how to automatic callback busy number from 12 button extension ?

i try #00*12

but didnt work ?
 
Would simply adding a "redial" button to the set suffice or are you looking for the system to auto dial a busy number ala "Busy Buster" from the Classic Merlin days?

I [love2] "FEATURE 00
 
callback in other pabx mean
when u call some one and u find him busy u ll dial code then on hock when the numberd u dialed be free the pabx give ringing to two extensions ( you and busy extension)
 
Callback provides an easy way to complete calls to busy extensions and, in Hybrid/PBX mode, to
outside numbers when all lines/trunks are busy in the pool through which calls are made.

 Selective. Callback is activated only when a caller chooses it by dialing a feature code or, on
multiline telephones, by pressing a programmed Selective Callback button. On 4412D+,
4424D+, 4424LD+, and MLX display telephones, a caller can also select the feature from the
display.

When a caller wishes to use Selective Callback for a call and reaches a busy extension, he or she
must activate Selective Callback while listening to the busy signal. If the caller tries to make a call
by using a pool in which all lines/trunks are busy, he or she hears a fast busy signal immediately
after dialing the pool dial-out code. After activating selective Callback, the caller hears the queuing
tone and the call is added to the Callback queue

With both types of Callback, a caller can either stay on the line until the call is completed or hang
up.
 If the caller stays on the line, the red and green LEDs next to the line button are lit. When the
busy extension or pool is available, the caller hears the out-of-queue tone (three short beeps)
and the call is completed automatically.
 If the caller hangs up, the green LED next to the line button flashes, indicating that the button
is being held for the queued call. When the busy extension or pool is available, the caller hears
a priority ring (three bursts and one long ring on a 4400-Series, MLX, ETR, TransTalk 9031/
9040, Business Cordless 905, or MLS telephone). If the user does not answer the callback call
within the number of rings programmed for the system (1–6), the Callback request is
cancelled.
For inside and outside calls, the caller hears ringback when the extension is available, but the
system does not make the call until the caller picks up.

Other Multiline Telephones
On all other multiline telephones, Selective Callback is activated by pressing a programmed
Callback button, by dialing #55, or by pressing the Feature button and dialing 55. On 4412D+,
4424D+, 4424LD+, and MLX display telephones, Selective Callback is also activated by pressing
the Feature button and selecting the feature from the display. If you are on another call when the
system tries to call back, you hear an abbreviated ring.
On a multiline telephone, you can queue more than one call to the same extension.
On a multiline telephone, cancel a callback request by pressing the SA or ICOM button used to
make the call, lifting the handset, pressing the Drop button, and pressing the SA or ICOM button
again. The red and green LEDs next to the button go off, and the request is cancelled.
4400, 4400D, and Single-Line Telephones
A 4400, 4400D, or single-line telephone user can make and receive other calls while waiting for
the call to be completed. The request remains in the queue until the user who initiated the request
is available. Queued calls ring at a 4400, 4400D, or single-line telephone in the order in which they
were queued.
A 4400, 4400D, or single-line telephone can queue only one call at a time. If a 4400, 4400D, or
single-line telephone user who has already queued one call tries to transfer a second call to a busy
pool, the transferred caller hears a fast busy tone. The system considers the transfer complete,
and the call is not returned to the 4400, 4400D, or single-line telephone user who transferred the
call.
Cancel a Callback request by lifting the handset and dialing #*55 while listening to inside dial
tone. The system sends a confirmation tone to indicate that the request is cancelled.
A 4400, 4400D, or single-line telephone user cannot use Callback if another call is on hold. A
waiting outside call rings at a 4400, 4400D, or single-line telephone before any calls queued for
that extension.
