[Asterisk-Users] Console as extension problems

[David Carter]

I'm trying to set up the console as an extension (so I can set up overhead
paging), but I can't seem to get it to work.  When I call my paging extension,
I get an error that it can't open the device:

    -- Executing Ringing("Zap/9-1", "") in new stack
    -- Executing Dial("Zap/9-1", "Console/dsp0|18|A(new/whistle)") in new stack
 << Call placed to 'dsp0' on console >>
 << Auto-answered >>
    -- Called dsp0
    -- OSS/dsp answered Zap/9-1

 << Hangup on console >>
  == Spawn extension (cmcm-internal, 6789, 2) exited non-zero on 'Zap/9-1'
    -- Hungup 'Zap/9-1'

To make sure it wasn't a permissions issue, I set the dsp0 device to 666:
crw-rw-rw-  1 root audio 14, 3 Oct 14 15:24 /dev/dsp0

The audio device works fine with sox, mpg123, etc.  I'm mystified about what
could be wrong with this.

Here's my oss.conf:

[general]
autoanswer=yes
context=paging
extension=s

The paging context in extensions.conf:

[paging]
; Using server sound card
exten => 6789,1,Ringing
exten => 6789,2,Dial(Console/dsp0,18,A(new/whistle))
exten => 6789,3,Hangup

; using paging module
;exten => 6789,1,Dial(Zap/17,18)
;exten => 6789,2,Hangup

System configuration:
Debian Sarge w/ Asterisk 1.0.1-1
T100P card going to Adtran TA750 channel bank with 5 FXS and 1 FXO card
  (analog extensions on FXS ports, FXO ports currently unused)
Trunks via IAX2 to Nufone

Any insights into this would be appreciated.

	Thanks,
	David
