Been trying to find the major difference between these phones. 9122i and 9133i. Mostly I see only the 9133i offers POE and dual Eth ports as compared to the 9112i. Outside of these two is there really any difference? (besides $40) I have a 9133i and like it but it is an expensive phone compared and I do not need the dual ethernet for passthrough nor do I need the POE. I want basically a IP SIP phone to hang in the kitchen and make calls and recieve calls as well as accept Set(__SIPADDHEADER=Alert-Info: ;info=alert-autoanswer) for intercom reasons. Will the 9122i work for this?
Thank you very much.
