Core Technology & Architectural Design
At its heart, the Avaya 700411176 is built upon a foundation of superior digital signal processing (DSP) and meticulous acoustic engineering. It operates on standard SIP (Session Initiation Protocol), ensuring broad compatibility with a wide range of IP telephony systems, including Avaya Aura Communication Manager, IP Office, and many third-party SIP-compliant platforms.
Audio Processing & Microphone Array
The phone's exceptional performance stems from its sophisticated audio capture and reproduction system.
Beamforming Microphone Technology
The unit features a high-precision, 360-degree beamforming microphone array. This technology actively forms focused audio "beams" towards each speaker around the table, dynamically tracking and enhancing voice signals while simultaneously suppressing ambient noise, air conditioning hum, and keyboard clicks. This ensures every participant is heard clearly, regardless of their seating position.
Full-Duplex Acoustic Echo Cancellation (AEC)
Advanced AEC algorithms completely eliminate acoustic echo and prevent howling or feedback. This full-duplex capability allows for natural, simultaneous conversation—people can interrupt or speak over each other without audio clipping or loss, mirroring the dynamics of an in-person meeting.
Wideband Audio Support
Support for wideband audio (G.722) extends the frequency range of transmitted sound compared to traditional phones. This results in richer, more lifelike voice quality, making it easier to discern subtle tonal differences and consonants, thereby reducing listening fatigue and improving comprehension.
Network Integration & Management
As a dedicated VoIP endpoint, the 4690 is designed for seamless integration into enterprise networks.
Dual Gigabit Ethernet Ports
The device includes two 10/100/1000 Mbps Ethernet ports. The primary port connects to the LAN (and ultimately to the IP PBX), while the secondary port provides a pass-through connection for a desktop computer, allowing both devices to share a single network drop without requiring an additional switch. This built-in switch supports VLAN (IEEE 802.1Q) tagging for prioritizing voice traffic and maintaining network segmentation.
Power over Ethernet (PoE) Compatibility
The Avaya 700411176 supports IEEE 802.3af PoE (Class 2). This allows it to receive both power and data over a single Ethernet cable from a compatible PoE switch or injector, simplifying installation, reducing cable clutter, and enhancing reliability by centralizing power backup.
Quality of Service (QoS) & Security
Configurable QoS settings (Layer 2: 802.1p/Q, Layer 3: ToS/DSCP) ensure voice packets are prioritized across the network, minimizing jitter and latency for consistent call quality. For security, it supports secure call signaling (TLS) and media encryption (SRTP), as well as HTTPS for secure web-based management.
Hardware Design & User Interface
The physical design of the Avaya 4690 IP Conference Phone is both aesthetically professional and functionally intuitive, built for ease of use by all meeting participants while being managed by IT administrators.
Control Panel & Display
The sleek, low-profile unit centers around a user-friendly control interface.
Graphical LCD and Navigation
A backlit, high-contrast graphical LCD provides clear visual feedback of call status, participant lists, directory information, and menu settings. It is flanked by context-sensitive soft keys and a 4-way navigation cluster with a central "OK" button for intuitive menu browsing and feature activation.
Dedicated Function Keys
The phone features a dedicated keypad for dialing, along with hard keys for essential functions like Speakerphone, Mute, Volume up/down, Headset mode, and Conference. The prominent, illuminated Mute key provides an unambiguous visual indicator (red LED) when the microphone array is disabled, a critical feature for confidential discussions.
Connectivity & Expansion
The device offers comprehensive connectivity options to integrate with various audio peripherals.
External Audio Ports
For expanded functionality, the 4690 includes multiple standard ports: Headset Port (3.5mm): For private listening or a lavalier microphone. Line Out (3.5mm): Connects to external amplifiers or recording devices. Line In (3.5mm): Allows integration of auxiliary audio sources, such as a laptop playing a presentation soundtrack or a secondary wireless microphone receiver.
Expansion Microphone Support
A critical capability for larger rooms is support for daisy-chaining up to two optional Avaya expansion microphones (4691A). These units extend the effective pickup range of the system, ensuring clear audio capture in boardrooms or spaces up to 20 feet in length without degradation in quality.
Primary Use Cases & Application
The Avaya 700411176 4690 IP Conference Phone is not a one-size-fits-all device; it is targeted at specific environments where communication clarity and reliability are non-negotiable.
Executive Boardrooms & Formal Meeting Rooms
In executive settings, the phone serves as the central audio hub for strategic discussions with remote stakeholders, quarterly earnings calls, and high-level negotiations. Its premium audio quality ensures leadership is presented clearly and professionally, while its discreet, elegant design complements high-end furnishings.
Critical Boardroom Features:
Superb Audio Fidelity: Ensures every word from the CEO or CFO is transmitted without ambiguity. Expansion Microphone Ready: Catches comments from all attendees around a large table. Strong Security Protocols: Protects sensitive conversations with encryption.
Medium to Large Conference Rooms
For departmental meetings, project reviews, and training sessions involving 6-14 participants, the 4690's 360-degree pickup and powerful speaker provide an inclusive audio experience. It connects seamlessly to room video systems for a combined audio-visual solution.
Dedicated Video Conferencing Suites
When paired with a video codec or UC software (like Microsoft Teams Rooms or Zoom Rooms), the 4690 acts as a far superior alternative to the built-in microphones and speakers in most displays or soundbars. It provides consistent, room-filling audio for both ends of the call.
Integration Consideration:
Using the analog Line In/Out connections, the 4690 can be integrated into broader AV systems, accepting audio from a video switcher and sending audio to ceiling speakers, providing a flexible, hybrid audio backbone.
Category Context & Comparison
Within the landscape of conference phones, the Avaya 4690 IP Conference Phone occupies a distinct position.
Within the Avaya Portfolio
It sits above the smaller 4600 series desk phones and the more basic conference phones, offering a dedicated, superior acoustic experience for rooms. It is often compared to the larger Avaya Conferences (B149) all-in-one system, with the 4690 being a more network-integrated, SIP-native solution versus the B149's focus on analog and wireless connectivity.
Key Differentiators from Desk Phones:
Unlike a desk phone with a built-in speakerphone, the 4690 is engineered from the ground up for multi-participant, omni-directional audio capture in an acoustically challenging room environment. Its DSP algorithms, microphone array, and speaker power are all significantly more advanced.
