The time on my Cisco phone is not correct

You must make some manual changes to your Cisco phone's configuration file (SIPDefault.cnf) in order to properly get the time from a network time server via NTP.

The following requires knowledge of the Linux OS and the command line!

1. Login to your system as root
2. Type: cd /tftpboot
3. Press the Enter key
4. Type: vi SIPDefault.cnf in order to begin editing the file using the VI text editor (Learn about VI)
5. Type: /sntp_mode
6. Press the Enter key
7. Change the word DirectedBroadcast to anycast
8. Press the ESC key
9. Type: :wq!
10. Reboot your Cisco phone

Your changes will be overwritten if you make any changes to the Extensions page within your Admin Panel.  You will have to follow the steps above to reset the configuration option for NTP.
