Deutsche Telekom’s Croatian fixed line and mobile subsidiary T-Hrvatski Telekom (T-HT) has completed its migration to all-IP technology. The firm says it spent HRK400 million (USD59 million) on the five-year upgrade project, which involved the closure of 72 legacy exchanges and the construction of two new exchanges in Rijeka and Zagreb. T-HT says the switch to all-IP technology will enable it to provide better quality services for its customers and allow it to introduce more advanced converged services in future.
According to TeleGeography’s GlobalComms Database, T-HT began to actively migrate fixed line voice consumers to IP technology in 2010, whereas previously it had preferred to aim IP voice services at corporate clients. By December 2011 T-HT had migrated 67,000 customers to VoIP packages, and by the end of 2012 it said that its IP voice base reached 288,000, growing to 492,000 another twelve months later and 614,000 at end-2014. With a continuing loss of traditional PSTN lines, however, its total fixed telephony subscriber base fell during 2014, from 1.13 million at the start of the year to 1.05 million at 31 December. T-HT’s share of the country’s total fixed telephony retail subscribers stood at around 77% at the end of 2014, down from 79% a year before.
