The Yealink T48S has been phased out and is no longer available for purchase. The recommended replacement is the Yealink T48U.

Yealink SIP-T48S is an executive IP phone that runs the SIP communications protocol and is supported by major VoIP PBX solutions like 3CX and Broadsoft. The T48S features a beautiful 7" color touchscreen display which integrates the line and soft keys that typically clutter up the phone's face, leaving an elegant desk phone. The T48S includes Yealink Optima HD Voice audio and supports the increasingly popular Opus audio codec, which can adapt to your bandwidth availability to deliver the best audio possible. An RJ9 port allows a wired headset to be plugged in, and an RJ12 port allows you plug in an EHS adapter for wireless headsets or an expansion module for additional keys.

Yealink SIP-T48S includes a USB port for adding Bluetooth or WiFi via a dongle. The VoIP phone has two Gigabit Ethernet ports, so your phone will have fast connectivity for years to come as bandwidth-intensive applications become more prevalent. It supports IPv6. The T48S is a PoE device, so you can power it via the Ethernet cable. Yealink has built in advanced security features like HTTPS provisioning, 802.1X authentication and TLS and SRTP encryption. The handset is now hearing aid compatible. Mount it on the wall using an optional wall mount kit. The package includes a desk stand.
