With fixed and mobile telecommunications spend seeing unprecedented growth, businesses are turning to the cloud, not only to cut their costs but to find new flexibility and agility in the way they run their businesses.

ClearSIP, from Vaioni, offers a feature rich alternative to the traditional ISDN that brings with it typical savings of up to 50% on rental and 25% on the cost of calls. But savings aside it is the scalability, extra features and flexibility made possible by SIP that make it so compelling.


One real benefit seen by many organisations is resilience. SIP Trunking gives users the option to take their connectivity from multiple sources, from a dedicated leased line through to the Internet. SIP allows for active and standby circuits, so should one connection fail, the circuit will automatically fail over to the secondary. This level of redundancy is prohibitively expensive with ISDN, but ‘business as usual’ with SIP.


SIP Trunks are highly scalable. Capacity can be adjusted up or down usually without delay and without the contractual penalties of traditional services, meaning businesses can also access ‘bursting’ capability during peak periods

Number Flexibility

SIP trunks allow you to move office and keep your same geographic number without any on-going call forwarding costs or costs associated with new company stationery.

With number flexibility, SIP Trunks help organisations work smarter, using local numbers for advertising and display but routing calls to sales offices anywhere.
