What is VoIP Telephone Service and What are SIP Trunks?

VoIP Advantage SIP Trunks from Rayfield Communications help businesses to experience real savings on their monthly telephone service costs by using broadband internet connectivity and the latest in Voice Over IP (VoIP) technology.

For years, telephone service has been delivered using dedicated connections. Service to businesses was typically provided through either individual "POTS" lines (Plain Old Telephone Service) or through PRI (Private Rate Interface) circuits. Both of these types of services have been supplied on copper wire connections.

SIP Trunks are, in effect, "virtual" telephone lines. Rather than being provided over low-capacity, low-speed copper wires, SIP Trunks are provided over broadband high-speed data circuits.  Such circuits can be dedicated private circuits or can be shared "public" circuits, such as the internet.

SIP Trunks from Rayfield Communications are delivered over broadband internet connections. This provides high-quality service with the redundancy of the internet behind it. This also results in the best cost savings possible for business telephone service.

SIP Trunks from Rayfield Communications can be used with almost any telephone system. IP-based PBX systems can interface directly to SIP trunks. For legacy analog telephone systems, a "VoIP Gateway" is used to interface between the analog system and the digital SIP Trunks. With either type of system, the cost savings in monthly telephone service will be the same.

SIP Trunks can be used for Local Service, Long Distance Service, and International Service and are great for both small and large businesses and organizations.
