User's Manual 22. Trunk Group
Parameter Description
the From, To, and Contact headers is set to the value of the
global registration parameter, GWRegistrationName or username
if GWRegistrationName is not configured.

[0] Per Endpoint = Each channel in the Trunk Group registers
individually. The registrations are sent to the 'Serving IP Group ID'
if defined in the table, otherwise, it is sent to the default Proxy,
and if no default Proxy, then to the Registrar IP.

[4] Don't Register = No registrations are sent by endpoints
pertaining to the Trunk Group. For example, if the device is
configured globally to register all its endpoints (using the
parameter ChannelSelectMode), you can exclude some endpoints
from being registered by assigning them to a Trunk Group and
configuring the Trunk Group registration mode to 'Don't Register'.

[5] Per Account = Registrations are sent (or not) to an IP Group,
according to the settings in the Account table (see 'Configuring
Account Table' on page
243 ).
An example is shown below of a REGISTER message for registering
endpoint "101" using the registration Per Endpoint mode:
REGISTER sip:SipGroupName SIP/2.0
Via: SIP/2.0/UDP
10.33.37.78;branch=z9hG4bKac862428454
From: <sip:101@GatewayName>;tag=1c862422082
To: <sip:101@GatewayName>
Call-ID: 9907977062512000232825@10.33.37.78
CSeq: 3 REGISTER
Contact: <sip:101@10.33.37.78>;expires=3600
Expires: 3600
User-Agent: Sip-Gateway/v.6.60A.011.002
Content-Length: 0
The "SipGroupName" in the Request-URI is configured in the IP
Group table (see 'Configuring IP Groups' on page
230 ).
Notes:

If this parameter is not configured, the registration is performed
according to the global registration parameter,
ChannelSelectMode.

To enable Trunk Group registration, set the global parameter,
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.
Serving IP Group ID
[TrunkGroupSettings_Se
rvingIPGroup]
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
230 ).
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
