Version 7.2 523 Mediant 800B Gateway & E-SBC
User's Manual 23. Trunk Groups
Parameter Description
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.
Used By Routing Server
used-by-routing-server
[TrunkGroupSettings_UsedBy
RoutingServer]
Enables the use of the Trunk Group by a routing server for routing
decisions.
 [0] Not Used (default)
 [1] Used
For more information, see Centralized Third-Party Routing Server on
page 294.
SIP Configuration
Gateway Name
gateway-name
[TrunkGroupSettings_Gatewa
yName]
Defines the host name for the SIP Fro
m header in INVITE messages,
and the From and To headers in REGISTER requests.
By default, no value is defined.
Note: If the parameter is not configured, the global parameter,
SIPGatewayName is used.
Contact User
contact-user
[TrunkGroupSettings_Contact
User]
Defines the user part for the SIP Contact URI in INVITE messages,
and the From, To, and Contact headers in REGISTER requests.
By default, no value is defined.
Note:
 The parameter is applicable only if the 'Registration Mode'
parameter is configured to Per Account
and registration based on
the Accounts table is successful.
 If registration fails, the user part in the INVITE Contact header is
set to the source party number.
 The 'Contact User' parameter in the Accounts table overrides this
parameter (see 'Configuring Registration Accounts' on page 395).
Serving IP Group
serving-ip-group
[TrunkGroupSettings_Serving
IPGroupName]
Assigns an IP Group to where the device sends INVITE messages
for calls received from the Trunk Group. The actual destination to
where the INVITE messages are sent is according to the Proxy Set
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 Groups table (see 'Configuring IP
Groups' on page 365).
Note:
 If the parameter is not configured, the INVITE messages are sent
to the default Proxy or according to the Tel-to-IP Routing table
(see 'Configuring Tel-to-IP Routing Rules' on page 525).
 If the PreferRouteTable parameter is set to 1 (see 'Configuring
Proxy and Registration Parameters' on page 402), the routing
rules in the Tel-to-IP Routing table take precedence over the
selected Serving IP Group ID.
