[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|00:00-16:00|mon|*|*
include = closed|02:00-16:00|tue-wed|*|*
include = closed|02:00-16:00|thu|*|*
include = closed|02:00-11:00|fri|*|*
include = closed|04:00-11:00|sat|*|*
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:

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

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. 

Jeff

I think you need a longer period of time and that is why the mp3 is
okay. For the mp3 to play, you have time to crank up mpg123 and the
buffering and then playing. All this gives plenty of time for the analog
line to come up and start passing the audio before you flash. The beep
would be a short enough time itself to possibly interfere with the
amount of time to get the line picked up. 

I suggest you put the wait after the answer and then beep if you want to
see it do something, then flash.
