The Challenge
As telecom carriers accelerate the decommissioning of POTS lines, businesses face a critical loss of control over their essential communication infrastructure. Relying on an expiring technology means surrendering control of service reliability, feature availability, and pricing to providers who are incentivised to push for costly, often inconvenient, alternatives. This lack of control jeopardises operational stability and strategic planning.
Business Impact
Loss of Operational Autonomy
Without a proactive POTS replacement strategy, businesses are left reactive to carrier schedules and price increases. This undermines the ability to plan communication infrastructure upgrades, negotiate fair terms, and ensure consistency in service delivery. Key operational functions tied to POTS, such as alarm systems, fax lines, or emergency phones, become vulnerable to external forces.
Fragmented Communication Management
Migrating away from POTS without a unified strategy can lead to a patchwork of communication tools, making central management impossible. This fragmentation complicates user provisioning, policy enforcement, and troubleshooting, eroding overall control over the business communication environment.
How Tango Extend Solves This
Tango Extend puts control firmly back in the hands of the business. By integrating business mobile communications directly into a centralised UC platform like Microsoft Teams or Webex Calling, it provides a single pane of glass for managing all voice, messaging, and call handling features that previously relied on POTS. This ensures consistent policies, simplified administration, and complete oversight.
- Centralised Administration — Manage all mobile business lines, users, and features from your existing UC platform, eliminating disparate systems.
- Policy Enforcement — Apply granular communication policies, such as recording, routing, and access, uniformly across all devices, including BYOD.
- Direct Number Management — Maintain ownership and control over business phone numbers, porting them seamlessly to the mobile-first solution.
- Service Consistency — Ensure a consistent user experience and service quality across all communication methods, enhancing overall control and reliability.
Use Case
A financial advisory firm relied on POTS lines for internal office phones and dedicated fax services, which were subject to strict regulatory requirements. As their carrier announced POTS sunset dates, the firm worried about losing control over phone numbers and ensuring secure, auditable communication. They implemented Tango Extend, porting their critical numbers to the mobile-first platform, which integrated directly with their Microsoft Teams setup. This allowed their IT team to centrally manage all mobile business lines, apply call recording policies automatically, and maintain full oversight of communications and compliance, completely removing their dependence on external POTS providers and regaining full control over their communications.
FAQs
Q? Will I lose my existing business phone numbers if I replace POTS?

Q? Can I still manage communication policies like call routing and recording with a mobile-first solution?
A. Absolutely. Tango Extend integrates with your UC platform, enabling you to apply and manage all communication policies, including call routing, voicemail, and mandatory call recording, from a central administrative console.
