No BT landline available at our new business premises so purchased a landline telephone number from SwitchboardFREE (which I selected from loads of options) and configured the switchboard options for the different company departments, which divert to different company mobile phones, in under 30 mins. Also configured the landline number to align with our business opening hours so callers receive a message advising them that the business is closed and to call back. What an excellent product! Any missed calls are visible in the app and you have the option to record calls.
