Dialing Plan Considerations
When planning a global voice network, remember that the ShoreTel 6.1 system is a
single image system and that you must consider all countries and locations when
designing the international dialing plan.
The ShoreTel 6.1 system can match the dialing plan requirements of the local service
provider for the countries listed within this chapter.
Single-Extension Plan
Across the global voice network, all extensions must be unique and cannot overlap.
Trunk Access Codes
Across the global voice network, when you configure trunk access codes they will
reserve that portion of the dialing plan. Typically in the US, customers use 9 as a trunk
access code as well internationally they often use 0 as a trunk access code.
• Using two different trunk access codes will limit users to only being able to access
certain trunk groups.
• If you use a single trunk access code, some users will need to be retrained.
Operator Digit
The leading digit of 0 is typically reserved for dialing the operator in the US. The
operator digit is configurable.
Emergency Numbers
The ShoreTel 6.1 system allows dialing of emergency numbers with and without trunk
access codes. For this reason, you should reserve the dialing plan space for this feature.
• 911 is used in the US.
• 112 is used in Europe and other countries.
• 000 is used in Australia.
• 999 is used in Asia.
Thus, extensions should not begin with 0, 1, or 9 to make use of this feature.
For more information about emergency numbers, see the appendix about emergency
911 operations in the ShoreTel 6 Administration Guide.
DID Numbers
DID numbers are related to the trunk group in which they are associated. You should
strive to match the last digits of the DID number to the user’s extension number.
