Call Parking

Call parking is an Asterisk feature which allows a user to place a call on hold so that it can be taken off hold from another extension. The Call

Parking page gives you the ability to define the call parking options which will enable use of this feature.

Number of Seconds a Call Can Be Parked - The number of seconds a call can be placed on hold. After the time has elapsed the call will ring the originating extension.

Parking a Call

You can park a call using either an analog or VoIP phone. To use an analog phone, hit the flash button, or quickly click the hook switch, wait for a dial tone, then dial the extension (700). With a VoIP phone, initiate the transfer, dial the call parking extension (i.e. 700), then complete the transfer (such as by click send). The method using a VoIP phone will vary depending on the phone.

At this point, the appliance will prompt you with a number. The number it prompts you with is the number from the pool specified. This is the number that can be entered to retrieve the call. To retrieve the call, pickup a phone, and dial the parking number specified by the appliance. The amount of time that the call remains parked is determined by the number of seconds specified. If the call is not retrieved in this time, the call will be redirected to the user that originally parked the call.

Note: In order to properly park a call, you must use attended transfer functions. Using a blind transfer function will not provide the parking number to the person parking the call. This makes recovery of the call impossible, except for the fall through timeout.
