If I understand you, then yes you can. I do this now. All our telco
lines come through our analog NEC phone switch and then through FXO/
FXS ports to my Asterisk. Asterisk handles voicemail and the menu
system so when somebody dials "6" to get my extension the asterisk
does the following:
Flash();
Wait(0.4);
SendDTMF(268);
Hangup();
I added the Wait(0.4) as I found that under heavy load the NEC would
not catch the first DTMF digit after the Flash. This solution has
worked for us for over a year now.
Some "bonus" information that may or may not be relevant to what you
are doing:
We have a few SIP phones that we needed to be able to do the same kind
of thing. We couldn't flash transfer to the Asterisk, but in the NEC
I setup a outgoing trunk line (dial 8 to access) that goes to the
Asterisk box. Then I setup a "forward all calls" on extension 268
(when I have my SIP phone active) to "dial out" to 8268. That way
when somebody calls my extension it automatically forwards then to
extension 268 on the Asterisk box.

Hi to All, I have a PBX (MAINPBX) from a Telecomm Provider, which
have the feature to transfer calls (Incoming call -> Answer -> FLASH
-> Dial Number to transfer -> Answer -> FLASH+4) and the call is
transferred, but I have the need to implement an internal ACD using
Asterisk as the PBX, the trunks connected to my Asterisk FXO ports
are Extensions of my MAINPBX (ex., 5437, 5440 etc), all features
work fine, but I have the need to make asterisk act as a normal
telephone when transferring calls, I need to release the line (FXO
port in my Asterisk) and make the transfer via the MAINPBX feature.
Otherwise I will use 2 lines of my Asterisk PBX to make the transfer
and it reduce the incoming lines available for my ACD.
It’s possible send the commands FLASH, FLASH+4 using the incoming
line to my MAINPBX via Asterisk like a normal telephone?
Thanks in Advance.
