Who Needs PRI Trunks?

If you need a more efficient, smart phone service to meet the growing needs of your business, Comcast Business Trunks is the solution. Our PRI Trunks saves you money by connecting to existing PBX equipment and allows you to maximize your phone capabilities over Comcast's advanced IP network.


How It Works

A trunk is a cost-efficient form of Voice Over IP (VoIP) that leverages a network connection to a Private Branch Exchange (PBX), or digital switch. Each trunk can support up to 184 calls over 23 channels and requires an onsite PBX. Trunking offers additional savings through oversubscription, a concept that operates on a notion that your users will not need the phone at the same time.
