In my experience it is a valid number managed by an Interpreting Co based in Australia/Melb, but for an inexplicable freason some IPS refuse to accept the call connection

i called back and it says it is not allowed

Block this number ... it's a shonky

I called back number (03) 8595 9868 reached voice mail but did not say for what comapny

i have received two phone calls from this number and when i called back it says call to this number is not allowed.

Who is the company that uses this number?
return Call not allowed

have successfully called this number in the past, now I get "number not allowed" message - I found another way to contact the company and they claim the number is still valid?

i called back number (03) 8595 9868 it says calls to this number is not allowed.
