Sixteen SIP accounts, a 7-inch 1024×600 capacitive touchscreen, Android 9 OS, dual gigabit ethernet with PoE, integrated Wi-Fi 5 and Bluetooth 4.2, dual USB ports, optional CAM50 camera for HD video calls. The T58A is Yealink's Android-based executive phone — runs Android apps and supports add-on video.
The T58A is Yealink's first-generation Android executive phone — a 7-inch touchscreen device running Android 9 underneath a Yealink-skinned UI. The Android base unlocks installable apps (Microsoft Teams, Zoom, custom enterprise dialers) and a more familiar touch UI for users coming from smartphone-style devices. The optional CAM50 add-on camera turns it into a one-piece video phone for executive desks.
Where it earns its $349: corporate environments standardizing on Microsoft Teams or Zoom Phone where the user wants both a desk phone and a dedicated video calling endpoint, executive desks where the user values apps and the modern UI, or unified-communications deployments where one device replaces both a phone and a video conferencing endpoint. The CAM50 (sold separately, about $80) clips onto the top — no separate webcam needed.
Where to step up to T58W: $40 more for built-in Wi-Fi 6 (vs Wi-Fi 5 here), built-in camera (no CAM50 needed), and refreshed Android. For new video-enabled executive deployments, the T58W is the better buy. The T58A makes sense when the optional-camera flexibility matters (i.e., not every desk needs video) and the cost savings on non-camera deployments adds up.
Honest weakness: Android adds complexity. App crashes happen. Updates require user attention. Battery life on the screen is not a concern (it is wall-powered) but the responsiveness can lag when too many background apps run. For pure VoIP reliability, the non-Android T57W is simpler and arguably more dependable. Choose Android only if you actually want it.

Plug the T58A into PoE and ethernet. About a minute later it has registered to your extension. Same auto-provisioning flow as every other supported phone — no SIP credentials to type, no firmware to chase.
Boot, fetch config from our provisioning server, register, ready. About one minute on a normal connection.
16 lines per phone. Each line key has a dual-color LED for status at a glance.
Programmable mapped from the voip.army portal — BLF, paging, parking, transfer destinations.
Bringing your own? Send us the MAC, factory-reset, plug in. No charge to add it to the fleet.
Standard PoE — any 802.3af-compliant switch from the last 15 years powers the phone without an adapter.
Tested against every Yealink firmware release for T58A. We catch regressions before they reach your fleet.
