i believe its 21 at 2 digit and when you go to 3 digit it inserts a 2 for 4 it inserts 22...21 is the default on startup so would be 221 and 2221 and 22221..all defualts can be changed
Newer software (R4.0 & higher?) allows you to do a STARTUP when first installing a system and gives the option of renumbering the system to pretty much anything you want. Our office BCM is numbered starting with 100.
I don't know about STARTING with the 100 range, but you can change all your extentions to the 100 range as long as you change the CALL PARK LEAD DIGIT from 1 to something else.
Remember, you can only perform a **startup in the first 15 minutes of the phone system powering up. If it has been over 15 minutes, you will have to power cycle the phone system again.
Nortel starts their DN's with 2xx because 1xx is used for long distance dialing. If a user has a prime line enabled, then picking up the phone to dial an extension beginning with 1-and not pressing the intercom button-would access the long distance carrier.
The Voicemail/callpilot/flash all use DN's/mailboxes 10 100 1000 or 12 102 1002 are permanently assigned and cannot be changed. also ext's from 11-19 111-119? have pre-assigned purposes ( I cannot remember what they are now but a search of threads should show something.) I Had to change the DN Assignments for one customer to get ext 19 to work for them.
