Why replace ISDN with VoIP?
VoIP lines are a fairly new technology that can replace traditional ISDN lines. There are a few reasons to do this. The first are cost savings. Line rental is considerably lower, there are no installation costs or tie-ins when adding or removing lines, and calls to other VoIP users on the same service are free.
There’s another advantage of VoIP. Rather than being limited to fixed groups of numbers in your local area code, you can add as many numbers as you like. These can be in any dialing area, including overseas numbers and non-geographic numbers such as 0845.
You’ll normally have existing numbers that you want to keep. These can be “ported” to your VoIP lines and added to any new numbers you need. Once you’ve done this, you’ve broken free of the constraints of where your telephone lines are physically located. Calls to your numbers can connect anywhere with an internet connection. This makes moving office extremely easy, and is good for disaster recovery: in the event of fire or flood calls can be instantly routed to your disaster recovery site.
