I'm new to this forum and recently I encured a problem aobut a Cisco UC540 with FXO. The problem sounds like this: Recently I purchased this UC540 and when I tried to 'create new customer site', after completing all cases it prompted for username and password and I don't know them. The equipment is almost new but it has been used before and the previous owner didn't gave me these details. From what I've read on forums (even this one) I have to make a Factory Reset , and I have no clue how to do that.
Can someone give me some advice on how to factory reset a UC540? Or if thee are other ways I would appreciate if you could guide me!
