SIP Trunking

Many organizations today are seeking the most cost-effective and flexible way to transition to IP-based services. One highly effective strategy is SIP (session initiation protocol) trunking. The business world is talking about how SIP trunking saves money and simplifies your telecom infrastructure. SIP trunking is the next biggest evolution in the telecom industry.

How SIP trunking works

SIP Trunking service provides organizations with a gateway to the public switched telephone network (PSTN) through an IP network. This allows voice calls, whether local or long distance, to run over a single data backbone.

Not only does SIP trunking provide more flexibility and simplicity in managing your network, it also provides the foundation for the deployment of on-premise or network-based unified communication applications, while offering a strong return on your IP technology investments.
