Legacy Comdial Product Support

Since the early 1990’s, C & M Telephone sold and installed the Comdial line of Telephone systems. The early 2000’s saw Comdial and other brands come into the Vertical Communications family. Eventually the older products where no longer manufactured. Many Comdial systems are still in service and C & M Telephone is committed to keeping the current systems supported with spare phones, system repairs and documentation. If you have a Comdial system in Connecticut or Western Massachusetts and are in need of service or support, please contact us. If you need copies of programming and user guides, see the links below.
