The pricing structure of leased lines from our telecom provider was very flexible with no minimums which allowed us to have more freedom when choosing what services were required.
A great benefit we found using these connections was not being charged extra by other providers (eg mobile data) since we used them solely as long distance connections rather than also providing voice communications over IP. There are no downsides associated with this product so far but can see how there may be if they don't continue offering competitive rates! Very good price point - ideal for SMEs who require fast turnaround times between contracts/leases etc.
