01
Paging workflow
The operator selects the intended area and the configured platform coordinates the supported announcement workflow.
02
Call workflow
Compatible SIP endpoints establish calls through the configured platform. Define extensions, permissions and call destinations during commissioning.
Connection, power & commissioning notes
- Ethernet branches connect the shown IP devices to the site LAN switch. This is a connection concept, not a cable-routing or electrical wiring drawing.
- SIP handles call setup. RTP audio follows the configured media path; it does not necessarily pass through the SIP server. Multicast is a separate, model-supported paging option.
- Confirm power for each device independently. A PoE switch in this example does not establish the required PoE class, port budget or a universal one-cable installation.
Photographs show actual SipTok models. This is a conceptual connection diagram; cable routes, power and final equipment are confirmed during system design.
