CNAME ENUM Query flow is as follows:
  1. Retrieve the DN from the ENUM query and lookup UDR for required DN.

    If DN is not found in UDR then apply ENUM default action, otherwise proceed with next step.

  2. If ENUM Record is found in UDR for retrieved DN, then check if CNAME record is present in UDR response.

    If no CNAME record is provisioned, then apply default action or proceed with next step.
