He added that this functionality was proving to be the most attractive to potential customers. "We thought when we started that this would be all about roaming but the feedback we have received from operators we have been talking to is that we were the only people talking to them about growth rather than cutting costs
"That is were the large opportunities are. Mobile operators are looking for new ways of delivering services, to move beyond talk and text, and they are all aware of the over the top operators moving in on their space.
"For example, there is a gaming company that is looking to set up shop in Asia and the mobile operators are very excited but it is hard for them to justify the multimillion dollar investment in infrastructure. However, if the gaming provider knows he can address multiple operators through a single infrastructure, that is much more attractive."
Bell said that Telstra and its Hong Kong mobile subsidiary, CSL, were presently gearing up to use the IPX to support international roaming for LTE services and "There are a couple of others that are keen to work with us but that we can't announce yet."
He said the IPX had been largely developed by Telstra Global in-house by combining its existing GRX - inherited when the former Reach joint venture with PCCW was absorbed into Telstra - with its class of-service-enabled MPLS network. "The [supplier of] the mobility management piece we can't disclose but the rest of the infrastructure has been developed within Telstra Global, leveraging the development we did around GRX and also the class of service capability of our core network."
