Traditional/TDM Phone Systems

Convergent Communications sells and supports traditional TDM PBX and key telephone systems for businesses mainly because there are so many still out there. The technology is older but still is widely used today. As VoIP and SIP technologies replaces aging TDM systems, we are uniquely suited to continue in this arena because of our repair and refurbishment facilities.

Our business was founded selling traditional TDM systems in early 2000 and many are still in use today. We sell and support Avaya / Nortel applications and ancillary products like AVST that still work with these older products and will connect disparate systems. IP gateways and other products enable these systems to work with newer VoIP and SIP technologies thus reducing replacement or integration costs.
