My DID number dont work if i call from a mobile or local number

My did number dont work when i call from my mobile or my local number say cant complete the call

Sorry to hear about this and we see many calls in call history ( my account > call history )

Can we make sure the forwarding is OK, we see at least one calls showing up as “busy”

If there is a specific phone in Brazil that cant reach the flynumber, please let us know the phone number, carrier name and GMT time of the failed call

Thanks and here if you need anything
