Parameter Description
parameter ChannelSelectMode (refer to
''Configuring Proxy and Registration Parameters''
on page
147 ).
ƒ
If the device is configured globally
(ChannelSelectMode) to register Per Endpoint,
and a Hunt Group comprising four FXO endpoints
is configured to register Per Gateway, the device
registers all endpoints except the first four
endpoints. The Hunt Group of these four
endpoints sends a single registration request.
Serving IP Group ID
[TrunkGroupSettings_ServingIPGroup]
The Serving IP Group ID to where INVITE messages
initiated by this Hunt Group's endpoints are sent.
The actual destination to where these INVITE
messages are sent is according to the Proxy Set ID
(refer to ''Configuring the Proxy Sets Table'' on page
148 ) associated with this Serving IP Group. The
Request URI hostname in the INVITE and
REGISTER messages (except for 'Per Account'
registration modes) is set to the value of the field
'SIP Group Name' defined in the 'IP Group' table
(refer to ''Configuring the IP Groups'' on page
152 ).
If no Serving IP Group ID is selected, the INVITE
messages are sent to the default Proxy or according
to the 'Tel to IP Routing Table' (refer to ''Configuring
the Tel to IP Routing Table'' on page
201 ).
Note: If the parameter PreferRouteTable is set to 1
(refer to ''Configuring Proxy and Registration
Parameters'' on page
147 ), the routing rules in the
'Tel to IP Routing Table' prevail over the selected
Serving IP Group ID.
Gateway Name
[TrunkGroupSettings_GatewayName]
The host name used in the SIP From header in
INVITE messages, and as a host name in From/To
headers in REGISTER requests. If not configured,
the global parameter SIPGatewayName is used
instead.
Contact User
[TrunkGroupSettings_ContactUser]
The user part in the SIP Contact URI in INVITE
messages, and as a user part in From, To, and
Contact headers in REGISTER requests. This is
applicable only if the field 'Registration Mode' is set
to 'Per Account', and the Registration through the
Account table is successful.
Notes:
ƒ
If registration fails, then the userpart in the
INVITE Contact header contains the source party
number.
ƒ
The 'ContactUser' parameter in the 'Account
Table' page overrides this parameter.
