 To set the Dial Plan: (Continued)

Figure 109. Dial Plan Settings

 If the PSTN Trunk Prefix is set to none, ensure

that the Park Extension Prefix does not conflict

with the first digit needed to dial long-distance

calls. For example, if the Park Extension Prefix is

1, then a PSTN call beginning “1-60” is not

completed because the system instead looks for a

parked call at extension 160.

5. Call Appearance mode only—Select the PSTN Trunk

Prefix to determine the digit to have users dial to

access an outside line.

 If you manually assign an extension that overlaps

with the PSTN Trunk Prefix, then dialing an

external call dials that extension instead.

For example: If the PSTN Trunk Prefix = 8, dialing

8-1-6 will ring extension 816.

The PSTN Trunk Prefix should not match the

Default Phone or the Park Extension Prefix.

Results of setting PSTN Trunk Prefix to none:

 A user can dial just by entering the outside phone

number, such as 232-555-0176.

 When auto-assigning extensions, the system skips

all x11 numbers (such as 411, 611, and 911), as

these are used for telephone network services.
