> Compare the Yealink desk phones FieldPulse supports for Engage by how many phone numbers each handles, plus display size, Wi-Fi, and expansion modules.

> **Who uses this:** Anyone with Engage access. **Availability:** Engage add-on · United States and Canada.

This page lists the Yealink desk phones FieldPulse supports for [Engage](https://www.fieldpulse.com/features/engage), grouped into Small, Medium, and Large tiers by how many phone numbers each model handles. Each tier's table also shows the display and notes such as Wi-Fi, Bluetooth, and expansion module support.

## Overview

FieldPulse fully supports setup for the Yealink desk phones listed on this page. Each model connects to Engage over SIP, and each handles a different number of phone numbers, so choose the tier that matches how many Engage numbers you plan to connect to a single phone.

FieldPulse does not currently support video calling, so this list excludes Yealink models with built-in or add-on cameras.

To connect a phone after you buy it, see [Setting Up a Yealink VoIP Phone](/add-ons/engage/yealink-voip) and [Setting Up Engage via SIP (DID)](/add-ons/engage/sip-did).

## Notes & limitations

**Power.** Every model on this page supports Power over Ethernet (PoE), so a PoE-capable network switch or injector powers the phone without extra hardware. No model ships with a power adapter. If your switch does not support PoE, buy a compatible power adapter separately.

**Availability of older models.** Yealink stopped selling the T53W, T54W, and T57W new in June 2026, so stock may be limited and harder to find over time. FieldPulse still supports these models, and they work well if you do not need the Wi-Fi 6, Bluetooth 5.0, or Android features of the T7 and T8 series.

**Other phone brands.** FieldPulse provides full setup support for the Yealink models listed here. Other SIP-compatible phones may work, but FieldPulse can offer only limited, best-effort help with them, and call quality and feature behavior are not guaranteed. For the smoothest setup, buy a listed model.
