I am looking for some assistance on how to troubleshoot why an phone isn’t connecting properly. We have an Aastra 480i and it seems no matter what I do - it’s not connecting (I get the person at extension 200 is not available).
We have other Aastra’s and I have been able to get those up and running - but for some reason this one won’t. This is a system I have inherited by the way - and not much documentation exists.
Not even sure where to start with this one since I am new to Aastra.
Any help - advice - direction is appreciated.
