The article reports on the benefits of hybrid Internet protocol (IP)/legacy PBX. Network professionals who manage business phone networks combined PBX via IP over private WANs. Converged voice/data T-1s and free inter-company long distance were among key drivers. The hybrid approach is extending into the areas of employee productivity and new applications in some companies. Hybrid IP/time division multiplexing technology voice switches are typically legacy PBX with digital phones and ISDN interfaces that are IP-enabled or gateways that translate voice signals between IP and TDM.
