The most likely reason for a user not seeing the phone call icon on the left pane is that the user is not assigned the appropriate role. A role is a collection of permissions that define what a user can do or see in Genesys Cloud CX. A permission is a granular setting that controls access to a specific feature or function. To make or receive calls in Genesys Cloud CX, a user needs to have certain permissions assigned to their role, such as Telephony > Plugin > All and Telephony > Call > Control > All. If a user does not have these permissions, they will not see the phone call icon on the left pane and will not be able to use telephony features.
