Shahid. Calling Australia from Pakistan is not a big deal any more. There are many DID companies now offering incoming calls from Pakistan to Austrlia. The same companies are offering out bound calls from Australia to Pakistan. Vonage works for Australia but not for free. They have free outgoing and incoming VOIP telephone service to USA, Canad, UK, Spain, Italy, Ireland and France but for Australia is not free. You can check up their rates by visiting their website.
