Hi, we use a card terminal on our phone line and recently it has been unable to update over the phone line. I contacted the terminal support people and they said there is "not enough line voltage in the phone line" and to ask BT to increase it. Does this make any sense at all, is it something that can be increased, and would there be a charge for that?
I attempted to use the business chat facility but the form does not seem to submit. Nothing happens when I click the submit button.
