The 999 service here apparently gets calls from overseas occasionally.

You can dial it simply by using it as if it were a local number. i.e. international codes followed by a valid area code followed by 999.

I have no idea why it's not barred from abroad.

Although bear in mind that caller ID from any country with a digital phone system cannot be hidden from 999 as it ignores the do not display flag and gives the operator your number. Also, all calls are recorded.

So call from australia and expect to have eircom call telstra ! [Linked Image]
