Let’s pretend we’re building a PBX from scratch. We want extensions 6000-6999 to be local extensions. We also want extensions 7000-7099 to route to Palo Alto via POTS or T1, and the DID number there would be (212) 980 70xx.
Step 1: “change dialplan”
Uniform Dialing Plan
4-digit, Search
local-extensions-first
For first digit 6, length 4, put
extension
For first digit 7, length 1, put
misc
Step 2: “add second-digit 7”
Digit: 0, Identification:
extension, Length:
4
Step 3: “change udp x”
Go to page 2
Where it says 6x, put
Local
Where it says 7x, put
AARCode 225
Step 4: “change aar analysis x”
Dialed String
225, Min
6, Max
6, Route Pattern
100, Call Type
aar
Step 5: “change route-pattern 100”
Assume that you want the call to go out over your T1, which is trunk 8. Let’s also assume you want any phone in your office to be able to call that office.
Group #
8, FRL
0, # Deleted Digits
3, Inserted Digits
12129807
That’s it!
You can get a little more of the theory from section 4.3 (starts on page 11) of this link:

make sure you copy the route-pattern settings from a different route that Avaya configured for this… you will need a different Group/Trunk # (most likely) and you probably don’t want to give FRL 0.
