Version 7.0 465 Mediant 3000
User's Manual 23. Trunk Groups
Parameter Description

[7] Trunk Cyclic Ascending = The channel from the first channel of
the next trunk (adjacent to the trunk from which the previous
channel was selected) is selected.
 [8] Trunk & Channel Cyclic Ascending = The device implements the
Trunk Cyclic Ascending and Cyclic Ascending methods to select the
channel. This method selects the next physical trunk in the Trunk
Group, and then selects the B-channel of this trunk according to the
Cyclic Ascending method (i.e., selects the channel after the last
allocated channel).
For example, if the Trunk Group includes two physical trunks, 0 and
1:

For the first incoming call, the first channel of Trunk 0 is
selected.

For the second incoming call, the first channel of Trunk 1 is
selected.

For the third incoming call, the second channel of Trunk 0 is
selected.
 [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 the parameter is not configured, the Trunk Group's channel
select method is according to the global parameter,
ChannelSelectMode.
Registration Mode
[TrunkGroupSettings_Regis
trationMode]
Defines the registration method of 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 363).
