VCS752 Administrator and Provisioning Manual

Ensure you have specified the correct path to the firmware and configuration files 
on the 

SERVICING > Firmware Upgrade > Auto Upgrade

 page and the 

SERVICING > Provisioning

 page.

If the phone is not downloading a MAC-specific configuration file, ensure the 
filename is all upper case.

Provisioning: "Use DHCP Option" is enabled, but the VCS752 is not getting a 
provisioning URL from the DHCP Server.

Ensure that DHCP is enabled in Network settings.
