In North America (USA, Canada, etc.), dial *67 or equivalently 1167 to block sending your Caller ID on a per-call basis. Other countries use different codes for this purpose.

Will 67 work when dialing out on a fax line?

In the US and Canada, dialing *67 on any landline will suppress the Caller ID display at the far end. (Note that calls to toll-free numbers and to 911 will still display your number, even if you block Caller ID.) A fax line is nothing but an ordinary landline that happens to have a fax machine connected to it. You can swap a fax machine and an ordinary telephone on the same line.

How do you block call waiting calls on landline phone?

To block call waiting on a landline phone, you typically need to activate a specific feature through your phone service provider. You can do this by dialing a code, such as *70 in the U.S., before making a call, which temporarily disables call waiting for that call. Alternatively, you can contact your service provider to permanently disable the call waiting feature on your line. Always check your provider’s documentation for the exact steps, as they can vary.
