Telekom Austria's Serbian subsidiary has become the latest company to trial NFV technology, by virtualising IMS services for residential and business customers.
Vip Mobile has used Metaswitch's open source IMS solution Project Clearwater for the demonstration, offering services such as simultaneous ringing, swift transfers of calls, Wi-Fi to GSM continuity and hosted PBX.
Metaswitch unveiled Project Clearwater last May, promising to offer voice and multimedia services over IP to operators who haven't invested in an IMS core network.
Günther Ottendorfer, CTO,Telekom Austria Group, said: "This is the first time in our Group that an Open Source community project has been used in order to implement telecom services on a virtualised environment in an operator network.
"Telekom Austria Group has already learned many of the advantages possible with virtualisation, following trials in Croatia and Bulgaria. With Vip mobile’s trial we are also starting to understand what advantages Open Source projects will bring to the Group."
He added: "We are absolutely confident that the NFV technology is a paradigm shift for the telecommunication industry and for the Telekom Austria Group this technology evolution is of great importance. We are very proud that Vip mobile achieved another remarkable milestone in our NFV journey."
The group has steadily been conducting a range of NFV trials through its subsidiary companies during the past year. In June, Mobitel streamed content through a virtualised packet core over LTE. Croatia subsidiary Vipnet also demonstrated HD video streaming by using NFV.
