HD audio
Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology for maximum acoustic performance. Being an open and highly versatile audio codec, Opus is designed for higher audio quality than other wideband codecs in a high network bandwidth. If your current network quality is poor, Opus can provide you with a better audio quality than other narrowband codecs. The hearing aid compatible (HAC) handset helps to hear voices more clearly.
Efficient installation and provisioning
The Yealink T43U VoIP/SIP Phone supports efficient provisioning and effortless mass deployment with Yealinkâs Redirection and Provisioning Service (RPS) and Boot mechanism to help you realise Zero Touch Provisioning without any complex manual settings, which makes the T43U simple to deploy and easy to maintain and upgrade. A unified firmware and auto-p template saves time and costs for businesses, as well as simplifying management and maintenance.
Secure transport and interoperability
The Yealink T43U VoIP/SIP Phone uses SIP over Transport Layer Security (TLS/SSL), which is the latest network security technology. It is also compatible with leading soft switch suppliers, such as 3CX and Broadsoft Broadworks. Dual firmware images gives you enterprise-level protection if an upgrade fails.
