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.

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.
