PSTN switch-off

BT is switching off the PSTN β€” are you ready?

FAQ

Frequently asked questions

Can I keep my existing phone number?

Yes. We port every number β€” geographic, non-geographic and international β€” with a rollback plan and zero downtime.

Will VoIP cope with my broadband?

We assess your circuit, QoS, jitter and packet loss. If your line isn’t fit for VoIP, we’ll quote a leased line, FTTP or SD-WAN that is.

Can I use Microsoft Teams as my phone system?

Absolutely. We provide Teams Direct Routing so your team makes and takes external calls inside the Teams client.

What happens during a power cut?

Calls auto-route to mobile or alternative numbers via our resilient carrier setup β€” your business stays reachable.
