DESIGNED FOR BUSINESS
The Yealink SIP-T48U is designed for executives and professional users who manage multiple calls, extensions and telephone functions throughout the working day.
Its large 7-inch colour touchscreen provides an intuitive interface for line selection, call history, directories, settings and programmable functions.
The 800 × 480 display allows users to move between pages and applications quickly without relying on physical paper labels.
Twenty-nine programmable touchscreen keys can be assigned to lines, monitored extensions, contacts, speed dials and call-management features.
Up to sixteen SIP accounts can be configured, allowing the phone to support multiple extensions, telephone numbers or service providers where permitted by the connected platform.
Busy Lamp Field and presence indicators allow suitable extensions to be monitored before a call is placed or transferred.
Yealink Optima HD Voice combines wideband codecs, professional acoustic hardware and audio processing to support clear conversations.
Yealink Acoustic Shield and Smart Noise Filtering help reduce unwanted office noise transmitted to the other caller.
A full-duplex speakerphone with acoustic echo cancellation allows both participants to speak naturally during hands-free conversations.
The handset uses a Hall-effect switch rather than a conventional mechanical hook switch, helping provide quiet and reliable on-hook detection.
The handset is hearing-aid compatible for users with suitable hearing devices.
Call functions can include hold, mute, transfer, forwarding, Do Not Disturb, call waiting, call pickup and call parking.
The phone supports local conferencing with up to ten participants, subject to firmware and telephone-platform configuration.
Directory support can include local contacts, remote XML phonebooks, LDAP and synchronised provider directories.
Two USB Type-A ports provide accessory flexibility for compatible USB headsets, storage devices and Yealink accessories.
USB call recording is supported when a suitable storage device, firmware and telephone-platform configuration are used.
Optional Yealink Wi-Fi dongles allow the phone to connect to a compatible wireless network where Ethernet cabling is unavailable.
Optional Yealink Bluetooth dongles support selected compatible wireless headsets and mobile-device integration.
Wi-Fi and Bluetooth are not built into the phone and require the correct optional USB accessories.
The dedicated RJ9 headset connection supports compatible professional wired headsets using the correct connection cable.
Electronic Hook Switch support is available through compatible Yealink accessories for selected wireless headset systems.
The phone supports the Yealink EXP43 expansion module, adding up to sixty additional programmable functions per module.
Up to three compatible EXP43 modules may be supported, subject to firmware and power requirements.
Dual Gigabit Ethernet ports allow the phone to connect to the network while providing a pass-through connection for a nearby computer.
IEEE 802.3af Power over Ethernet allows the phone to receive network data and electrical power through one Ethernet cable.
Where PoE is unavailable, the phone can be powered using an optional compatible Yealink 5V/2A mains adapter.
The adjustable desktop stand provides two viewing positions for different desk layouts and seating arrangements.
The phone can also be wall mounted using the appropriate compatible Yealink mounting accessory.
The phone requires a compatible SIP account, hosted telephone service or IP-PBX configuration. These services are not included with the hardware.
