Synopsis

Park and Announce

Description

Park a call into the parkinglot and announce the call over an extension.

  ParkAndAnnounce(announce:template|timeout|dial|[return_context])

• announce template: colon seperated list of files to announce, the word PARKED will be replaced by a say_digits of the ext the call is parked in
• timeout: time in seconds before the call returns into the return context.
• dial: The app_dial style resource to call to make the announcement. Console/dsp calls the console.
• return_context: the goto style label to jump the call back into after timeout. default=prio+1

Development (Jan 2006)

In the current Asterisk version, there is one parking lot per PBX. This leads to problems when you have multiple user groups in your PBX. With this patch, you can enable multiple parking lots, in order to

• Give each company using a virtual PBX it's own parking lot
• Give each department a parking lot
• Give a manager a parking lot that the admin also can access

Please test this patch to Asterisk 1.3 (svn trunk). Check out the multiparking module, compile and read the sample configuration. If you're happy, tell me. If you stumble into problems, tell me. The place to give feedback is the bug tracker, bug 6113.

New in Asterisk 1.4: Patch/bug 5779 adds hint support for the Local channel construct which allows for monitoring of the parking lot/ parked calls (by checking for existence of a dialplan extension).

Example 1

Blind xfer to parking:

exten => _2XX,1,Answer
exten => _2XX,2,Wait(1)
exten => _2XX,3,ParkAndAnnounce(pbx-transfer:PARKED|7200|SIP/${EXTEN:1}|default,${EXTEN:1},1)

The user on exten 11 may now blind xfer to extension 211. It waits 1 second, calls back with the parking number.

Example 2

Blind xfer to parking:

exten => 200,1,ParkAndAnnounce(pbx-transfer:PARKED|60|${BLINDTRANSFER:0:7}|internal_phones|${BLINDTRANSFER:4:3}|1)

Anyone with a 3 digit extension can blind transfer to 200 and it will call them back by pulling their extension from the ${BLINDTRANSFER} variable. I tested this on asterisk 1.4.

Example 3: Parking and BLF (busy lamp field)

In the basic settings of my Grandstream GXP-2000, I setup the Multi-Purpose Key to use Asterisk BLF and assigned it the parking lot extension (201 in our case, 701 by default iirc). I then added hints in the extensions.conf for the parking lot extensions:

exten => 201,hint,park:201@parkedcalls ; syntax for Asterisk 1.4 and newer
exten => 201,1,Wait(1)
exten => 201,2,ParkedCall(201)

Of course in features.conf I've defined the context as parkedcalls (context => parkedcalls). Hope this helps, it took a lot of piecing together other examples to get it to come together

Example 4

In asterisk 1.4.14: The hint should point to the extension AND context defined in "features.conf" NOT to a REAL extension as you would expect!
