Assessing Carrier VoIP Outsourcing

While Internet Protocol (IP) technology has been utilized in long-haul carrier backbone networks for a number of years, retail Voice-over-Internet-Protocol (VoIP) services are just starting to take hold now. As a result, established and start-up carriers increasingly need to interconnect networks for smooth transmission of IP-based traffic, and must regularly interface VoIP networks with traditional Time Division Multiplex (TDM) networks. The related requirement to support multiple network technologies within and between carrier environments is a daunting reality.

Carriers have long made use of managed or outsourced TDM switch services. The use of outsourced VoIP services can — as a logical extension — be an excellent way to strike a workable balance between smooth service delivery to customers, on the one hand, and maximization of profits (or margins) on the other hand. Provided that an outsourced VoIP service solution is well planned and well managed, carriers can relinquish some responsibilities (for select network functions) in return for better financial results.
