Compatibility & Buying Information
Exact NTS Product: This page is for the Htek UC924U Brandable configuration sold under NTS Direct SKU UC924U-BRANDABLE-Z.
Supplied-Generation UC924U: This product page is based on the UC924U configuration represented by the NTS listing and supplied datasheet: 12 SIP accounts, up to 28 paperless DSS assignments, five-way conferencing, dual Gigabit Ethernet, USB 2.0, WFBT60 support, EHS30 support, and UC46 expansion-module compatibility.
Do Not Mix with Newer UC924U Revision: Htek currently publishes an updated UC924U specification with six-way conferencing, incoming 1080p H.264 video, WFBT62 wireless-adapter support, and TLS 1.3. Those newer specifications should not be applied to this NTS listing unless NTS confirms that its physical inventory has changed to the newer revision.
12 SIP Accounts: The supplied UC924U configuration supports twelve SIP registrations for multi-line, multi-extension, and hosted communications environments.
28 Paperless DSS Assignments: The eight physical line keys can provide up to twenty-eight programmable DSS assignments across a four-page view for supported functions such as BLF, speed dial, call park, pickup, shared lines, intercom, and voicemail.
5-Way Conferencing: The supplied-generation UC924U supports local five-way audio conferencing.
Gigabit Ethernet: Dual Gigabit Ethernet ports allow the phone and a connected workstation to share high-speed wired network connectivity.
USB 2.0: The USB port supports compatible USB headsets, USB flash storage, screen savers, wallpapers, and local USB call recording.
Optional WFBT60: The supplied-generation UC924U supports the Htek WFBT60 USB adapter for optional Bluetooth 4.2 or dual-band Wi-Fi connectivity. WFBT60 is sold separately.
EHS30 Support: Htek's EHS30 adapter can be used with supported wireless headset systems requiring electronic hook-switch control.
UC46 Expansion: UC924U supports up to six Htek UC46 color expansion modules. Six modules can provide up to 240 additional programmable DSS assignments for call-intensive reception, administrative, and monitoring applications.
No Built-In Wi-Fi or Bluetooth on This Revision: Wireless connectivity on the supplied-generation UC924U requires a compatible external adapter such as the Htek WFBT60.
Power Adapter Optional: Htek lists the 5V / 1.2A AC power adapter as optional. UC924U can instead receive power from a compatible IEEE 802.3af Class 3 PoE switch or injector.
Wall Mounting: UC924U is wall mountable. NTS Direct lists STAND435-924-926-Z as the dedicated wall-mount accessory shared by the UC924U and UC926U.
NTS Direct Branding: NTS Direct states that Htek phones can be branded with a customer's logo with no listed minimum order quantity. The customer must provide the logo to their NTS Direct sales representative before shipment so the brandable screen can be prepared.
Best Fit: Htek UC924U Brandable is well suited to executives, managers, administrative assistants, reception environments, hosted VoIP providers, MSPs, ITSPs, and other professional users requiring twelve SIP accounts, Gigabit Ethernet, PoE, USB connectivity, extensive programmable functions, optional wireless connectivity, UC46 expansion, remote management, and customer-logo branding.
