FAQs
Does the T46S support Bluetooth for headsets?

Troubleshooting
Phone will not power on
Verify that your Ethernet switch provides PoE or ensure the external power adapter is securely connected to a functional outlet.
Audio quality is choppy
Check your network connection and ensure Quality of Service (QoS) is configured on your router to prioritize VoIP traffic.

Setup, Compatibility & Care
Setting up the Yealink SIP-T46S is straightforward. The phone is powered via Ethernet (PoE) using a standard RJ-45 cable, which also connects the device to your VoIP network. If your office switch does not support PoE, you will need to acquire a compatible 5V power adapter. The phone is wall-mountable if desk space is limited. To maintain the device, avoid using harsh chemicals; clean the casing and screen with a soft, slightly damp microfiber cloth. Ensure that firmware updates are periodically performed via your system administrator to maintain security and compatibility with new VoIP features.
