Why does the desk phone stay in the Remote In-Use state for up to 30 seconds after the user hangs up the cell phone?
A. After hanging up the cell phone, the calling party hears the reorder tone and the desk phone stays in the Remote In-Use state for up to 30 seconds before moving to the On-Hold state. The desk phone can then resume the call with the calling party. The delay occurs because the mobile carrier waits before sending a disconnect message to Cisco Unified Communications Manager, probably to avoid false disconnects.
