Who would have guessed 20 years ago that mobile phones would become as ingrained in our day-to-day lives as they are now?
Since the early ‘90s, handsets have developed enormously and the way we use our phones has changed drastically; however the quality of voice calls really hasn’t changed at all – until now.

Today, Telstra has introduced High Definition Voice calling on the entire Next G® network. HD Voice provides clearer, crisper calls for our customers, as well as suppressing background noise such as traffic or crowds.
So you could be calling a friend in Perth from a train in Melbourne and feel like you’re talking face-to-face.
It’s been an exciting project to develop what is not only Australia’s first HD Voice network, but also the largest HD Voice network in the world.
HD Voice uses state of the art technology known as Wideband Adaptive Multi-Rate coding (WB-AMR) which is a wider audio frequency band than the existing network. This makes sounds sharper, and also means it’s easier for customers to distinguish between similar sounds like ‘S’ and ‘F’.

In the latest video about how to get the most out of Next G® network, wireless engineer Jared King shows us what HD Voice is all about.

Customers with HD-compatible handsets will be able to make HD Voice calls for no extra cost as long as the receiver is also using a compatible handset on the Next G® network.
As it’s a new service, there are currently limited HD-compatible devices available in Australia. However as the demand increases for HD Voice, the number of compatible devices is sure to grow and we expect a large percentage of new devices to support this feature in the coming year.

The Nokia 6720, E52, E72 and N8-00 and the HTC Desire S all support HD Voice today.
Next month, the Sony Ericsson Neo-Xperia will be launched with HD Voice.
