Does Centrex IP replace the current Centrex offering from the DMS?
No—Centrex IP is an evolutionary service created to enhance your current product rather than replace it. In fact, both Centrex IP and classic Centrex can be delivered side-by-side with complete interoperability and transparency to the user. Although Centrex IP can exist as a stand-alone solution, it can be provisioned alongside TDM-based (classic) Centrex in the same user group. Just like classic Centrex, the SuperNode can handle from one to 50,000 Centrex IP lines.
