[Asterisk-Users] flash button on asterisk + legacy pbx system

[Giorgio Incantalupo]

Hi C F,
ok, I also thought to make the user to press some keys for example * and 
3 so I setup a little test made using an Asterisk box with a TDM400P (2 
FXS + 2 FXO) connected to an analog phone (fxs port) and an analog line 
(fxo port).
I searched on internet and found some interesting stuff so I made my 
extensions.conf:

My extension.conf is (in brief):
[zap]
exten => s,1,Set(DYNAMIC_FEATURES=zapflash)
exten => s,2,Dial(Zap/3,15,tw)      <------- Zap/3 is my analog phone
exten => s,3,HangUp

My zapata (Zap/1 is the line and Zap/3 is the phone):
context = zap
language = it
signalling = fxs_ks
threewaycalling=yes
transfer = yes
channel => 1

language = it
signalling = fxo_ks
callerid = "tel1" <100>
threewaycalling=yes
transfer = yes
channel => 3

and my features.conf:
[applicationmap]
...
zapflash => *3,caller,flash,()

When I call the number xxxxxxx, Asterisk answers on zap line passing the 
call to zap/3. I pick up zap/3 phone and then I press *3 but all I get 
is (on asterisk console):

WARNING[3082]: app_flash.c:101 flash_exec: Zap/3-1 is not an FXO Channel

Why? It seems Asterisk sends Flash command to the phone but it is not 
what I want.
Is this the right way to follow? Press *3 (or other code) to send 
command to host pbx while the callee is on the phone? Is this what you 
meant? If yes, why Asterisk does not send the flash command to the line?

Thanks for patience
