Project Telecom PT104-SC SIP Push-to-Call Outdoor Phone - Blue

The Project Telecom PT104-SC SIP Push-to-Call Outdoor Phone is a professional-grade IP communications solution designed to deliver reliable handsfree voice communications in harsh industrial, outdoor and public-access environments. Featuring simple push-to-call functionality, open access weatherproof design, full duplex SIP communications, Power over Ethernet (PoE) connectivity, IP66 weatherproof protection and vandal-resistant construction, the PT104-SC provides dependable operation where conventional telephones may be unsuitable.

Designed for factories, warehouses, manufacturing facilities, transport infrastructure, rail networks, utility sites, ports, docks, marine environments, tunnels, construction projects, airports, car parks and public assistance points, the PT104-SC allows users to connect instantly with a pre-programmed destination at the press of a button. Its corrosion-resistant die-cast aluminium housing protects internal components from dust, moisture, impact and harsh weather conditions, ensuring reliable communications in demanding environments.

Heavy-Duty Construction for Harsh Environments

Engineered specifically for industrial and public-access applications, the PT104-SC features a robust die-cast aluminium enclosure and industrial epoxy powder-coated finish. This heavy-duty construction provides excellent resistance to corrosion, weather exposure, impacts and vandalism while helping protect internal electronics from environmental damage.

Tamper-resistant fixings and vandal-resistant components further enhance security, making the PT104-SC ideal for exposed locations where dependable communications are essential. Designed for long-term deployment, the telephone delivers reliable performance in industrial facilities, transport infrastructure, utility sites, marine environments and other demanding applications.

Simple Push-to-Call Operation

The PT104-SC SIP version provides straightforward operation through a vandal-resistant single stainless-steel call button. Users simply press the button to automatically connect to a pre-programmed SIP destination without requiring manual dialling.

This simple user interface makes the telephone particularly suitable for emergency assistance points, customer help stations, security applications, access control systems and industrial communications networks where immediate access to support services is required. Non-volatile memory ensures programmed settings are retained during power interruptions, helping maintain operational reliability.

SIP Connectivity with PoE

The PT104-SC SIP version integrates directly with modern IP telephony infrastructures using standard SIP protocols. Supporting SIP 2.0 (RFC3261), the telephone can connect to IP-PBX systems, hosted VoIP platforms and SIP-based communications networks.

Power over Ethernet (PoE) support simplifies installation by delivering both power and network connectivity through a single Ethernet cable. A 12V DC power option is also available where PoE infrastructure is not present. The integrated web-based configuration interface and telephone management software allow straightforward deployment, remote programming and ongoing system administration.

High Quality Full Duplex Voice Communication

Designed as a handsfree communication device, the PT104-SC delivers high-quality full duplex audio, allowing natural two-way conversations without interruption. Advanced echo cancellation technology supports clear speech transmission in challenging acoustic environments while reducing background interference.

Support for multiple voice codecs including G.711, G.722, G.723.1, G.726 and G.729 enables compatibility with a wide range of VoIP systems while optimising audio quality and network efficiency.

IP66 Weatherproof Protection

The PT104-SC features an open access weatherproof design engineered to provide IP66-rated protection against dust ingress, moisture and water exposure. IP67 protection is available on request for applications requiring enhanced environmental resilience.

Designed for continuous outdoor deployment, the enclosure protects critical electronics from harsh environmental conditions while maintaining reliable communications throughout the year in exposed industrial, transport and public-access locations.

Accessibility & User Safety Features

For applications requiring hearing aid compatibility, an optional inductive coupler can be supplied on request. This feature helps improve accessibility for users with hearing impairments while maintaining simple handsfree operation.
