Unified Communications Manager and provides a

 

 

phone with its load ID. After obtaining the file

 

 

from the TFTP server, the phone attempts to make

 

 

a connection to the highest priority Cisco

 

 

Unified Communications Manager on the list. If

 

 

security is implemented, the phone makes a TLS

 

 

connection. Otherwise, it makes a non-secure TCP

 

 

connection.

 

 

If the phone was manually added to the database,

 

 

Cisco Unified Communications Manager identifies

 

 

the phone. If the phone was not manually added to

 

 

the database and auto-registration is enabled in

 

 

Cisco Unified Communications Manager, the

 

 

phone attempts to auto-register itself in the Cisco

 

 

Unified Communications Manager database.

 

 

Note Auto-registration is disabled when security

 

 

 

is enabled on Cisco

 

 

 

Unified Communications Manager. In this

 

 

 

case, the phone must be manually added to

 

 

 

the Cisco Unified Communications

 

 

 

Manager database.
