Dialing Plan Define Digit Manipulation
911 calls are routed out of the local site’s associated trunks. If there are no 911 trunks available at the
local site, the call is routed via the designated proxy site.
Explicit Carrier Selection (101xxxx) Dialing
The ShoreTel system supports explicit carrier selection. If the user dials an access code followed by
“101,” the next four digits collected are for explicit carrier selection (101xxxx). The carrier information is
retained and passed to the trunk.The digits collected are treated as unroutable calls; the digits are
routed “as-is” out either local site or proxy site trunks only.
Operator-Assisted (0, 00) Dialing
The ShoreTel system supports operator-assisted dialing. If the user dials an access code followed by
“0x,” digit collection is terminated after a brief timeout and the call is routed to a trunk.
Vertical Service Code (*67, *82) Dialing
The ShoreTel system supports some vertical service codes for feature activation. If the user dials an
access code and then the star (*) button, the system collects the subsequent digits and then
terminates after a brief timeout. The digits collected are treated as unroutable calls — they are routed
“as-is” out either local site or proxy site trunks only. If the trunk is a PRI or SIP trunk, the trunk strips
and interprets *67 to block outbound Caller ID, and *82 to unblock outbound Caller ID.
End Digit Collection (#)
In some cases, digit collection ends after a timeout period. To bypass the timeout and immediately
send the call, the caller presses the (#) button.
Define Digit Manipulation
Once the route decision has been made, the call is passed to the trunk. The dialed number, which is
normally passed within the system in canonical format, is examined and manipulated based on the
trunk group configuration. This ensures that the number can be properly received by the service
First, the trunk access code dialed by the user is removed. If the number is in canonical format, which
is local, long distance, ERC, or international, digit manipulation can occur. If the number is unroutable,
which is n11, ECS, operator, and vertical service code numbers, digit manipulation, other than the dial-
out prefix, is not applied.
