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.
