Hi I have a photo of a model of Nortel telephone, and was wondering if someone can, 1, tell me the model number of them ? 2 please tell me if they require KSU or PBX set up for them to work or are they direct plug and play into a wall jack? Also since i do not know how to post photos here please hit the included link to view the photos, thank you.Nortel Phone ID Request
1. What makes you think it's a Nortel phone? If anything possibly an older Northern Telecom phone, I do not fully recognize it however looks like a cross between Vista, Signature and Harmony.
2. Analog phones work on any digital phone system given there is analog card/devices installed. On a phone system the analog ports need to be programmed On a POTs line there is no programming required (Plug and Play)
