Number of Directory URIs Associated with a Cisco Unified Communications Manager Directory Number

E.

Cisco Unified Communications Manager supports dialing using directory URIs for call addressing.

Directory URIs look like email addresses and follow the username@host format where the host portion is an IPv4 address or a fully qualified domain name.

A directory URI is a uniform resource identifier, a string of characters that can be used to identify a directory number.

If that directory number is assigned to a phone, Cisco Unified Communications Manager can route calls to that phone using the directory URI.

URI dialing is available for SIP and SCCP endpoints that support directory URIs.

In Cisco Unified Communications Manager (CUCM), a directory number (DN) is a unique identifier assigned to a line or device, allowing for calls to be routed to that line or device. A directory URI is a Uniform Resource Identifier that can be associated with a directory number to enable the user to access various types of directories, such as corporate or personal directories.

The answer to this question is A. 1. A directory number in CUCM can only be associated with a single directory URI. This means that each DN can only have one directory URI associated with it, and this URI must be unique.

It's worth noting that CUCM does support multiple directory URIs, but they are associated with different DNs. In other words, each DN can only have one associated directory URI, but multiple DNs can be associated with different directory URIs.

Therefore, if a user wants to access multiple directories, they will need to have multiple directory numbers, each associated with a unique directory URI. The user can then switch between directories by selecting the appropriate directory number.

In conclusion, the number of directory URIs with which a Cisco Unified Communications Manager directory number can be associated is one (A).
