Directory URI

A SIP URI such as user@example.com assigned to a CUCM user or DN so callers can dial by alphanumeric address.

Definition

Directory URIs can be populated from the user's mail ID or configured manually on the DN. They are placed in a partition associated with the DN and can be advertised to other clusters with ILS and GDPR. Video endpoints and soft clients use them for B2B and intercluster calling.

Example

Alice's DN 1001 has directory URI alice@example.com, so a room system can dial her by URI.

Exam tip

Directory URIs are routed separately from numbers; they need partitions and CSS access like DNs.
