Carrier Quality Calling
The term Carrier Quality Calling is used to describe the audio quality during a phone call. Sound that is routed through the smart phone’s cellular audio channel provides the best possible quality. VOIP (Voice Over Internet Protocol) is the alternative to carrier quality calling, where calls are routed over the smart phone’s data channel.
Audio Channel vs Data Channel
The cellular audio channel delivers the best quality sound under the given circumstances. The cellular data channel, on the other hand, is for surfing the Internet. Cellular data service is “bursty”. A lot of data goes through, but it is not in the form of a continuous smooth flow. Where as cellular voice delivers a lower volume of data in a more continuous and smooth fashion. This results in the higher carrier quality calling.
VOIP Can Be Unreliable on a Smart Phone
Call forwarding services that make use of VOIP can be unreliable. This is most likely to occur when the smart phone is in location that does not provide a strong cellular or WiFi signal. Not being able to understand what a customer is saying or not being able to call them back makes it difficult to provide good service.
Typical Data Usage
Talking using the UberSmartPhone (USP) service makes use of cellular air time minutes. Talking using a VOIP service makes use of cellular data. Though UberSmartPhone (USP) does use a small amount of data to control and setup calls. An inbound UberSmartPhone (USP) call uses 0 bytes of data. An outbound call uses under 500 bytes (0.0000005GB) of data. Multimedia Messages (MMS) use the most data when sending and receiving pictures.
