Internode customers can now migrate their telephone number to NodePhone, Internode's VoIP service.

Switching to VoIP means broadband customers can make cheaper calls over the internet and even cancel their landline service altogether, saving monthly line rental costs.

Internode product manager Phil Dempster said: "Being able to keep their existing phone number overcomes a barrier to people adopting Naked ADSL2+.

"We also think it will appeal to NBN customers who are so happy with their fibre-based broadband service that they decide to get rid of the monthly cost of renting a separate telephone line.

"Another benefit for customers with a ported number is that when moving house, they can now take their telephone number, delivered by an Internode broadband service, to anywhere in their metropolitan area."

Initially, the porting service will only be available for customers in the Adelaide, Brisbane, Canberra, Hobart, Melbourne, Perth and Sydney metropolitan areas.

Customers will only be able to port a number if they are a Telstra customer, but Internode is hoping to extend the service to other providers at a later date.

The number-porting process costs $29.95 and customers will need a VoIP enabled modem compatible with Internode's NodePhone service, the company said.

Internode has several good value Naked broadband deals, including its Home Naked DSL Extreme plan with 100GB of data to be used anytime for $89.95 a month on a 24-month contract.

NodePhone VoIP effectively turns the whole of Australia into a local call zone, so it is perfect for making interstate calls. NodePhone plans start from just $5 a month and this includes $10 of credit.
