| These phones have two modes of operation, an ITP mode which is Inter-Tel specific, and a SIP mode which could work with other services etc. This is if you are running the IT5000/Axxess firmware on them. If you could acquire, or for that matter if they are already running the IT7000 firmware for the phones it would make them SIP only and would give you a lot better chance of them working on other SIP based services and soft switches.
Your probably much better off getting a phone that is suggested by the service provider though. |
