FAQ

Frequently Asked Questions

Will VoIP still work if our internet goes down?
If your primary internet connection fails, calls will too — just like any internet-dependent service. We mitigate this by configuring failover to a secondary connection or mobile data backup, and by enabling softphone apps on staff mobiles so they can still make and receive calls on the business number.
How does VoIP call quality compare to a traditional landline?
On a well-configured network with adequate bandwidth, VoIP call quality is indistinguishable from — or better than — a traditional landline. Poor quality is almost always a network issue, not a VoIP issue. We assess your network before any installation to ensure it’s ready.
How much could we save by switching to VoIP?
Most businesses moving from ISDN or hosted PBX reduce their monthly telephony costs by 40–60%. Call costs are significantly lower, line rental is eliminated, and adding extensions doesn’t require expensive hardware. We can model a comparison against your current bill.
How disruptive is the switch to VoIP?
Minimal, when planned properly. We provision and test all hardware before installation day. Number porting is planned with you to coincide with go-live and keep disruption to a minimum, and you keep your existing numbers. Most businesses are fully operational on the new system within a single working day.
What happens to voicemail and call recordings when someone leaves the business?
User accounts, voicemail boxes, and call recordings are managed centrally through the admin portal. When a staff member leaves, we reassign their extension as needed. Call recordings and voicemail are kept for 90 days by default and then deleted automatically, so download any recording you need to keep for longer.
What about 999 calls and power cuts?
Internet phone service needs mains power and a working internet connection, so in a power cut, or if your broadband or equipment fails, your phones may not work — including for 999 and 112 calls. Keep a charged mobile phone to hand. If anyone relies on your phone line to call 999, for example because of a health condition, a telecare alarm or no mobile signal, we provide a battery backup unit free of charge — just ask us on 0333 340 7067. Please keep each site’s address up to date with us, so 999 calls give the emergency services the right location.
