New telephone numbering scheme in Greece (Phase 1) (750104)

MORE INFORMATION

Telephony API (TAPI) allows you to configure dialing rules for all telephony programs. One of the features of Windows Telephony is the ability to automatically use the correct outside line access codes, long distance and international prefixes, and other dialling rules based on your location and the destination of the telephone call.

On 20th January 2002 Greece will begin using a new telephone numbering scheme. You can find more information by visiting the National Telecommunications and Post Commission webpage at: The new numbering scheme is described in:

(in Greek) or (in English).

Microsoft recommends that all users operating from locations inside Greece should configure all their dial-up connections not to use Dialing Rules at all. In that case the user will have to provide the whole "dialable" number for example "0106151300" or "0965077777". This dialing format will work regardless of the location of the call initiator relative to the location of the call recipient. That is, the area code is dialed at all times regardless if the call is local or long-distance.
