How our phone service works
Thamesoptic phone is a fibre VoIP service. It runs over your fibre connection — not a traditional BT copper line — and is included free with every broadband package. Here's exactly what that means for you.
Keep your existing number
We port your current landline number across when you switch — no new number, no double bills.
Fibre VoIP, not a BT line
Your phone connects to your fibre router instead of a copper line. Calls are crystal clear and included free with every package.
Battery backup available
Because VoIP needs power, we offer an optional battery backup for vulnerable customers — recommended if you rely on a landline for medical alarms.
999 calls during a power cut
Your fibre router and battery backup keep you connected during short outages. We will tell you the exact backup runtime at install.
