If you have multiple locations,
experience (and logic!) says that a substantial proportion of your
phone calls and data traffic will be from one site to another.
So,
why not have a VPN (virtual private network)?
For example, we acted as telecoms consultants
to provide a UK VPN solution to one particular company with over
20 locations, who now has all calls between branches going free
of charge. Admittedly, there was an up-front cost to set up their
MPLS network, and a monthly running cost, but the annual savings
are hundreds of thousands of pounds.
We have experts who are experienced at
surveying and advising on the connectivity options for corporate
locations, branch offices at home or abroad, and also the
requirements of staff working from home.
