User's Manual 22. Trunk Group
Parameter Description
[TrunkGroupSettings_Re
gistrationMode]

[1] Per Gateway = (Default) Single registration for the entire
device. This is applicable only if a default Proxy or Registrar IP is
configured and Registration is enabled (i.e., parameter
IsRegisterUsed is set to 1). In this mode, the SIP URI user part in
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 215).
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 204).
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.
