Product Identity

The Yealink SIP-T48S-SFB is a Skype for Business edition IP phone built for office environments that use Microsoft unified-communications platforms. It connects to the network using TCP/IP and weighs 3.65 units.

Suitability

This handset suits organisations that have standardised on Skype for Business and need a gigabit desktop endpoint. Buyers who require support for other UC platforms or who need wireless deployment should look at a different model.

Deciding Specification

The single specification that determines fit is the Skype for Business firmware load. If the deployment uses that platform the phone will provision natively; if the environment runs a different UC system the handset will not operate as intended.

Questions about this item

How does the gigabit Ethernet port perform when the phone is handling a full load of calls and data?

The built-in gigabit port supports TCP/IP traffic at up to 1 Gb/s, so voice packets and network data share the same high-speed link without a separate switch port bottleneck.

Which VoIP signalling protocol does the SIP-T48S-SFB use for call control?

It uses the SIP protocol over TCP/IP for registration, call setup and feature negotiation with the PBX or hosted platform.

What desk space and mounting options does the 3.65 kg unit require?

At 3.65 kg the phone sits securely on a desk without sliding, and the base includes standard wall-mount holes for vertical installation if preferred.
