[Asterisk-Users] Send flash through zap channel

[C F]

I had to add this same feature recently for a client that has centrix
lines and wanted to use the conference feature of the centrix lines
which requires a flash, here is the setup:
PSTEN <> CENTRIX LINES <> ADIT 600 FXO CARD <> ASTERISK <> ADIT 600
FXS CARD <> AVAYA PARTNER ACS R6.
When someone is on the phone from the Avaya system they wanted to be
able to flash the centrix line. Here is my
/etc/asterisk/extensions.conf:

[pstn-in]
exten => s,1,Noop(${CALLERID(all)})
exten => s,2,Noop()
exten => s,3,Noop()
exten => s,4,Set(DYNAMIC_FEATURES=inflash)
exten => s,5,Dial(Zap/g2,,t) ;Zap/g2 is the FXS card on the Adit600

[avayaout]
exten => _1NXXXXXXXXX,1,Set(DYNAMIC_FEATURES=outflash)
exten => _1NXXXXXXXXX,2,Macro(dialoutbound,${EXTEN:1},,${LTRUNK})

[macro-dialoutbound]
exten => s,1,Noop()
exten => s,2,Dial(${ARG3}/${ARG1},,T)
exten => s,3,Goto(${DIALSTATUS},1)
exten => s,103,Goto(3)

Here is my features.conf:
[applicationmap]
inflash => *4,caller,Flash,()
outflash => *3,callee,Flash,()

When a call comes in and they want to flash the line then they press
*4, if they call out and they want to flash the line then they press
*3.

I had to put in the t or T above so that asterisk stays in the media
path and listens for the *3/4.
Keep in mind:
1. It doesn't matter if you put in T or t, both the caller and the
callee can press *3/4 to activate this features, in your case this is
a huge security problem. As someone that needs access to the door
could just press the door call button, and then use *3/4 above to
flash the line and get in.
2. The flash app only plays on FXO ports, which means that you might
have to play around with the inflash and outlash callee/caller
options.

I'm not sure if you have any FXO ports in your config, but if you
don't it wont work.

Hope this helps.
