Managers who are happy with a sound, reliable technology investment are unlikely to jump at the chance to adopt the latest and greatest. From a technical point of view, PBX technology is not so much being replaced as it is evolving into a leaner, more flexible, open system that can live on the data network. While there are some legitimate functional and technical advantages provided by IP telephony, there remain some serious technical problems as well. Latency and reliability are the most often cited. Most IP systems do not support large quantities of stations and trunks per server.
Managers are currently unable to differentiate problems between the PC and the telephone.
Because it is still in its infancy, there are few standards governing how all the new technology works together. These standards are being established but are not complete yet. In summary, we believe that traditional PBX technology is proven, reliable, evolving, and here to stay. IP telephony is still unproven and unlikely to overtake traditional telecommunications technology for the foreseeable future. When it happens, TSM and NEC will be there to help you.
