The Mitel SX 20 Phone System for your Hotel-Motel or Business Office Application.

If your business has this discontinued telephone system and you are looking for replacement components, you have found the right web-site. Even though this system has not been manufactured for many many years now, you will still see them in Hotel-Motels across the country. There is good reason for this. This Model was a very durable telephone system that has held up over the years and is a very effecient telephone system. However when one of the circuit cards fail, you need a reliable source for replacement parts and components. Craig Communiations is your one stop shop for all Mitel cards and components and consoles. All components come with a one year warranty.
