[10] Select Trunk by ISDN SuppServ Table = The BRI
port/module is selected according to the settings in the ISDN
Supplementary Services table (see Configuring ISDN BRI
Supplementary Services on page 392), allowing the routing of IP-
to-Tel calls to specific BRI endpoints.
[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
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 for the Trunk Group, then its
channel select method is according to the global parameter,
ChannelSelectMode.
Registration Mode
CLI: registration-mode
[TrunkGroupSettings_Re
gistrationMode]
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
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
Account Table' on page 225).
An example is shown below of a REGISTER message for registering
endpoint "101" using the registration Per Endpoint mode:
