User's Manual 17. Control Network
Parameter Description
always-use-source-addr
[IPGroup_AlwaysUseSource
Addr]
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 more information on NAT traversal, see ''Remote UA behind NAT''
on page 149.

Source URI Input
src-uri-input
[IPGroup_SourceUriInput]
Defines the SIP header in the incoming INVITE that is used for call
matching characteristics based on source URIs.
 [-1] Not Configured (default)
 [0] From
 [1] To
 [2] Request-URI
 [3] P-Asserted - First Header
 [4] P-Asserted - Second Header
 [5] P-Preferred
 [6] Route
 [7] Diversion
 [8] P-Associated-URI
 [9] P-Called-Party-ID
 [10] Contact
 [11] Referred-by
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, then 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.
Destination URI Input
dst-uri-input
[IPGroup_DestUriInput]
Defines the SIP header in the incoming INVITE to use as a call
matching characteristic based on destination URIs. The parameter is
used for classification and routing purposes. The device first uses the
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.
 [-1] Not Configured (default)
