User Portion Format Conditions for Directory URI on Cisco Unified Communications Manager 9.1 or Later

AB.

Cisco Unified Communications Manager supports the following formats in the user portion of a directory URI (the portion before the @ symbol): -> Accepted characters are a-z, A-Z, 0-9, !, $, %, &, *, _, +, ~, -, =, \, ?, \, , ,, ., /

-> The user portion has a maximum length of 47 characters.

-> The user portion accepts percent encoding from %2[0-9A-F] through %7[0-9A-F]

For some accepted characters, Unified CM automatically applies percent encoding.

See below for more information on percent encoding.

-> The user portion is case-sensitive or case-insensitive depending on the value of the URI Lookup Policy enterprise parameter.

The default value is case- sensitive.

The Directory URI is a unique identifier used for directory access in Cisco Unified Communications Manager (CUCM). It is used for internal directory searches, corporate directories, and address book synchronization with external applications. In CUCM 9.1 and later versions, there are two user portion format conditions that are true for Directory URI:

A. It supports the $ character: The $ character is a valid character in the user portion of the Directory URI in CUCM 9.1 and later versions. The $ character is used to represent the end of the user portion and the start of the domain portion. For example, a Directory URI for the user "john" in the domain "example.com" would be represented as john@example.com.

D. It has a maximum length of 254 characters: The user portion of the Directory URI has a maximum length of 254 characters in CUCM 9.1 and later versions. This includes all characters, including letters, numbers, and special characters. If a user portion exceeds this limit, CUCM will not be able to process the Directory URI.

B. It does not support space between characters: The user portion of the Directory URI does not support spaces between characters. If a space is required in the user portion, it should be replaced with a special character, such as an underscore or hyphen.

C. It has a maximum length of 50 characters: This statement is incorrect. As mentioned earlier, the maximum length of the user portion of the Directory URI is 254 characters, not 50 characters.

E. It is not always case-sensitive: The user portion of the Directory URI is not case-sensitive in CUCM 9.1 and later versions. This means that "John@example.com" and "john@example.com" are considered the same Directory URI.

F. It cannot be a directory number: This statement is also incorrect. A Directory URI can be a directory number in CUCM 9.1 and later versions. However, it is important to note that a Directory URI that represents a directory number must be unique and cannot be shared with any other Directory URI.
