Caller-ID Routing is an important business feature allowing you to distinguish important clients with expedited service. It let those clients skip the auto-attendant and queues and connects directly to an appropriate agent.
When activated, the system scans a list of numbers, comparing it the caller ID of an incoming calls. If there is a match, the call is immediately routed to a destination associated with the number - a department, an extension, a queue, a voicemail, or even an agent's mobile phone.
This is a great time saver for your VIP clients who receive fast instant access to the agent or department who are most suitable to assist them. Those clients, while possible having a list of relevant direct numbers in your company, will really appreciate needing to only dial your company's main number.
