A SIP paging adapter is the easiest way to modernize any traditional speaker or amplifier by converting it into a full network audio device. Compact, smart, and efficient, devices like the Tonmind SIP-T20 and SIP-T21 make IP audio deployment simple, whether for schools, offices, retail environments, or industrial facilities within an IP PA System.

Key Features

✔ Convert Any Speaker to IP

With a built-in 15W amplifier, the adapter can directly drive an 8Ω speaker or connect to digital/analog amplifiers. It allows existing analog speakers to function seamlessly within a modern IP network.

✔ Multiple Interfaces for Flexible Integration

PoE for one-cable installation

MIC / HST / SPK ports for two-way intercom, external amplifiers, or 8Ω speakers

I/O & Relay ports for connecting IP cameras, alarm systems, door locks and other devices

✔ Cross-System Integration: SIP + ONVIF + HTTP API

The true power of Tonmind’s SIP paging adapters lies in their open-protocol compatibility:

SIP: Works natively with any standard VoIP phone system, PBX, or softphone. Make page calls, conduct intercom conversations, or broadcast messages across zones.

ONVIF: Integrates directly with VMS and NVRs, enabling synchronized audio alerts during security events.

HTTP API & GPIO/Relay Triggers: Automate responses based on external signals, such as triggering a pre-recorded evacuation message when a fire alarm activates.

✔ Compact & Easy to Install

Small size, light weight, PoE power, and simple wiring make the adapter ideal for retrofitting existing audio systems without extra infrastructure costs.

Where It’s Used

SIP paging adapters are widely used in:

Schools & campuses — announcements, schedules, alerts

Offices & commercial buildings — paging, BGM, emergency notifications

Hospitals & healthcare — two-way communication and alarm integration

Warehouses & factories — loudspeaker broadcasting and security alerts

Retail, malls & public facilities — zone paging and CCTV integration

Conclusion

SIP paging adapter is a cost-effective way to transform traditional audio systems into advanced network-based solutions. With powerful interfaces, PoE, and full compatibility with IP PA Systems, they bridge the gap between legacy speakers and modern intelligent audio communication platforms.
