How do you dial 13 XX XX (1300 xxx xxx work)

[n1k88]

We are on NBN Superfast with home phone, but are unable to dial any 13 XX XX numbers. We have tried a few of them over the months but none work. Is there a way to do this?
1300 XXX XXX are fine and work

Hi @n1k88

Thanks for raising this with us.

Is there a certain number that you are not able to reach?

Please send me a PM with the numbers for us to check it further.
