E.164 conversion
The Comfort Pro S 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 using the “Fixed Mobile Conversion” (FMC) feature as the call number is usually dialled from the
local directory of the mobile telephone being used.
■
When dialling via a computer programme connected with TAPI where call numbers are often already in
the international format due to synchronisation 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”), for point-to-multi-point configuration (“multi-terminal access”)
and for SIP trunks:
