Cortelco ITT-2554NDL-AS telephone

Wall-mount VoIP phone

The Cortelco ITT-2554NDL-AS is a wall-mountable VoIP telephone supplied in an ash finish. It carries model number 255444-VBA-NDL and was first listed by the manufacturer on February 09, 2026. The unit is designed for fixed-location voice over IP communication without a built-in dial pad.

Suited for wall-mounted IP endpoints.

This phone suits installations that need a compact, wall-mounted VoIP endpoint where dialling is handled by an external system or soft client. It is not intended for users who require an integrated keypad, a desktop form factor or handset operation.

No integrated dial pad

The defining specification is the absence of a dial pad, meaning the device relies entirely on external call control or provisioning for placing calls. Buyers must confirm their VoIP platform supports dial-pad-less endpoints before purchasing.
