E.164 conversion
The Forum 5004/5008/5012 communications system supports two
different types of call numbers when dialling external call numbers. Usually
you enter the code for a route, e. g. a “0” for the “external line” route. Then
you enter an external call number. The external call number can be either a
local area code or a country area code.
The additionally configurable “E.164 conversion” feature enables you to enter
the entire international call number. Using the international call number
makes sense in the following applications:
●
When dialling via a computer programme connected with TAPI where call
numbers are often already in the international format due to synchroni-
sation with a mobile telephone.
●
When importing or comparing directory data when directory entries are in
the international format.
●
When networking communications systems with locations in different
local areas or in different countries.
The “E.164 conversion” analyses an international call number. The analysis
divides the call number into multiple parts: the international area code, the
local area code, the access call number and if necessary the extension. The
call number is respectively abbreviated, eliminating any unnecessary area
codes. The abbreviated call number is then used, e. g. to execute a call.
Configuration
You can configure the “E.164 conversion” feature for each bundle separately.
This is possible for point-to-point configured bundles (“system access with
DSS1”), for point-to-multi-point configuration (“multi-terminal access”) and
for SIP trunks:
