In addition, the telephone not only features 29 DSS keys that can be easily programmed for various functions at the touch of a button, but it can also be connected to up to three expansion modules, providing up to 180 additional buttons with an LCD screen and an LED system.
HD audio
Yealink’s Optima HD Voice technology combines advanced hardware and software with wideband technology to deliver optimal audio performance. Opus is a fully open, highly versatile audio codec designed to deliver better HD audio quality than other wideband codecs when network bandwidth is high; However, if your current network quality is poor, Opus still offers better sound quality than other narrowband codecs. And thanks to the hearing aid-compatible (HAC) handset, people with hearing loss can hear voices more clearly.
Efficient installation and commissioning
The Yealink T4U series supports efficient provisioning and effortless large-scale deployment thanks to Yealink’s Redirection and Provisioning Service (RPS) and its boot mechanism. This allows you to achieve Zero Touch Provisioning without complicated manual configurations, making the T4U series easy to deploy, maintain and upgrade. Furthermore, a standardised firmware and an auto-p template applicable to all T4U phone models (T41U, T43U, T46U and T48U) deliver even greater time and cost savings for businesses, whilst simplifying management and maintenance.
Safe transport and interoperability
The SIP-T48U uses SIP over Transport Layer Security (TLS/SSL), the latest technology in the field of network security. It is also compatible with leading softswitch providers, such as 3CX, Broadsoft and Broadworks.
