Need to keep your existing analog horns and speakers but want crystal-clear paging from your SIP phone system? The CyberData 011233 SIP Paging Adapter makes it happen in minutes. It turns any standard analog paging amp into a modern VoIP endpoint that handles live pages, multicast announcements, and even a night-time bell ringer. No forklift upgrades, no downtime—just plug-and-play reliability that keeps everyone informed and your IT team smiling. The Telecom Spot Expert Take: In real-world VoIP deployments we see time and again, the biggest headache is making old analog paging work with new phone systems. The 011233 solves it cleanly: two separate SIP extensions (one for pages, one for night ring), built-in multicast support for Poly phones and others, plus smart features like audio buffering for delayed pages and a relay that wakes up your amplifier automatically. It’s compact, rack-mountable, PoE-powered, and secured with TLS 1.2 and SRTP—exactly what IT managers and facilities teams need for offices, warehouses, manufacturing floors, and campuses. If you want zero headaches and rock-solid performance, this adapter is the smart, future-proof choice. Key Features Dual SIP extensions – One handles live paging audio straight from the caller’s handset; the second plays a bell tone as a night ringer when placed in a night-ring group. 10 multicast paging groups – Receive pages directly from Poly phones or any device using standard multicast—no extra servers required. Compatible with almost any analog amplifier – Balanced 600-Ohm page-port output plus audio-controlled relay for remote amp enable. Background music input – Line-in (RCA) lets you pipe music through the system; it automatically mutes during pages. 9 user-uploadable page messages – Store and play custom announcements via DTMF commands. Delayed paging with call buffering – Holds up to four minutes of audio so nothing gets cut off. Security code protection – Prevent unauthorized SIP calls with a simple PIN. Remote amp fault sensor – Triggers alerts or plays a custom message if the amplifier goes down. DTMF zone control – Enter zones on your phone keypad for multi-zone analog paging. Enterprise-grade security & management – TLS 1.2 with mutual authentication, SRTP, HTTPS web config, autoprovisioning, VLAN tagging, and HTTP command interface. Easy rack mounting – Fits standard 19-inch racks with optional kit.
