Calls from and to other countries

Calls from and to other countries

Making and receiving international calls.

Multinational companies need easy global calling options. Optus can make it as simple as a local call for international customers to reach your Australian office and we help smooth the path for your team to make calls when they are working overseas.

The right connections for great global customer experience

Give your overseas customers and staff a convenient way to reach you. International Inbound Voice Services allow callers to phone your organisation free of charge* from fixed lines in many of the world's major business centres - either a single contact number, or a number specific to the caller's country.

*Some hotels and public phones may charge a local call fee.
