Cisco Unified Communications Manager Administration, use the submenus under the menu path to configure call control discovery.
The call control discovery feature leverages the Service Advertisement Framework (SAF) network service, a proprietary Cisco service, to facilitate dynamic provisioning of inter-call agent information. By adopting the SAF network service, the call control discovery feature allows
Cisco Unified Communications Manager to advertise itself along with other key attributes, such as directory number patterns that are configured in
Cisco Unified Communications Manager Administration, so other call control entities that also use SAF network can use the advertised information to dynamically configure and adapt their routing behaviors; likewise, all entities that use SAF advertise the directory number patterns that they own along with other key information, so other remote call-control entities can learn the information and adapt the routing behavior of the call.
