Prerequisites for Call Home

To support the Cisco Cisco Unified Communications Manager Call Home service, you require the following:

• A Cisco.com user ID associated with a corresponding Cisco Cisco Unified Communications Manager service contract.

• It is highly recommended that both the Domain Name System (DNS) and Simple Mail Transfer Protocol (SMTP) servers are setup for the Cisco Cisco Unified Communications Manager Call Home feature.

  • DNS setup is required to send the Call Home messages using Secure Web (HTTPS).

  • SMTP setup is required to send the Call Home messages to Cisco TAC or to send a copy of the messages to a list of recipients through email.
