Wondering if anyone can help, I have a samsung phone with optus and all of a sudden I can't call telstra numbers it just says line busy. But I can call optus numbers. Thanks

What's going on?
It hasn't gotten any better all day!
This is ridiculous.
Is there an ETA on this fault being repaired?

I got through to Optus after waiting for an hr. Apparently it’s a Telstra issue. It’s only dialling out to Telstra numbers is an issue. You can call other Optus mobiles. To get around it I’ve whatsapp’d call people

You sound well ahead of it all Irene. 😀 Hopefully the new day will have this problem resolved.
