Transport infrastructure
A direct connection. When every moment matters.
Plan roadside assistance and control-room communication with VoIP emergency call boxes and outdoor IP audio endpoints.
APPLICATIONS & EQUIPMENT
Designed around the way your site works.
THE OPERATING ENVIRONMENT
Highways & Transportation
Long distances between roadside assets and staffed control rooms require careful planning of connectivity, device power and call handling.

Local public information at managed facilities
Operator communication across separated locations
RECOMMENDED ARCHITECTURE
From the control room to the application zones.
Suggested SipTok models are shown in their system roles. The network, operator workflow and final configuration are planned for the application rather than implied by a product list.

01
Announcements
Define paging groups for Control room, Assistance point, Service area. Match the selected speakers and announcement method to each area’s acoustic and operational needs.
02
Assistance & response
Route the suggested call box or intercom to an attended operator through a compatible SIP platform. Define answering and escalation procedures separately from speaker paging.
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.
- Confirm roadside enclosure requirements, surge protection, backup power and network reach for each location. Solar operation is not assumed.
Photographs show actual SipTok models. This is a conceptual connection diagram; cable routes, power and final equipment are confirmed during system design.

IP audio fundamentals
What is an IP-based public address system?
An IP PA system carries announcement audio over an Internet Protocol network. Instead of taking every speaker back to a central audio amplifier, network endpoints receive digital audio and reproduce it locally.
Read the guideSIP & VoIPHow SIP speakers work in a paging system
A SIP speaker combines a network audio endpoint with a loudspeaker and amplifier. SIP establishes the communication session; a media protocol such as RTP carries the audio.
Read the guideNetwork designSIP paging vs multicast paging
SIP paging and multicast paging solve different parts of audio distribution. SIP can establish a call to an endpoint or platform group, while multicast can distribute a stream to multiple listeners on a managed network.
