500 "Server Internal
Error" response to the user. In addition, it reports the rejection
