Use Channel Roles to keep dispatchers from hearing each other in a channel if they are in the same room. This will help reduce any echo or feedback that is caused by users being in close proximity. Default users will still be able to hear all roles.
Select a channel you want to add user roles
Create a Default role that can Speak to anyone
Assign the Default role to all drivers
Create a Dispatcher role that Speaks to selected role Default
Assign the role to Dispatchers and hit Done. Your setup is complete
