User's Manual
Enables the device to always send SIP requests and responses,
within a SIP dialog, to the source IP address received in the
previous SIP message packet. This feature is especially useful in
scenarios where the IP Group endpoints are located behind a NAT
firewall (and the device is unable to identify this using its regular
NAT mechanism).

[0] No = (Default) The device sends SIP requests according to
the settings of the global parameter, SIPNatDetection.

[1] Yes = The device sends SIP requests and responses to the
source IP address received in the previous SIP message
packet.
For information on NAT traversal, see Remote UA behind NAT on
page 152.
Defines a value for the SIP user part that can be used in Message
Manipulation rules configured in the Message Manipulations table.
The Message Manipulation rule obtains this value from the IP
Group, by using the following syntax: param.ipg.<src|dst>.user-
defined.<0>.
The valid value is a string of up to 30 characters.
For configuring Message Manipulation rules, see ''Configuring SIP
Message Manipulation'' on page 311.
Defines a value for the SIP user part that can be used in Message
Manipulation rules configured in the Message Manipulations table.
The Message Manipulation rule obtains this value from the IP
Group, by using the following syntax: param.ipg.<src|dst>.user-
defined.<1>.
The valid value is a string of up to 30 characters.
For configuring Message Manipulation rules, see ''Configuring SIP
Message Manipulation'' on page 311.
Defines the Request-URI host name in outgoing INVITE messages.

[0] No (default).

[1] Yes = The device uses the IP address (or domain name)
defined in the Outbound IP Routing table (see Configuring the
Outbound IP Routing Table on page 427) as the Request-URI
host name in outgoing INVITE messages, instead of the value
configured in the 'SIP Group Name' field.
Note: This parameter is applicable only to Server-type IP Groups.
Defines the routing mode for outgoing SIP INVITE messages.

[-1] Not Configured = (Default) The routing is according to the
selected Serving IP Group. If no Serving IP Group is selected,
the device routes the call according to the Outbound IP Routing
table (see Configuring Outbound IP Routing Table on page
427).

[0] Routing Table = The device routes the call according to the
Outbound IP Routing table.

[1] Serving IP Group = The device sends the SIP INVITE to the
selected Serving IP Group. If no Serving IP Group is selected,
the default IP Group is used. If the Proxy server(s) associated
with the destination IP Group is not alive, the device uses the
Outbound IP Routing table (if the parameter IsFallbackUsed is
