Because VOIP only relies on an existing broadband connection, Tom can add an additional handset for his assistant by simply plugging in a new VOIP phone. We took care of all the configurations so the VOIP phone truly plugged and play. VOIP also gave Tom access to cheaper call rates and line rental compared to BT, particularly where his international calls were concerned. Finally, Tom also has the choice of keeping his two phone lines separate from each other or we can connect the two together for full interconnectivity between his existing phone number and his new VOIP phone.
