User's Manual
IsRegisterNeeded to 1. This is unnecessary for 'Per Account'
registration mode.

If the device is configured globally to register Per Endpoint and an
channel group includes four channels to register Per Gateway, the
device registers all channels except the first four channels. The
group of these four channels sends a single registration request.
Assigns an IP Group to where INVITE messages received from this
Trunk Group are sent. The actual destination to where these INVITE
messages are sent is according to the Proxy Set ID associated with
the 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 'SIP Group Name' parameter configured in
the IP Group table (see 'Configuring IP Groups' on page 214).
Notes:

If this parameter is not configured, 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
323).

If the PreferRouteTable parameter is set to 1 (see 'Configuring
Proxy and Registration Parameters' on page 228), the routing
rules in the Outbound IP Routing table take precedence over the
selected Serving IP Group ID.
Defines the host name for the SIP From header in INVITE messages
and for the From/To headers in REGISTER requests.
Note: If this parameter is not configured, the global parameter,
SIPGatewayName is used.
Defines the user part for the SIP Contact URI in INVITE messages
and for the From, To, and Contact headers in REGISTER requests.
Notes:

This parameter is applicable only if the 'Registration Mode'
parameter is set to 'Per Account' and registration through the
Account table is successful.

If registration fails, the user part in the INVITE Contact header is
set to the source party number.

The 'Contact User' parameter in the Account table overrides this
parameter (see 'Configuring Account Table' on page 225).
Defines a name for the Trunk Group. This name represents the
Trunk Group in the SIP 'tgrp' parameter of the outgoing INVITE
messages (according to RFC 4904). For example:
sip:+16305550100;tgrp=TG-1;trunk-context=+1-
630@isp.example.net;user=phone
The valid value can be a string of up to 20 characters. By default, no
name is configured.
Notes:

If this parameter is not configured, the Trunk Group decimal
number is used in the SIP 'tgrp' parameter.

This feature is enabled by any of the following parameters:

UseSIPtgrp

UseBroadsoftDTG

Currently, this parameter can only be configured using the ini file.
