Description
IP Group, according to the settings in the Account table
(see ''Configuring Account Table'' on page 209).
Notes:

To enable Trunk Group registrations, configure the
global parameter IsRegisterNeeded to 1. This is
unnecessary for 'Per Account' registration mode.

If no mode is selected, the registration is performed
according to the global registration parameter
ChannelSelectMode.

If the device is configured globally
(ChannelSelectMode) to register Per Endpoint, and
channels group comprising four channels is configured
to register Per Gateway, the device registers all
channels except the first four channels. The channels
Group of these four channels sends a single registration
request.
The Serving IP Group ID to where INVITE messages
initiated by this Trunk Group's endpoints are sent. The
actual destination to where these INVITE messages are
sent is according to the Proxy Set ID (see ''Configuring
Proxy Sets Table'' on page 184) associated with this
Serving IP Group. The Request-URI host name 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 (see
''Configuring IP Groups'' on page 179).
If no Serving IP Group ID is selected, the INVITE
messages are sent to the default Proxy or according to the
Outbound IP Routing Table (see ''Configuring Outbound IP
Routing Table'' on page 256).
Note: If the parameter PreferRouteTable is set to 1 (see
''Configuring Proxy and Registration Parameters'' on page
212), the routing rules in the Outbound IP Routing Table
prevail over the selected Serving IP Group ID.
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.
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:

If registration fails, then the user part in the INVITE
Contact header contains the source party number.

The Contact User' parameter in the 'Account Table
page overrides this parameter.
