Aiphone Ix-rs-b - IP Audio Room SUB Station SIP Compatible with Privacy Handset Black

Aiphone IX-RS-B IP Audio Room Station SIP

Overview

The Aiphone IX-RS-B is a wall-mountable IP audio endpoint designed for facility intercommunication, lobby desk integration, and emergency broadcast deployment in commercial and industrial environments. This model operates as a SIP-compatible sub-station, drawing only 4.32W via standard PoE (IEEE 802.3af), making it low-impact on network power budgets. The IX-RS-B supports dual audio codecs (G.711 μ-law/A-law and G.722) and full-duplex communication through either a privacy handset or hands-free speaker mode, suitable for reception areas, nursing stations, warehouse call points, and building entry vestibules.

Key Features

• PoE-Only Power (4.32W draw): Operates on IEEE 802.3af class 0 power via a single Ethernet run—no separate transformer, no additional conduit required. This efficient footprint scales across dozens of sub-stations in multi-floor deployments without straining your switch's power budget.
• Dual Audio Codec Support (G.711 and G.722): G.711 (μ-law and A-law) ensures interoperability with legacy PBX and VoIP systems worldwide; G.722 (16 kHz wideband) delivers clearer voice quality over modern SIP networks. Codec negotiation happens automatically during call setup, so you don't need to pre-configure each call path.
• 2W Speaker Output (8Ω load): Built-in speaker provides intelligible alert and announcement volume for small to medium rooms (offices, hallways, small retail spaces). Handset option available for privacy during sensitive calls or for quiet environments where background announcement would interfere.
• Full-Duplex Hands-Free Communication: Switch between handset mode (private conversation) and hands-free speaker operation without call drop or configuration change—useful for multi-person coordination or when staff need free hands during the call.
• SIP and IPv4/IPv6 Protocol Stack: Native SIP signaling integrates with hosted VoIP platforms (Cisco Webex, Microsoft Teams via direct SIP gateway), on-premise IP-PBX systems (Asterisk, FreePBX, Avaya), and hybrid hybrid call routing. Full IPv6 support future-proofs your network infrastructure.
• IEEE 802.1X Port Security: Enforces network-layer device authentication via Ethernet port security, mandatory in regulated environments (healthcare, financial services, government) where device identity on the network must be cryptographically verified before VLAN assignment or call routing.
• Compact Wall-Mount Form (7.6"H × 3.6"W × 2.6"D): Fits into tight corridor spaces, above reception desks, or beside emergency door stations without consuming floor or desk real estate. Mounting bracket included in the package.
• Wide Operating Range (0°C to 40°C / 32°F to 104°F): Suitable for climate-controlled interiors and moderately heated/cooled entry vestibules, but not outdoor or unheated loading docks—verify final placement against site temperature records.
• TCP/UDP, HTTP/HTTPS, DHCP, NTP, SMTP, SFTP Support: Enables time-synced call logging, secure firmware updates, and direct integration with facility management systems and alarm panels for call routing triggered by access events or sensor inputs.
• UL and cUL Compliance (62368-1): Electrical safety certification confirms compliance with North American power equipment standards, a requirement for installation in healthcare facilities, educational institutions, and government buildings.

Integration & Compatibility

The IX-RS-B operates as a SIP endpoint, meaning it registers directly to any SIP proxy or registrar—this includes hosted services, on-premise IP-PBX systems, and hybrid cloud gateways. Call routing is controlled at the SIP level through dial plans, DID assignment, and call forwarding rules. If your facility runs Avaya Communication Manager, Cisco Unified Communications Manager, Asterisk, or a cloud provider like Webex Direct SIP, the IX-RS-B can be provisioned with authentication credentials (username, password, or certificate) to register and receive inbound calls. RTSP streaming is supported for audio-only surveillance or logging scenarios. Port security (802.1X) requires coordination with your network administrator to issue device certificates or assign port-based access control lists before the unit will be granted VLAN access.

Frequently Asked Questions

Q: Can the IX-RS-B work with my legacy analog intercom system?

A: No. The IX-RS-B is IP/SIP native and does not have analog audio or control interfaces. If you need to bridge legacy analog systems, a separate SIP gateway or media converter is required.

Q: Does the IX-RS-B require a separate PoE injector, or will my switch provide power?

A: If your network switch has PoE ports (802.3af or higher), the IX-RS-B will draw power directly from the Ethernet cable—no additional injector needed. Standard PoE switches are sufficient; the unit consumes only 4.32W.

Q: What audio codec should I use for best voice clarity?

A: G.722 wideband codec provides the clearest voice quality on modern IP networks, but both endpoints must support it. If you have legacy SIP devices that only support G.711, the IX-RS-B will negotiate G.711 automatically. For general office use, G.711 is reliable and has universal support.

Q: Is the IX-RS-B suitable for outdoor use in a vestibule?

A: Only if the vestibule is heated and maintains 32°F to 104°F (0°C to 40°C). Unheated or exposed outdoor areas will exceed operating limits and may cause unit failure. No IP rating or weatherproofing is specified.

Q: How do I assign a phone number or extension to the IX-RS-B?

A: The IX-RS-B registers as a SIP user agent. Your system administrator assigns a SIP username, domain, and extension through your PBX or VoIP platform. Call routing is then configured in dial plans or DID tables at the system level, not on the unit itself.

Q: What is IEEE 802.1X, and why does it matter?

A: 802.1X is network port-based authentication—it verifies the identity of the device before allowing it network access. In secure facilities (hospitals, government buildings), this is mandatory. Your network team must configure the switch port and issue certificates or credentials to the IX-RS-B before it will connect.

Ted Perry

The Aiphone IX-RS-B hits a specific gap in facility intercommunication that's often overlooked: you need a SIP audio endpoint that doesn't bloat your PoE budget and integrates cleanly into both legacy PBX environments and modern cloud VoIP. The 4.32W draw—well under the 12.95W cap on 802.3af—means you can deploy a dozen of these across a floor without worrying about power exhaustion on your access switch. The dual-codec support (G.711 for backward compatibility, G.722 for clarity on modern systems) is quietly essential: it sidesteps the codec negotiation headaches that plague mixed-generation deployments. The IX-RS-B model includes wall mounting by default, so corridor and entry-point placement is straightforward.

Technical Highlights:

• 4.32W PoE Draw (IEEE 802.3af class 0): Standard PoE switches deliver this power directly via the Ethernet run—no transformer, no auxiliary circuits. Scales economically to 20+ sub-stations per floor without exhausting your switch's total power budget (typically 380–1000W depending on switch class).
• G.711 and G.722 Codec Support: G.711 (μ-law, A-law) maintains compatibility with any SIP system worldwide; G.722 at 16 kHz wideband cuts voice artifacts and improves intelligibility in noisy environments. Negotiation is automatic—no manual codec assignment per call.
• 2W Speaker Output (8Ω): Sufficient for small offices, reception areas, and nursing station call points. Handset option isolates sensitive conversations and preserves ambient sound in busy spaces—full-duplex switching without call drop.
• 802.1X Port Security: Required in healthcare and government facilities; your network administrator provisions device credentials (certificate or shared secret) before the unit gets VLAN access. Non-negotiable in regulated environments, invisible if your site doesn't enforce it.

Deployment Considerations:

• SIP registration is the deployment pathway—this device does NOT work as a standalone intercom. You must have a working SIP proxy, PBX, or hosted VoIP platform with a valid SIP account, extension, and DID routing already in place. If you're still on analog key systems, this requires a SIP gateway bridge.
• Operating temperature is 0°C to 40°C (32°F to 104°F). Unheated loading docks, exposed entry vestibules, or outdoor alcoves will fail this unit in winter. Verify site climate before committing to wall placement.
• No analog fallback. If your Ethernet connection drops, the IX-RS-B goes silent—there's no onboard battery, no analog handset jack, no emergency bypass. Network redundancy (dual uplinks, UPS on switch) is essential if this is a critical call path (emergency intercom, nursing station alert).

Deploy the IX-RS-B in modern facility call centers, reception desks with active network infrastructure, and healthcare settings where SIP integration and 802.1X enforcement are already in place. It's the right choice for a surgical suite call-in point or a multi-tenant building where each floor gets a sub-station and a central SIP PBX routes calls to the main desk—small, efficient, and codec-flexible enough to coexist with legacy voice equipment via intelligent SIP negotiation.
