User's Manual 25. Trunk Group
Version 6.8 377 Mediant 500L MSBR
Parameter Description
[9] Ring to Hunt Group = The device allocates IP-to-Tel calls to all
the FXS ports (channels) in the Hunt Group. When a call is
received for the Hunt Group, all telephones connected to the FXS
ports belonging to the Hunt Group start ringing. The call is
eventually received by whichever telephone first answers the call
(after which the other phones stop ringing). This option is
applicable only to FXS interfaces.
[10] Select Trunk by Supplementary Services Table = The BRI
port/module is selected according to the settings in the ISDN
Supplementary Services table (see Configuring Multi-Line
Extensions and Supplementary Services on page 476), allowing
the routing of IP-to-Tel calls to specific BRI endpoints according to
extension number. This option is applicable only to FXS and BRI
interfaces.
[11] Dest Number + Ascending = The device allocates a channels
to incoming IP-to-Tel calls as follows:
a. The device attempts to route the call to the channel that is
associated with the destination (called) number. If located, the
call is sent to that channel.
b. If the number is not located or the channel is unavailable (e.g.,
busy), the device searches in ascending order for the next
available channel in the Trunk Group. If located, the call is sent
to that channel.
c. If all the channels are unavailable, the call is released.
Note: If this parameter is not configured, the Trunk Group's channel
select method is according to the global parameter,
ChannelSelectMode.
Registration Mode
CLI: registration-mode
[TrunkGroupSettings_Regi
strationMode]
Defines the registration method for the Trunk 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 Trunk 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 Trunk 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 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
Registration Accounts'' on page 305).
An example is shown below of a REGISTER message for registering
endpoint "101" using the registration Per Endpoint mode:

Via: SIP/2.0/UDP
