Cisco 400-051 Exam

Which Call Control Discovery function allows the local Cisco Unified Communications Manager to listen for advertisements from remote call-control entities that use the SAF network?

  • A. CCD advertising service
  • B. CCD requesting service
  • C. SAF forwarder
  • D. SAF enabled trunks
  • E. CCD registration service
Answer: Option B.
Explanation: 

SAF and CCD will allow large distributed multi-cluster deployments to have the directory number (DN) ranges of each call routing element advertised dynamically over SAF. Cisco routers act as SAF Forwarders (SAFF), while the call routing elements (e.g. CUCM) act as clients that register with the routers to advertise their DN ranges and listen to the advertisements of other routers.
