Optus has launched an over-the-top VoIP application for wholesale customers.
The application, ipPhone Express, can be used with traditional telephone handsets, IP phones or with a soft-phone set up on a PC, Optus said.
Optus said it is targeting existing customers in addition to new cloud resellers.
The product will let resellers transfer customers from competitors while allowing them to keep their existing landline phone numbers. The application and can also be bundled with other services and offered over-the-top of any broadband service, Optus said.
"An over-the-top cloud-based voice solution that allows resellers to transfer customers from competitors and keep their 'all important' landline number is a key differentiator for Optus and a very exciting proposition for our wholesale partners," said Optus wholesale and satellite managing director, Robert Parcell.
"As consumer and business confidence in VoIP continues to climb and fixed revenues stagnate, our resellers have been looking for new ways to capitalise on this trend, capture new customers and claim a competitive advantage."
Parcell said he expects interest to grow as build out of the NBN continues. "As [resellers'] customers migrate from traditional copper-based phone lines to an NBN connection, a wealth of opportunity unfolds," he said.
