SIP trunking is a standards based replacement for traditional carrier services. It connects your telephone system via Internet, broadband, ethernet or private network.
Compared to PSTN & ISDN SIP trunking service is less costly per channel and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and provision and, as standard, it delivers extremely robust business continuity.
The service can support connections ranging from two channels for small phone systems to an unlimited number of channels for large business.
SIP delivers less costly, more reliable connectivity than traditional fixed line services over an IP connection. It can save up to 50% on line rentals and 25% or more on call costs.
SIP trunks are ideal if you are moving, upsizing or downsizing and want to keep your existing numbers. Scale up lines during busy periods and back down again afterwards.
SIP trunks can handle emergencies easily. They are inherently disaster recovery / business continuity ready, letting you reroute calls to an alternative location quickly and easily.
