Working on a ESI 50 that has 300 extension number plan.
How can i change that to 100 extension number plan.
Thanks

And you're ready to initialize the system?

It's an installer function that requires a restart, wiping programming. (169)

Yes initialize twice, from a phone. Do i need to use esi software programming ?

Carl. Not sure how i got to that function, but it did reset to ext 100 and up.
Thanks gary s.
