Partner document accessThe selected speaker is an IP audio endpoint on the site LAN. An operator console and compatible audio platform provide the announcement workflow; mounting and coverage are designed for the application.

Scroll across the diagram to explore each connection.

The operator addresses the configured destination through a compatible SIP platform. Confirm audio codecs, registration and paging behaviour during commissioning.
Where the selected model lists RTP multicast, a compatible sender distributes audio to configured receiver groups. This is separate from SIP call registration.
Photographs show actual SipTok models. This is a conceptual connection diagram; cable routes, power and final equipment are confirmed during system design.

Ask a product expertThe model’s published VoIP data lists SIP support. Match the platform, codecs, registration and required paging or calling workflow, then test the selected configuration before deployment.
The model documentation lists VMS compatibility via ONVIF and an HTTP API for alarm transmission. Agree the required audio action or alarm exchange, and confirm the selected platform, firmware and interface details with SipTok.
The published power-supply field states “PoE/12V-2A”. Check the installation supply and the current model document. For PoE, verify the switch’s per-port and total power budget.
Include the model, quantities, site layout, intended workflow and connected equipment. For a complete system, share paging zones, network and power availability, and any BOQ, RFP or configuration support required.
