Chapter 3: Telephone System Configuration
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 press 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 (e.g. 700), then complete the
transfer (such as by pressing send). The method using a VoIP phone will
vary depending on the phone.
At this point, the Asterisk Appliance 50 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 that was previously
specified by the Asterisk Appliance 50 prompt. 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.
Application Map
The Application Map tab gives you the ability to define a keypress
sequence which will execute a specific application, along with the
application’s arguments. One example of using this feature would be to
allow the caller or callee to playback a specific sound file on demand
when pressing a predefined key sequence. Click New Application Map
to define a new application map.
