Where ST-SP20 fits.
A SIP phone can form the operator side of a calling or supported paging workflow. Its call behaviour depends on the configured platform and destination devices.

01
Two-way calling
An operator or intercom user calls the configured SIP extension. Set call routing and answering procedures on the platform.
02
Supported SIP paging
Use this phone’s documented paging function with a compatible platform and announcement endpoint; group behaviour must be configured and verified.
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.
