Voice over IP (VoIP) is digital telephone over a data network, with or without an internet connection; where external calls are made it offers low call costs.
We can provide telephony from a single phone to a larger telephone system with a central PBX for multiple users.
Typically we provide event telephone systems which remain internal for one-to-one or more private communications around an event, but they can be connected to the internet to allow external calls to be made.
