parameter IsRegisterNeeded to 1. This is unnecessary for

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.
Serving IP Group ID
[TrunkGroupSettings_ServingIPGr
oup]

by this Hunt 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

ciated 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 119).

are sent to the default Proxy or according to the 'Outbound IP
Routing Table' (see ''Configuring Outbound IP Routing Table''
on page 165).

[TrunkGroupSettings_GatewayNa
me]

[TrunkGroupSettings_ContactUse
r]

and as a user part in From, To, and Contact headers in
REGISTER requests. This is applicable only if the field
