Management Protocol
Web INI SNMP EMS CLI
This feature supports the pre-emption of IP-to-Tel E911 emergency calls. If the device
receives an E911 call and there are unavailable channels, the device terminates one
of the calls and sends the E911 call to that channel. This feature is enabled by the new
value option, “Emergency” (3) of the existing CallPriorityMode parameter.
Note that this feature is applicable to FXO, CAS, and ISDN interfaces.
28. Combined Support for Digit Map and External Dial Plan File:

This feature provides support for implementing both the Digit Map (DigitMapping
parameter) and external Dial Plan (DialPlanIndex parameter). For example, the Digit
Map can be used for complex digit patterns (which are not supported by the Dial Plan)
and the Dial Plan can be used for long lists of relatively simple digit patterns. In
addition, as timeout between digits is not supported by the Dial Plan, the Digit Map can
be used to define digit patterns (MaxDigits parameter) that are shorter than those
defined in the Dial Plan or left at default. For example, “xx.T” instructs the device to
use the Dial Plan and if no matching digit pattern, it waits for two more digits and then
after timeout (TimeBetweenDigits parameter) it sends the collected digits. Therefore,
this ensures that calls are not rejected as a result of their digit pattern not been
completed in the Dial Plan.
Note: By default, the device first attempts to locate a matching digit pattern in the Dial
Plan, and if not found, then uses the Digit Map.
