Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
If the parameter is not configured, these headers are
populated with the device's dotted-decimal IP address of
the network interface on which the message is sent.
By default, no value is defined.
Note: To ensure proper device handling, the parameter
should be a valid FQDN.
'UUI Format'
uui-format
[IPGroup_UUIFormat]
Enables the generation of the Avaya UCID value, adding
it to the outgoing INVITE sent to this IP Group.
■ [0] Disabled (default)
■ [1] Enabled
This provides support for interworking with Avaya
equipment by generating Avaya's UCID value in
outgoing INVITE messages sent to Avaya's network.
The device adds the UCID in the User-to-User SIP
header.
Avaya's UCID value has the following format (in
hexadecimal): 00 + FA + 08 + node ID (2 bytes) +
sequence number (2 bytes) + timestamp (4 bytes)
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.
'Always Use Src Address'
always-use-source-addr
[IPGroup_AlwaysUseSourceAddr]
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 Remote UA
behind NAT.
SBC Advanced
'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
