Release:	V2R0.30.0

The Dial Plan feature, intended for inclusion in the OpenStage SIP V2R0 release is a means by which the phone can be given some knowledge of the structure of the numbering plan supported by the server it is registered with. This allows the phone to make intelligent decisions about the numbers dialled by the user which allows it to make the dialling process more efficient in UI terms.

The Dial Plan feature allows an OpenStage phone to determine the completeness of a dialled number so that the phone can start the dialling process without the user explicitly having to select a further option such as “dial” or “OK” after entering the last digit.

Dial plan data may be downloaded directly to a phone via the DLS. The dial plan once loaded on the phone may be enabled/disabled via DLS, WBM or local phone administration. The phone will perform some validation checks on the dial plan data that it receives. If this data is found to be incorrectly for-matted, this will be alerted to the administrator and the data discarded.

Included in the dial plan feature is the introduction of a “dialling mode” option that allows the user to switch between “Hot keypad” and “Context” dialling (see glossary for definition of these terms). This new option will also be applied to the emergency numbers configured within the canonical dial set-tings.

The dial plan will also provide the ability to define numbers which can be dialed when the phone is locked, including wildcards which would allow a range of numbers to be dialed when the phone is locked (E.g. all internal numbers). The existing capability which allows emergency numbers to be defined using the canonical dial settings which overide the phone lock will also be maintained. It may however be a future requirement to differentiate between emergency calls and calls which simply bypass the lock in which case future enhancements may be needed.

Note: There is currently no provision for the support of a digit translation capability (whereby the digits dialled by the user can be converted into a different digit string before being sent to the server).

Note: There is currently no provision for the support of multiple dial plans associated with different servers. In particular, this means that if a phone registers with multiple servers for the purposes of survivability, the dial plan will be applied irrespective of which server is used to route calls. Note: there is no means to automatically ensure that the dial plan data in the phone is correctly syn-chronised with the numbering plan in the server; this needs to be part of the overall administration process.
