VoIP New Telephone System Information


Telephone Features

The majority of the phones deployed by PCS are Aastra 33is. A small number of phones installed during the initial phase were the Aastra 9133is. The models are, technically speaking, not significantly different from one another, but the icons on the phone nameplate look different from one another.

Which model of VoIP phone do I have?

The Aastra 33i phone has the letters "33i" to the right of the arrow navigation keys. (The 9133i does not.)

Relevant pages extracted from User manuals for Aastra 9143i/33i and 9133i phones:
