asterisk users - Apr 2006 - TDM400P: flash on analog phones doesn't work

Hi,

I have a TDM400P (31B) in a PIV 2.8, 512Mb ram, CentOS 4.3, zaptel 1.2.5
and Asterisk 1.2.7.1 and a couple of standard analog phones with a flash
button. A hook flash works fine for setting up a 3way call. But pressing
the flash button doesn't do anything. The zapata config is below. Anyone
have an idea what I'm doing wrong?

[channels]
context=local
usercallerid=yes
hidecallerid=no
immediate=no
transfer=yes
threewaycalling=yes
canpark=yes
echocancel=yes
busydetect=yes

signalling=fxo_ks
group=1
callerid="ANALOG1" <1001>
channel => 1

signalling=fxo_ks
group=1
callerid="ANALOG2" <1002>
channel => 2

signalling=fxo_ks
group=1
callerid="ANALOG3" <1003>
channel => 3

signalling=fxs_ks
group=2
channel => 4

Thanks and regards,
Patrick

Patrick,

Can you check your flash button interval? Some phones produce a very 
short pulse when you press the button, which may not be detectable by 
the PBX.

You can adjust the flash timing in zapata.conf
