Why NUSO HD Voice?

Put broken audio, echos, muffled voices, and dropped calls behind you with HD clarity. NUSO HD Voice contrasts with standard digital telephony “toll quality” which is comparable to ordinary long distance calls placed over the analog circuit-switched public switched telephone network (PSTN). HD Voice extends the frequency range of audio signals transmitted over telephone lines, resulting in a higher quality sound transmission.

How is HD Quality Achieved?

An HD Voice or wideband audio call transmits audio frequency at a range that’s significantly more in line with the human voice. Today’s HD Voice calls are also delivered over the 4G/5G LTE network rather than the traditional telephone network, ensuring more authentic sound.

HD Enablement for Network Service Providers

How Does NUSO Help Maximize Your HD Voice Experience?

Having HD quality across all connection points can be hard to achieve if there are a number of non-HD connections. With NUSO’s extensive voice peering network, we can provide an HD footprint allowing you to take full advantage of HD Voice.
