A normalization rule can be used to strip the digit in brackets to conform to
the expected format for E.164 numbers when using the Converged Office
feature: +31123456789
For more information about Normalization rules, see "Creating Normalization
rules" (page 193) .
Handling numbers called from Office Communicator in E.164 format
requires that the Call Server be configured to ensure that the number
requested is within the defined dial plans:
Within North America
Various types of numbers can be recognized, including international,
national, local (for example, NPA, NXX, and Free Calling Area Screening), or
private, that use one or two access codes and number translators (AC1 and
AC2). The E.164 number that enters the Call Server for Converged Office
calls must be recognizable by the Call Server so that the call can be routed
appropriately. The number is interpreted based upon the access code used
within the called number as it enters the Call Server (AC1 or AC2).
If calls that enter the Call Server are identified as international and outside
of North America (for example, the country code is not 1), the translator
must contain entries that recognize the international numbers and route the
call to the appropriate route list. These entries are generally within the
existing AC1/AC2 translator, as they are used to route international calls that
are dialed directly from telephones.
If calls that enter the Call Server are national or local, the translation used
must recognize numbers with the national dialing prefix (for example,
Converged Office calls) and numbers without the national prefix (for
example, local calls dialed by users). To enable this recognition without
duplication of number plan entries, a Home NPA (HNPA) entry can be added
to the AC1 translator to recognize calls within the local NPA that include
the North American national dialing prefix (for example, 1613 within NPA
613). After matching the HNPA entry within AC1, the translation software
automatically uses the AC2 translator to recognize the rest of the digits
received.
Outside North America
Various types of numbers are recognized, including international, national,
local, or private that use one of two access codes and number translators
(For example, AC1 and AC2) and SPN entries. The E.164 number that
enters the Call Server for Converged Office calls must be recognizable so
that the call can be routed appropriately. The number is interpreted based
upon the access code used within the called number as it enters the Call
Server (AC1 or AC2).
