PT101-CB Autodial Outdoor Phone

The Project Telecom PT101-CB Autodial Outdoor Phone is a rugged weatherproof communications telephone developed for industrial and public environments where fast, dependable voice communication is required.

Designed with simple lift-to-call functionality, the PT101-CB automatically dials a pre-configured contact when the handset is lifted, providing immediate access to assistance without the need for manual dialling. Available with Analogue, SIP or GSM / 4G connectivity, the telephone can be deployed across traditional telephony systems, modern IP networks or mobile communications infrastructure, offering a versatile solution for a wide range of applications.

Constructed from corrosion-resistant die-cast aluminium and featuring a protective weatherproof front door, vandal-resistant design and IP66-rated environmental protection, the PT101-CB is engineered to deliver reliable operation in demanding outdoor and industrial locations. Available in Yellow, Blue, Red and Grey finishes, the telephone can be selected to meet site visibility requirements, safety schemes or aesthetic preferences.

Suitable for factories, warehouses, manufacturing plants, transport facilities, utility sites, ports, tunnels, marine environments, security locations, construction projects and public help points, the PT101-CB combines robust construction with flexible connectivity options to support critical communications across a broad range of sectors.

Engineered for Challenging Environments

The PT101-CB has been developed for installation in locations where communications equipment may be exposed to harsh weather conditions, dust, moisture, vandalism or physical impacts. Its heavy-duty die-cast aluminium enclosure provides long-term durability and excellent resistance to corrosion and environmental exposure.

An IP66-rated enclosure helps protect against dust ingress and water penetration, while the weatherproof front door offers additional protection from rain and contamination. This makes the telephone particularly suitable for exposed outdoor installations and industrial applications.

Whether installed within manufacturing facilities, railway infrastructure, ports, utility compounds, tunnels, transport networks or public-access areas, the PT101-CB is designed to maintain reliable communications where operational performance is critical.

The vandal-resistant construction, armoured handset cord and industrial-grade components make it especially suitable for remote sites, public-facing locations and critical infrastructure where equipment reliability is essential.

Simple Autodial Functionality

Designed for straightforward operation, the PT101-CB automatically places a call to a programmed destination as soon as the handset is lifted. This eliminates the need for keypads or manual dialling and ensures users can quickly contact security personnel, control rooms, emergency services or site management teams.

The simple lift-to-call design helps improve usability while reducing response times in emergency and assistance applications.

An integrated inductive coupler is included as standard for hearing aid compatibility, while the high-output warble ringer helps ensure incoming calls remain audible in noisy industrial environments.

Designed for Long-Term Dependability

Built for continuous operation, the PT101-CB combines a corrosion-resistant aluminium housing, weatherproof protective door and stainless-steel armoured handset cord to withstand years of use in demanding environments.

With an MTBF exceeding 50,000 hours, the telephone is engineered to maximise uptime whilst reducing maintenance requirements and operational costs.

The magnetic hook switch design incorporates no visible moving parts, helping to minimise wear and further improve long-term reliability.

Flexible Connectivity Solutions

The PT101-CB is available with three connectivity options, enabling integration into almost any communications infrastructure.

Analogue Version

The analogue model connects directly to standard analogue telephone lines and is compatible with both PSTN and analogue PABX systems. Powered directly from the telephone line, it provides a simple and reliable communications solution for sites utilising conventional telephony infrastructure.

The analogue version supports DTMF remote programming, lift-to-call autodial operation and incoming call functionality.

SIP Version

The SIP version integrates directly with SIP telephone systems, hosted VoIP services and IP-PBX platforms using standard Ethernet connectivity. Supporting SIP 2.0, dual SIP server registration, Power over Ethernet (PoE) and browser-based configuration, it provides a scalable solution for modern IP communications networks.

Support for G.711A/u, G.722, G.723.1, G.726 and G.729 codecs, together with echo cancellation, VLAN, DHCP, PPPoE and STUN functionality, ensures reliable enterprise-grade voice performance.

GSM / 4G Mobile Network Version

The GSM / 4G model operates over mobile telephone networks using a Micro SIM card, providing communications capability in locations where fixed telephone lines or IP infrastructure are unavailable.

Supporting GSM, WCDMA and LTE frequency bands, the telephone can be configured remotely via SMS messaging and includes remote status reporting capabilities for simplified management and maintenance.

This version is particularly well suited to remote sites, temporary installations, utility infrastructure and construction projects.

Available in Four Colours

The PT101-CB is supplied in Yellow, Blue, Red and Grey finishes, allowing the telephone to be selected to suit installation requirements, visibility considerations and site-specific preferences.
