    The Challenge

    The prospect of replacing critical POTS lines often brings fear of service disruption, downtime, and business paralysis. Many essential systems, from alarm lines and elevator phones to payment terminals and main business numbers, rely on POTS. Ensuring a smooth transition without interrupting these services is paramount, yet complex, given the age and embedded nature of POTS infrastructure.

    Business Impact

    Operational Downtime & Revenue Loss

    Any significant service interruption during a POTS transition can lead to immediate operational downtime. This means lost sales, inability to process customer orders, stalled production, and ultimately, direct revenue loss. The cost of even short outages can be substantial, making a disruption-free migration a top priority.

    Customer Dissatisfaction & Reputation Damage

    Customers expect consistent, reliable service. If your primary contact numbers are down or your operational systems are offline due to a POTS migration, it directly impacts customer satisfaction and can quickly damage your brand's reputation for reliability and professionalism. Managing the transition effectively is crucial for maintaining trust.

    How Tango Extend Solves This

    Tango Extend is designed to facilitate a low-risk, gradual, and non-disruptive POTS replacement. Its approach allows businesses to port numbers and migrate services incrementally, ensuring continuity of service during the transition. By leveraging existing mobile infrastructure and integrating with established UC platforms, it minimises the need for new, complex hardware deployments that often carry risk of disruption.

    • Phased Migration Strategy — Supports a gradual transition, allowing businesses to move services and numbers over time, reducing big-bang cutover risks.
    • Number Porting Expertise — Facilitates seamless migration of existing business phone numbers, ensuring continuity for customers and stakeholders.
    • Leverages Existing Infrastructure — Integrates with your current UC environment and mobile networks, avoiding complex and disruptive new hardware installations.
    • Robust Redundancy — Built on resilient mobile and cloud platforms, providing inherent redundancy and reliability post-migration.

    Use Case

    A hotel chain relied on numerous POTS lines for guest services, front desk operations, fire alarms, and elevator phones. Facing carrier-mandated POTS removal, they feared significant downtime during the transition, especially for critical safety systems. They partnered with Tango Extend for a phased roll-out. Key business numbers were ported first to the mobile-first solution integrated with their Microsoft Teams system, enabling staff to continue receiving calls on their business mobiles without interruption. Safety lines were then migrated with careful testing. The incremental approach, coupled with Tango Extend's reliability, ensured zero business downtime, guest services were unaffected, and emergency systems remained operational throughout the transition, avoiding any service disruption.

    FAQs

    Q? Can I port my existing POTS phone numbers to a mobile-first solution without interruption?

    A. Yes, number porting is a standard process that Tango Extend handles. It allows you to retain your existing geographical or toll-free numbers, ensuring customers can still reach you on the same numbers during and after the transition, with minimal interruption.

    Q? What about critical services like alarm lines or elevator phones that use POTS?

    A. Critical services require careful planning. Tango Extend can often replace the communication aspect of these services by providing a dedicated mobile-connected line or by integrating with modernised versions of these systems. Each case needs to be assessed to ensure adherence to safety and regulatory standards, but Tango Extend offers a pathway to modern replacements.
