What is telephone number mapping in 3CX?

Telephone number mapping in 3CX refers to the process of associating specific phone numbers with extensions or users within the system. This allows incoming calls to be directed to the appropriate user or extension based on the dialed number. By establishing this mapping, businesses can ensure that calls are efficiently routed, enhancing communication and response times.

This feature is particularly useful for organizations that have multiple phone numbers for different departments or services, enabling seamless handling of calls. In this context, knowing which number maps to which user is vital for effective call management and customer service. This capability streamlines operations and improves overall user experience, as it ensures that calls reach the intended recipients without unnecessary delays or confusion.

The other options, while related to call management, do not accurately define telephone number mapping. Routing calls to voicemail or blocking unwanted calls pertains more to call handling features, while creating an internal directory of contacts is about organizing user information rather than mapping numbers to extensions.
