SIP, or Session Initiation Protocol, is an advanced form of voice communications. Traditional telephone calls are converted to SIP, a VoIP standard that allows your phone calls to be delivered and transferred across data networks, both public and private.

More and more businesses are moving over to SIP as their preferred means of communication.

There are a number of advantages.

Portability – SIP does not suffer from the usual restrictions of normal phone lines and local telephone exchanges. Your telephone calls can be delivered to any location that has an adequate data connection and network arrangement.

Resilience – SIP calls can be delivered to multiple locations, either consecutively or as back-up. This allows your telecoms to fit within the disaster recovery arrangements you may have in place for your data services.

Flexibility – VoIP and SIP allows you to deploy a multitude of devices, from desk telephones to soft IP phones on laptops, to the latest mobile apps and multimedia devices.

Mobility – SIP-based systems now support apps for smartphones and tablets and can be delivered over WiFi, 3G and 4G mobile networks, allowing you to revolutionise the way your staff communicate in the office and when working away and/or from home.

Cost – Telephone line rental costs typically cost half that of digital ISDN telephone lines, and with preferred call rates from Southern Communications, the overall running costs of your telephony will be significantly reduced.
