Special EHS Setup For Cisco Phones

With most phones, you can change the settings for EHS (Electronic Hookswitch) on the phone itself. However, for certain phones, such as the Cisco phones listed below, you will need to go into the Cisco internet portal to change them. This may only be accessible by your IT Team.
