SIP User's Manual 18. GW and IP to IP
Parameter Description
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 225).
Notes:
To enable Trunk Group registrations, configure the global
parameter IsRegisterNeeded to 1. This is unnecessary for 'Per
Account' registration mode.
If no mode is selected, the registration is performed 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_Servi
ngIPGroup]
The Serving IP Group ID to where INVITE messages initiated by this
Trunk 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 Table' on page 200) associated 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 195).
If no Serving IP Group ID is selected, 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 271).
Note: If the parameter PreferRouteTable is set to 1 (see 'Configuring
Proxy and Registration Parameters' on page 228), the routing rules
in the Outbound IP Routing Table prevail over the selected Serving
IP Group ID.
Gateway Name
[TrunkGroupSettings_Gate
wayName]
The host name used in the SIP From header in INVITE messages,
and as a host name in From/To headers in REGISTER requests. If
not configured, the global parameter SIPGatewayName is used
instead.
Contact User
[TrunkGroupSettings_Conta
ctUser]
The user part in the SIP Contact URI in INVITE messages, and as a
user part in From, To, and Contact headers in REGISTER requests.
This is applicable only if the field 'Registration Mode' is set to 'Per
Account', and the Registration through the Account table is
successful.
Notes:
If registration fails, then the user part in the INVITE Contact
header contains the source party number.
The Contact User' parameter in the 'Account Table page
overrides this parameter.
