I have a user who was complaining she needed a new phone - the LCD was scratched. We gave her a new phone, an Avaya 9611G. Plugged in the phone and it has a different Extension ID of course, that was pointing to a different user extension - presumably the one that the phone was initially setup to use. So I was trying to determine if I should change this new phone's Extension ID to point to her original phone's Base Extension? Her other, now tossed phone, Extension ID is still in there and still pointing to her Base ID. However, I am stuck on how does the system even "attach" an system Extension ID to a phone? Once an Extension is assigned, how does the system continue to associate that phone w/that Extension ID? Is it by Mac? I tested the idea of it being a physical port with my own phone - *36 and plugged it into a different LAN port and it connected fine w/o any changes so that leads me to think it is not a physical port; which is why I am asking.
When a phone is disposed, should I delete the extension that was assigned to it so it gets re-assigned?
I am obviously new to all this so please excuse my ignorance.
Thanks
