CrewPTT

Enhancing In-Store Collaboration with a DECT Push-to-Talk Solution

Delivering exceptional customer service and operational efficiency in today’s fast‑paced retail environment demands seamless, real‑time communication. Our DECT CrewPTT solution—comprising rugged handsets, headsets, intuitive software, and expert integration—empowers store teams to connect instantly, work smarter, and enhance safety, all while driving substantial cost savings.

Streamlined Operations and Cost Savings

By enabling associates to communicate hands‑free across the entire sales floor, our CrewPTT system significantly reduces unnecessary foot traffic. Eliminating walking distances/time per colleague each day translates to huge annual savings per store—funds that can be reinvested in customer experience initiatives or staff development. Whether conducting stock checks, responding to self‑checkout alerts, or coordinating price checks, teams stay focused on high‑value tasks rather than logistics.

Accelerated Customer Response

Equipped with one versatile device, staff can talk, listen, and act from anywhere in the store. Voice alerts for low stock, system notifications, or colleague requests are delivered instantly through the headset, empowering associates to assist customers three times faster. From handling till enquiries to advising on product availability, teams maintain a continuous flow of information, ensuring shoppers enjoy prompt, knowledgeable service.

Unified Device for Communication and Training

Our DECT handset/headset is more than a walkie‑talkie—it’s a multi‑functional tool designed for retail. In addition to CrewPTT calls, associates can receive real‑time voice prompts for stock replenishment, price overrides, or safety alerts. New hires benefit from on‑the‑job coaching: trainers can guide remotely, providing step‑by‑step instructions without leaving the sales floor. This “learn‑as‑you‑serve” approach accelerates ramp‑up times and maintains service standards.

Enhanced Security and Team Safety

Integrating seamlessly with existing security systems (AML), the CrewPTT solution delivers immediate, discreet alerts when incidents occur. Rapid coordination reduces theft incidents, while associates report feeling safer—knowing backup is just a button press away. Whether facing a shoplifting event or managing an emergency, store teams can mobilize swiftly, keeping both customers and colleagues secure.

Conclusion

Our DECT CrewPTT solution transforms in‑store communication—driving efficiency, boosting customer satisfaction, and fortifying security. By uniting hardware, software, and integration expertise, we enable retailers to operate leaner, serve customers faster, and create a safer shopping environment. Empower your team with instant, reliable voice connectivity and experience the future of retail collaboration today.

Resources

CrewPTT groups require resources on the base station.

We have created a tool that can be used to calculate the required resources. 


Base stations under the same DECT manager can handle maximum 2 CrewPTT groups.

A Base station must be selected that acts as the conference bridge for a CrewPTT group.

Enabling CrewPTT or using a Base station as conference bridge takes resources, therefore the tool to calculate the free call capacity.
