Hybrid work has turned the assigned desk into the exception. Whether you call it hot desking, hoteling or flex working, the question for IT is the same: how does a phone become my<\/em> phone the moment I sit down? Cisco now offers two answers, depending on where your calling platform runs.<\/p>\n

Cisco has invested steadily in the cloud route. Since PhoneOS 3.3 hot desking sign-in no longer requires a reboot, and since PhoneOS 3.6 (November 2025) only the user who reserved a desk through Cisco Spaces can sign in on it. Cisco Spaces Smart Desking lets employees book desks up to 14 days ahead and check in with a QR code.<\/p>\n

The gap for on-premises customers<\/h3>\n

Many organizations in banking, government and healthcare keep their calling on CUCM for security, compliance or integration reasons. For them, Extension Mobility is the<\/p>\n

Extension Mobility vs hot desking<\/p>\n

hot desking engine, and it works well. Its weak spot is the sign-in itself: typing a user ID and PIN on a keypad is slow, easily skipped, and a common reason employees remain reachable on the wrong desk, or not at all.<\/p>\n

Single sign-on closes that gap<\/h3>\n

ALM Pro links Extension Mobility to the Windows login. When an employee signs in on a laptop at a flex desk, the Cisco phone on that desk logs in to their device profile automatically. When they sign out or lock the computer, the phone logs out . Users can also log on by scanning a QR code with their smartphone. No PIN codes, no forgotten logouts, and no change to your CUCM platform.<\/p>\n

The result is the same experience Webex Calling users get from hot desking, on the platform you already own.<\/p>\n
