While the telephony industry in the past was primarily led by a small number of carriers and technology suppliers the increasing uptake of VoIP and IP solutions is opening up new telephony markets to a significantly larger group of new solution providers, with different network architectures and various new business models. This means that consumers and enterprises not only have a wider range of products/services to choose from, but also a wider range of organisations from whom these products/services can be bought e.g.

• Traditional carriers
• Internet Service Providers (ISPs)
• Mobile Virtual Network Operators (MVNOs)
• Internet Telephony Service Providers (ITSPs)
• Applications Service Providers (ASPs)

One of the most promising market opportunities for existing and emerging service providers is to replace the traditional customer premise equipment (CPE) based enterprise PBX business with a ‘hosted telephony’ service.

Service Providers can also choose to offer a standalone SIP client (SwyxIt! Now).
