HD Audio
Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology for maximum acoustic performance. Being an open, highly versatile audio codec, Opus, is designed to give a higher HD audio quality than other wideband codecs in a high network bandwidth. However, if your current network quality is poor, Opus can provide you with better audio quality than other narrowband codecs. And its hearing aid compatible (HAC) handset can help people with hearing loss hear voices more clearly.

Efficient Installation and Provisioning
The Yealink T48U supports efficient provisioning and effortless mass deployment with Yealink’s Redirection and Provisioning Service (RPS). The Boot mechanism helps you to achieve the Zero Touch Provisioning without any complex manual settings, which makes the T48U simple to deploy, and easy to maintain and upgrade. Furthermore, a unified firmware and auto-p template that applies to all T4U phone models, saves even more time and costs for businesses, as well as simplifies the management and maintenance.

Secure Transport and Interoperability
The Yealink T48U uses SIP over Transport Layer Security (TLS/SSL), which is the latest network security technology. It’s also compatible with leading soft switch suppliers, such as 3CX, Broadsoft Broadworks, etc. Moreover, it has dual firmware images that give you enterprise-level protection to avoid bricking your system if upgrades fail.
