Voice over Internet Protocol, similar to cellular networks, is handled digitally. Ringback is one way in which VoIP is setting itself apart from traditional telephony services. When you subscribe to business VoIP, your phone will most likely come pre-programmed with both ringback and on-hold music. VoIP providers, unlike cell phone carriers, don’t charge extra for ringback tones. Not only that, you can upload your own custom ringback and on-hold music, such as a favorite song, a customized soundtrack, or even a customized greeting or up-sell message. VoIP subscribers can select different connect and on-hold music by accessing their online portal.
