CAUTION:
Any changes made to your dial plan can cause service degradation and
lost calls if not done correctly. Plan all numbering changes with caution.
As an alternative to using prefixed extension numbers (discussed in the
"Pre-
fixed Extension Numbering"
section), a mixed numbering plan will provide simi-
lar functionality. Mixed numbering allows you to use the same first digit for
single-digit dialing, two-digit dialing, and three-, four-, and five-digit room num-
ber dialing.
The following table shows an example of a mixed numbering plan.
