Korean-based SK Telecom and Hong Kong-CSL have announced a LTE roaming agreement using Telxtra’s IPX interconnect service. But there’s more to come, says a Telstra official.
“Leveraging QOS enabled networks allows Telstra International to control the quality of the voice call from the origin to the destination across markets in Asia, Europe and US,” said Nathan Bell, Global Products and Marketing Director, Telstra International via email. “Hence as part of our roadmap, Telstra International is looking into the HD Voice functionality to be supported by reporting and call flow monitoring.”
Bell’s comment matches BT International’s recent theme of managing end-to-end QoS for voice to aid/enable HD voice calls across carriers.
