What is 'Direct Inward Dialing' (DID) in Avaya systems?

Direct Inward Dialing (DID) is a telecommunications service feature that enables external callers to reach a specific internal extension without going through a receptionist or an automated attendant. This functionality allows organizations to provide direct contact numbers for their employees, enhancing the efficiency of communication. In Avaya systems, DID streamlines the call process, facilitating easier and quicker connections for external parties wishing to contact someone within the organization.

By using DID, businesses can assign unique telephone numbers to individual extensions or departments, which can improve customer service and accessibility. This is particularly beneficial for companies that handle a high volume of calls, as it reduces wait times and simplifies the direct connection between callers and the intended recipient.
