Session Initiation Protocol (SIP) sets up, handles and ends sessions over IP networks
Simply put, SIP transfers voice traffic over the same network as your data - with very attractive time and cost savings. And because we've teamed up with companies such as Avaya and Cisco - leading VoIP systems companies - you can depend on the most reliable, high-quality service.
SIP will fundamentally improve the efficiency of communications between organisations and their partners, suppliers, and customers.
Simplify, simplify, simplify
Combining voice and data can transform your entire communications structure. Not only does your system get much simpler, the costs of installation, expansion and support are reduced too.
People have more options available to them today for communicating with each other than ever before, yet they often have a harder time getting through. The selection of choices spans a dizzying array of technologies and devices that can deliver voice, e-mail, instant messaging, and video. Picking up the phone still works, but now users have more choices for deciding how to reach somebody.
Determining the best way to reach someone and managing a contact list can be mind boggling. Simply put, SIP is the glue - and the intelligence - that actually helps improve communications without complicating the issues.
Before SIP and VoIP, companies connected their telephone systems to the public telephone network using traditional carriers such as BT, and paid for them whether they were idle or overflowing and incurred call charges and tariff charges.
SIP trunks enable you to carry voice and data over an IP circuit to the telephone network, rather than through separate circuits.
The IP circuit continues to carry e-mail, Internet, and other corporate traffic as it does today. Voice is simply layered on top of the circuit as another IP application. SIP sets up and tears down voice calls to and from the enterprise over this IP circuit.
Excell uses IP technology to deliver voice, video and data over a single network. If you have a WAN (wide area network) connecting more than one site, you can also save money by using VoIP for calls between them. For more information, see our hosted solutions.
