Version 7.2 507 Mediant 500L 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_UsedB
yRoutingServer]
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 289.
SIP Configuration
Gateway Name
gateway-name
[TrunkGroupSettings_Gatew
ayName]
Defines the host name for the SIP From 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_Conta
ctUser]
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_Servin
gIPGroupName]
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 363).
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 509).
 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.
