Last week my family made international calls. No problem. On Monday we tried calling overseas, the phone dials, then nothing. No ring tone, no beeping, no busy tone, just nothing.

I talked to Slingshots technical support which after almost an hour came to the conclusion that the number I try dialing is incorrect and the problem does not seem to be on their end as they are able to connect to other international numbers, just not the one I am trying to dial.

The problem here is that I dialed several different numbers of 2 different countries, with the same result. The phone dials, then nothing. And I can see on my call history online that if I listen to the nothingness a little to long, hoping for a ring tone, I get charged for the first minute.

I am able to dial local numbers fine. I am able to call my landline and it works fine. Only international calls do not seem to work as of Monday.

I have tried to explain to Slingshot that I can dial the number, they say does not work, fine via my Vodafone mobile. I have tried to explain that other international numbers do not work also. They have no explanation.

Our home phone is connected to our fibre box. I have tried restarting it, just in case this is the issue. It did not help the issue.

So, I am open to anyone who might have had this problem before or might have any suggestions on what to do next.
