Searching Records

SBC can search the registration name status based on the part of the Address of Record (AOR). It also provides the ability to search the entries which are not in the statistics table but registered in the SBC application using a part of the AOR name or the entire AOR name. The registration ID (RegID) is also used as a search function. In case of unknown registration ID, 0 is specified as a wildcard entry. AOR consists of userPart (user name) and hostname (user name end point IP address), and is expressed in the userPart@hostname format.

SIP Active Register Name Status - Part AOR Search

SIP Active Register Name Status - Entire AOR Search

Wildcard entry is available only for CLI and not for EMA.
