Voice is not dead! The last few years have seen a dramatic increase in the total amount of time that people spend talking to each other. What is changing is how they communicate. A voice call can now take many forms, from a simple telephone call on a home phone, to a call placed on a mobile phone, to a call made on a PC entirely handled by the Internet. Ensuring that a core network can evolve with users' voice needs is critical to future success.

As networks evolve to meet new requirements, there are common themes that must be addressed:

Mobile Voice Consolidation– Mobile Service Providers have a unique set of challenges that involve not only handling traditional mobile voice calls, but increasingly those voice calls must compete for resources with data and video calls and fixed-mobile-convergence (FMC) calls. Effectively using All-IP networks, increasing bandwidth efficiency and improving reliability are keys to succeeding in this consolidation.

PSTN Consolidation – Customer demand for new services offers an exciting opportunity to build new sources of revenue and reverse competitive losses. By taking existing technologies and deploying them in new ways, Service Providers can offer innovative solutions that provide benefits to both consumer and business users, while also improving reliability and reducing operating costs.
