To my knowledge there is no limitation that would cap that. The only limitation is that only one agent can login at a time. I don’t see a problem with that approach if they’re using the same workstation and phone since the first person would log out before letting the next person log into the computer.
FWIW- There are some 3rd-party utilities - Google it, I’ll refrain from a recommendation - that trigger an EM login/logout automatically when the computer is connected through the PC Port of a phone. They run at login/startup in the system tray, notice the phone through CDP, and then issue an EM API call for whichever user is actively logged in to windows. That would have the advantage of allowing the user to take calls somewhere other than the front desk if they ever need to.
