Business phone: hosted voice vs landline

Most businesses move to hosted voice for features and end up keeping it for the flexibility.

What hosted voice changes day to day

Calls route over your internet connection rather than a copper line, which means extensions can live anywhere, call flows can change without an engineer visit, and voicemail, auto-attendants, call recording and reporting come as configuration rather than hardware. For multi-site businesses, one numbering plan can cover every location.

Your connection becomes part of the phone system

Because voice runs on the same circuit as everything else, call quality depends on capacity and prioritisation. Voice traffic should be prioritised at the router, sized for concurrent calls, and ideally protected by a failover path so a line fault does not take the phones with it.

Questions to ask before you switch

  • Can every published number be ported, including fax and tracking numbers?
  • What happens to calls during an internet outage — do they divert to mobiles automatically?
  • Are emergency calling details registered correctly for each physical site?
  • How many concurrent calls does the plan support at peak?
  • Which handsets are supported, and who configures them?
  • What are the contract term and exit notice?

Port early, keep the old lines running

Number porting runs on its own schedule and is the most common cause of a rough cutover. Start it as soon as service is ordered and never cancel the old carrier before the port completes — cancelling can release the number.

Frequently asked questions

Will I keep my business phone number?+

Yes in almost all cases. Numbers are ported to the new service; the key is starting the port early and keeping the existing lines active until it completes.

What happens to phones if the internet goes down?+

Hosted platforms can divert calls to mobiles or another site automatically. Configure that before go-live rather than during an outage, and consider a backup connection for sites where calls are revenue.

Can phone and internet come from one agreement?+

Yes. Quoting them together means one account team, one install schedule and one contact when something needs attention.
