How to Configuring Call Parking in Call Manager Express?

Typically, when you place a call on hold, you can retrieve the call only from the original phone where you placed the call on hold. Shared-line systems bend the rules a little by allowing you to retrieve the call from any phone with the same shared line assignment. The call park feature takes this one step further by allowing you to retrieve the call from any phone in the organization. Call park "parks" the caller on hold at an extension rather than on a specific line. Any IP phone that is able to dial the park extension number can retrieve the call. The call park system works by finding free ephone-dns in the Cisco Unified CME configuration that you have not assigned to an IP phone and have specifically designated as a call park slot. You can either allow CME to park calls randomly at the first available ephone-dn or allow users to choose the extension where the call is parked. Each of these scenarios fits different environments. Calls being parked at random extensions might work well for a warehouse environment with a voice paging system. When an employee has a call, the receptionist could announce, "Larry, you have a call on 5913" over the loudspeaker, at which point Larry could go to a phone and dial the extension to pick up the call on hold. Choosing extensions would work well for an electronics superstore in which each department responded to a known extension number. For example, software could be extension 301, cameras could be extension 302, and so on. The receptionist can then park multiple calls on a single call park number (this would require multiple ephone-dns assigned the same extension). As the specific department retrieves the calls, CME would distribute them in the order in which they were parked. The call parked longest would be answered first. You can configure call park simply by adding an ephone-dn designated for call park purposes. Example 6.6 creates two ephone-dns designated for call park.
