8 [SITECODE] Extension Number

8 80 2100
8 81 2100

80 = Texas
81 = Arizona

Route Patterns

80.2XXX
81.2XXX

Called Party – Predot Strip

= Solution for overlapping dial plans

With a centralized model, we would solve overlapping extensions using CSS and Partitions

How to deal with Intrasite calling when in 1 single cluster? (CENTRALIZED) Use a Translation Pattern with the Site Code approach of 81.2XXX to Called Party of 2XXX. (With PreDot strip)

TP can be assigned its own CSS for inbound calling. Whatever the TP changes the digits to, it will then search this CSS for them. IMPORTANT!
