IP telephony is a dynamic area with frequent changes in technology; if we go to it now, what assurances are there that our investments wont be lost or stranded in a couple of years?
Vendors have different approaches to IP telephony. The best way to guard against premature obsolescence is to make sure the equipment provider has a history of supporting and upgrading their products in lieu of abandoning them for different technologies. Users should look to the established telephony vendors who have traditionally approached the implementation of telephony services to last 7 years or more. By bringing that knowledge into the data arena, they will be the ones who make sure the investment is long lasting. By utilizing traditional telephony manufacturing and design processes, rather than using PCs or servers for call processing, end-users can expect to avoid the need of replacing server infrastructure every 3 to 4 years.
