The ITT-Cortelco Patriot telephone series is a time-honored group of models often found in the hospitality industry and other one or two-line analog business applications. Patriot units feature the proven K-style handset design and a variety of buttons (dependent on model). Patriot phones do not have caller ID.
Please note that message waiting lamps on Patriot phones are 90-volt only, which is available mainly on analog PBX systems. This type of message waiting lamp will not work with phone company voicemail. Nor will it work with a PBX that doesn't support the 90-volt signalling standard.
