[4] Descending = Selects the highest available channel. The
highest channel number in the Trunk Group is always first
selected, and if that channel is unavailable, the next lowest
channel is selected.
[5] Dest Number + Cyclic Ascending = The channel is first
selected according to the called number. If the called number isn't
found, the next available channel in ascending cyclic order is
selected. Note that if the called number is found, but the channel
associated with the number is busy, the call is released.
[6] By Source Phone Number = Selects the channel according to
the calling number.
[7] Trunk Cyclic Ascending = The first channel of the next Trunk
(i.e., next to the Trunk from which the previous channel was
allocated) is selected.
Registration mode per Trunk Group:
[1] Per Gateway = Single registration for the entire device
(default). This mode is applicable only if a default Proxy or
Registrar IP are configured, and Registration is enabled (i.e.,
parameter IsRegisterUsed is set to 1). In this mode, the URI
userpart in the From, To, and Contact headers is set to the value
of the global registration parameter GWRegistrationName (refer
to ''Proxy & Registration Parameters'' on page 132) or username
if GWRegistrationName is not configured.
[0] Per Endpoint = Each channel in the Trunk Group registers
individually. The registrations are sent to the ServingIPGroupID if
defined in the table, otherwise 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 (refer to
''Configuring the Account Table'' on page 204).
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 (refer to
''Proxy & Registration Parameters'' on page 132).
If the device is configured globally (ChannelSelectMode) to
register Per Endpoint, and a Trunk Group comprising four
channels is configured to register Per Gateway, the device
registers all channels except the first four channels. The Trunk
Group of these four channels sends a single registration request.
