HP 89B62AA#AC3 - VVX 250 4-Line VoIP Phone

Overview

The HP 89B62AA#AC3 is an IP telephony endpoint deployed by IT teams in office, contact centre, and cubicle environments to provide managed Voice over IP (VoIP) services on SIP networks. It supports four simultaneous lines and standardised telephony features to address multi-user call handling without reliance on legacy PSTN wiring.

Technically, the phone integrates dual Gigabit Ethernet (RJ-45) ports with Power over Ethernet (PoE) support for network connectivity and power delivery from a single cable. It implements a 2.8-inch colour LCD display (320×240) for call status and menu navigation, and supports a broad set of voice codecs including G.711, G.722, G.729ab, iLBC, and Opus for interoperability with SIP PBX systems.

This model fits on desktops or in smaller office extensions where a full SIP phone with multiple line capability is required. It can also be wall-mounted with included hardware where desk space is constrained.

In deployments, 89B62AA#AC3 integrates with hosted and on-premises SIP platforms such as Zoom, RingCentral, OpenSIP and LDAP directory services. It adheres to 802.1X/EAPoL network authentication, HTTPS/SRTP security, and includes features compatible with directory and configuration services like Zero-Touch Provisioning and Poly device management.

A typical mid-sized office branch can use this device as the primary voice endpoint, or as part of a clustered VoIP deployment with shared call appearance and call park features. The phone should not be deployed as a standalone PSTN replacement without SIP infrastructure, nor in environments requiring DECT/fixed mobile integration, as it lacks cordless or cellular interfaces.
