
[11] By 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.
Defines the registration method of the Trunk Group:

[0] Per Endpoint = Each channel in the Trunk Group registers
individually. The registrations are sent to the 'Serving IP Group ID'
if configured in the table; otherwise, it is sent to the default Proxy,
and if no default Proxy, then to the Registrar IP.

[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.

[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 Accounts table (see 'Configuring
Registration Accounts' on page 371).
An example is shown below of a REGISTER message for registering
endpoint "101" using the registration Per Endpoint mode:
