User's Manual

If the received header's original value is greater than the
parameter's value, the header's value is replaced by the user-
defined parameter's value.
The valid value range is 1-70. The default is 10.
Defines the SBC session refresh timer (in seconds) in the Session-
Expires header of outgoing INVITE messages.
The valid value range is 90 (according to RFC 4028) to 86400. The
default is 180.
Defines the minimum amount of time (in seconds) between session
refresh requests in a dialog before the session is considered timed
out. This value is conveyed in the SIP Min-SE header.
The valid range is 0 (default) to 1,000,000 (where 0 means that the
device does not limit Session-Expires).
Determines the device's privacy handling of the P-Asserted-Identity
header. This indicates how the outgoing SIP message asserts
identity.

[0] Don't Care = (Default) P-Asserted Identity header is not
affected.

[1] Add P-Asserted-Identity Header = Adds a P-Asserted-Identity
header. The header's values are taken from the source URL.

[2] Remove P-Asserted-Identity Header = Removes the P-
Asserted-Identity header.
Notes:

This parameter affects only the initial INVITE request.

The configuration of privacy handling in the IP Group table takes
precedence over the settings of this global parameter.

If in the IP Group this parameter is set to 'Don't care', then
the settings of this global parameter is used.

If this global parameter and the IP Group are set to 'Don't
care', the device uses the same P-Asserted-Identity header
(if present) in the incoming message for the outgoing
message.

This parameter can also be configured in an IP Profile.
Determines whether the device replaces the Contact user with a
unique Contact user in the outgoing message in response to a
REGISTER request.

[0] Disable = (Default) The device replaces the original Contact
user with a unique Contact user, for example:

Received Contact: <sip:123@domain.com>

Outgoing (unique) Contact: <sip:FEU1_7_1@SBC>

[1] Enable = The original Contact user is retained and used in the
outgoing REGISTER request.
Note: This parameter is applicable only to REGISTER messages
received from User-type IP Groups and that are sent to Server-type
IP Groups.
Determines the device's handling of REFER requests.

[0] Transparent = (Default) Refer-To header is unchanged and
the device forwards the REFER as is.

[1] DB URL = Changes the Refer-To header so that the re-routed
INVITE is sent through the SBC:
a. Before forwarding the REFER request, the device changes
