User's Manual
Parameter
Registration Mode
[TrunkGroupSettings_Registrati
onMode]
Version 6.6
Defines the registration method for the Hunt Group:

[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 Hunt 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 Hunt 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 Hunt
Group and configuring the Hunt 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 213).
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 205).
Notes:

If this parameter is not configured, the registration is
performed according to the global registration parameter,
ChannelSelectMode.

To enable Hunt 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 endpoint group includes four FXO endpoints to
register Per Gateway, the device registers all endpoints
except the first four endpoints. The group of these four
endpoints sends a single registration request.
