Free calls - you can make on-net free calls. It doesn’t matter who is called or where they are based, if both parties are on the same voice network, the call is free.

Reduced call costs - you can make significant savings with SIP as the cost of calls, including international, is substantially reduced.

Ease of migration - The installation takes less than a day to get up and running.

Scalability - you don’t need to worry about your business outgrowing your telephone system. New extensions and locations can be added to your voice network whenever you wish.

Number provision - you can choose the area code that best suits you. For example, a business that has offices in London, Manchester and Edinburgh can each have a London code.

Number porting - if you need to move premises you don’t need to change numbers. For example, if you are located in London and move to Aylesbury, you can keep your London number. This will save you the time and the cost of producing stationery and notifying clients.
