A1 Telekom Austria has claimed to be the first operator in the European Union (EU) to have migrated its entire fixed line voice service to a voice-over-internet protocol (VoIP) platform. According to Total Telecom, the four-year project saw the telco integrate 1,480 switching centres and 2.3 million wireline customers with its all-IP network. The migration was carried out gradually, from west to east, at a rate of 50 switching centres per week. To facilitate the migration, Telekom deployed Huawei’s multi service access node (MSAN) and an advanced IP soft-switch (AIPS) provided by Kapsch CarrierCom on its IP network. CTO Gunther Ottendorfer commented: ‘The integration of fixed net telephony into our all-IP data network was one of the most comprehensive and complex projects in the history of our company.’
