To use a Limephone as a business switchboard, you would first need to create a call routing plan. This plan would specify which calls should be routed to which department or employee. Once you have created your call routing plan, you can then assign your virtual number to that plan. When a customer calls your virtual number, they will hear a greeting and then be prompted to choose an option. The customer can then press the corresponding key to be routed to the appropriate department or employee. For example, your call routing plan might look like this: Press 1 for customer service. Press 2 for sales. Press 3 for technical support. If a customer presses 1, they will be routed to the customer service team. If they press 2, they will be routed to the sales team. And if they press 3, they will be routed to the technical support team.
