Project Telecom PT103-CB SIP Autodial Outdoor Phone - Blue

The Project Telecom PT103-CB SIP Autodial Telephone is a robust weatherproof hotline telephone designed to deliver reliable communications in demanding industrial, outdoor and public-access environments. Featuring lift-to-call operation, an open-access weatherproof design, IP66-rated protection and vandal-resistant construction, the PT103-CB provides a dependable communication solution where standard telephones are unsuitable.

Designed for factories, railways, utilities, transport infrastructure, marine facilities, tunnels, car parks, security installations and public help points, the PT103-CB connects directly to SIP-based telephone systems and VoIP networks. Its rugged die-cast aluminium housing, armoured handset cord and tamper-resistant construction ensure dependable long-term performance in harsh operating conditions.

Heavy-Duty Construction for Demanding Environments

Built for continuous operation in challenging conditions, the PT103-CB features a corrosion-resistant die-cast aluminium enclosure with an industrial epoxy powder-coated finish. This heavy-duty design provides excellent resistance to weather, impact, vandalism and industrial contaminants.

The impact-resistant ABS handset is fitted with a stainless-steel armoured cord for additional durability, while tamper-resistant mounting bars and fixings help protect the telephone in exposed locations. An electric and magnetic hook switch with no visible moving parts further enhances reliability and reduces maintenance requirements.

SIP Connectivity

The PT103-CB SIP Outdoor Phone is designed for deployment on modern IP telephony networks and supports SIP 2.0 protocol compatibility for seamless integration with hosted VoIP services, IP PBX platforms and enterprise communications systems.

Powered via Power over Ethernet (PoE) or an optional DC power supply, the telephone provides straightforward network connectivity through a standard RJ45 Ethernet connection. Advanced network features including DHCP, VLAN, PPPoE and STUN support enable flexible deployment across a wide range of network environments.

Lift-to-Call Hotline Operation

Designed as a dedicated hotline telephone, the PT103-CB automatically initiates a call to a pre-configured destination when the handset is lifted, providing immediate communication without complex dialling procedures.

This simple operation makes the telephone particularly suitable for emergency assistance points, security applications, transport infrastructure, industrial facilities and public help points where fast access to support services is required.

Open-Access Weatherproof Design

Unlike enclosed weatherproof telephones that utilise a protective front door, the PT103-CB features an open-access design housed within a fully weatherproof IP66-rated enclosure. This allows immediate access to the handset without opening a cover, making it particularly suitable for high-traffic public locations and emergency communication points.

Its corrosion-resistant housing provides protection against dust, moisture and harsh weather conditions while maintaining ease of use and accessibility.

HD Voice & Full Duplex Communication

The SIP version supports full duplex voice communication and a wide range of industry-standard codecs including G.711, G.722, G.723.1, G.726 and G.729. Integrated echo cancellation technology helps ensure clear and natural conversations, even in challenging environments.

Support for dual SIP accounts and SIP server redundancy further enhances reliability and deployment flexibility.

Accessibility & User Safety Features

To improve accessibility, the PT103-CB includes an inductive coupler as standard, providing compatibility with hearing aids and assisting users with hearing impairments.

Non-volatile memory retains programmed settings during power interruptions, ensuring reliable operation and reducing maintenance requirements.
