[Asterisk-Users] Problem flashing zap channel.

[Jeff Pratt]

Hello All,

    I've got Asterisk CVS-HEAD-11/03/04-14:36:44 installed and running.  
I have a TDM04B (wildcard with 4 FXO modules) using fxs_ks signalling 
(I'm under the suspicion that my lines (2500 lines from a Nortel 
Option11 PBX) are merely loopstart, but that's a side issue (which, if 
anyone knows for sure, would be nice to know)).

I have a fairly simple extensions.conf consisting of:

[open]
exten => s,1,Wait(1)
exten => s,2,Answer
exten => s,3,MP3Player(/var/lib/asterisk/sounds/P73_hoho.mp3)
exten => s,4,Flash()
exten => s,5,SendDTMF(1300)
exten => s,6,Hangup


[closed]
exten => s,1,Wait(1)
exten => s,2,Answer
exten => s,3,Background(beep)
exten => s,4,Flash()
exten => s,5,SendDTMF(7112)
exten => s,6,Hangup


[default]

include => closed|04:00-11:00|sun|*|*

include => open


When I make a call during the open hours, no problems.  and I get this 
output from the console:

Connected to Asterisk CVS-HEAD-11/03/04-14:36:44 currently running on

HOWEVER;  when I call during the closed period, it doesn't go so well:

asterisk1 (pid = 1521)

I put the Background(beep) in because asterisk wasn't even picking up 
the line previously.  I'd tried a NoOp before that, and it made no 
difference.

Can anyone tell me how to make this work?  Any patches (in or out of 
CVS) to app_flash.c that relieve this issue?  I'll be trying a 1/4 
second silent mp3 shortly.

Thanks.
