6 – 10 ShoreTel, Inc.
On-Net Dialing
ShoreTel 6.1 supports On-Net Dialing, an enhancement that allows users to create more
flexible dialing plans than before. In contrast with previous releases which could only
support a "flat" dialing plan and treated all numbers as a single, indivisible unit, the
On-Net Dialing feature allows users to divide phone numbers into two separately-
managed parts:
• extension prefix - typically 3 digits in length; similar in concept to a site code
• user extension - typically 4 digits in length; acts as the number you would dial to
reach other users in your organization
By dividing phone numbers into two parts, the On-Net Dialing feature provides
customers with a more seamless method of migrating from their legacy phone systems
to the newer ShoreTel system. The On-Net Dialing feature allows customers to preserve
their existing dialing plans when integrating ShoreTel equipment with their legacy
equipment. While previous releases allowed customers to integrate ShoreTel equipment
with their legacy PBX, the configurations needed to maintain the customer's existing
Prepend this Dial Out Prefix The Dial Out Prefix is prepended to the number.
This feature is typically used when connecting
the ShoreTel 6.1 system to a legacy PBX system
using the ShoreGear-T1 voice switch. The Dial
Out Prefix enables the ShoreTel 6.1 system to
seize a trunk on the legacy PBX. The Dial Out
Prefix is not applied to Off System Extensions.
Not applicable.
Vertical Service Codes If a Vertical Service Code was dialed, digit
manipulation rules do not apply.
Vertical Service Codes work with ISDN PRI
trunks and some loop-start trunks.
• With PRI trunks, Vertical Service Codes for
Caller ID Blocking control will be
converted to D-Channel messages.
• With loop-start trunks, the service
provider must be able to accept the
outpulsed digits with only 50 msecs of
pause between each digit, including the
service codes.
Vertical Service Codes are typically not
supported by service providers on wink-start
trunks. If you have outbound access on wink-
start trunks and you dial a vertical service code,
you will likely get an error message from the
service provider.
Not applicable.
Off System Extensions Off System Extensions define ranges of
extensions that when dialed will be routed out
of this trunk group. This is typically used to
interface to a legacy PBX system using the
ShoreGear-T1 or ShoreGear-E1 voice switch.
Off-system extensions digits can be manipulated
using a translation table.
Digit manipulation, including the Dial Out
Prefix, will not be applied to these calls.
Not applicable.
