identifying my Aastra IP PBX

[pipo]

Hi everybody, I use to install and configure BCM, Norstar and Meridian but recently an office call me to fix their pbx problem and when i came i found a PBX called Aastra install on a pc. The models sip phones that they have is 9133i. I connected the pc on their network and i connect the phones. the pc ask me for login, that i don't know. the phones are booted, i think so cause the screen gave me only the date. So what i want is to download the "Installing Manuals" and the "programming Manuals". ur help would appreciate !!!

Thank you
