Voice calling over business broadband

VDSL business broadband optimises your business calling with voice calling over broadband (VoIP) instead of calls over an old copper line, at no additional cost

A man smile as he makes a phone call.

What is voice calling over broadband?

Voice calling over broadband has been available to fibre customers for some time but now we’re adding the latest in calling technology to VDSL broadband. It offers the same features and services as you’ve been used to over a copper landline but is future-proofed as new features and functionality become available.

Heads up!

If you want to use a fax machine, PABX or EFTPOS terminal over your calling connection, we recommend you check with your service manufacturer as we cannot guarantee that they will work. If the answer from your service provider is no, you should consider whether stay with a phone service provided over a standard copper cable connection.
