You are not authorized to call this number

It sounds like you're encountering a "call blocked" or "call not permitted" message when trying to dial certain US numbers, even though you've successfully called them before. This can be frustrating, but there are a few things you can try to resolve the issue:

Verify the Dialing Format:

• Double-check that you are using the correct dialing format for the US. Sometimes, small changes (like missing country codes or dialing incorrectly) can cause issues with connecting to numbers. Make sure you are dialing 1 for US numbers followed by the area code and number.

Test with Another Phone:

• If possible, try calling from a different phone or line to see if the issue persists. This will help determine whether the problem is specific to your phone or account.

Reset Your Landline Connection:

• Try disconnecting the phone line from the jack and waiting for a few minutes before plugging it back in. Sometimes a simple reset of the phone line can help resolve these types of issues.

If the above steps don’t work, send us a private message and provide details about the specific numbers you're trying to call. We can get someone to look into this with you.
