With the UK Switch Off approaching, many organisations still rely on analogue equipment that works perfectly well. Replacing everything at once is rarely practical. Budgets are tight, and any change risks disruption. That is where Analogue Telephone Adaptors, or ATAs, come in.
What is an ATA?
An ATA is a small device that converts analogue voice from your existing phones, handsets, intercoms, fax machines or lift lines into digital VoIP. It lets you keep trusted analogue hardware, while connecting to modern SIP services over your data network.
Why this matters:
- Minimise costs. Keep working devices and upgrade at your pace.
- Reduce disruption. No need to rewire or retrain overnight.
- Move to VoIP quickly. Gain IP features and resilience now, even if a full system refresh is planned later.
- Support special lines. Ideal for sites with legacy endpoints, including reception phones and critical services.
Industry estimates suggest around 33% of businesses still use ISDN as their underlying communications. ATAs offer a fast, low-risk route to keep services live and compliant while you plan the long-term move.
When to choose an ATA
- You need to retain analogue devices during the Switch Off.
- Budget or cabling constraints make a full rip-and-replace unrealistic right now.
- You want to phase your migration, keeping service continuity.
- You have special lines like lifts, door entry, or fax that need a reliable bridge to IP.
