The Challenge
Organisations grappling with the impending obsolescence of traditional Plain Old Telephone Service (POTS) lines face a critical imperative: find a modern, reliable, and sustainable alternative. The copper lines supporting POTS are old, increasingly prone to failure, and expensive to maintain. Carriers are actively decommissioning these services, leaving businesses reliant on them vulnerable to service disruption and rising costs.
Business Impact
Operational Risk
Continued reliance on POTS lines introduces significant operational risk. Service outages can lead to lost business, missed opportunities, and damaged customer perception. Maintenance calls are becoming more difficult to schedule and often require specialised, dwindling expertise, resulting in prolonged downtime. Business continuity is severely compromised when critical communication infrastructure is at the whim of aged technology.
Escalating Costs
As POTS infrastructure ages and becomes scarcer, the costs associated with its maintenance and minimal service guarantees are spiralling upwards. Businesses are paying more for less reliable service, creating an unsustainable financial burden. Migrating proactively avoids emergency, high-cost solutions later.
How Tango Extend Solves This
Tango Extend offers a robust, mobile-first POTS replacement solution that fully integrates into unified communications platforms like Microsoft Teams and Cisco Webex Calling. This eliminates the need for physical copper lines by leveraging enterprise-grade mobile connectivity, ensuring your business stays connected and compliant wherever your employees are.
- Seamless Integration — Replaces POTS lines by bringing business voice and features directly onto employee mobile devices, integrated with your UC platform.
- Guaranteed Reliability — Leverages resilient mobile networks, significantly reducing uptime concerns associated with aging POTS infrastructure.

- Cost Optimisation — Eliminates high POTS line charges and reduces capital expenditure on legacy equipment, leading to significant cost savings.
Use Case
A manufacturing plant relied on several POTS lines for factory floor communications, emergency services, and legacy alarm systems. Facing mandated decommissioning, they deployed Tango Extend. Their existing desk phones were replaced with mobile devices equipped with the Tango Extend app, integrated into Microsoft Teams. This ensured all factory personnel had secure, reliable mobile communication, including direct lines for critical alerts, without needing new cabling or complex infrastructure upgrades. Emergency services contact remained uninterrupted, and the entire system was future-proofed against further POTS sunsets.
