'Always Use Src Address'
always-use-source-addr
[IPGroup_AlwaysUseSourceAddr]
SBC Advanced
'Source URI Input'
src-uri-input
[IPGroup_SourceUriInput]
Parameter Description
This is interworked in to the SIP header as follows:
User-to-User: 00FA080019001038F725B3;en-
coding=hex
Note: To define the Network Node Identifier of the
device for Avaya UCID, use the 'Network Node ID'
(NetworkNodeId) parameter.
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 more information on NAT traversal, see
behind NAT.
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.
