[asterisk-users] how to avoid call waiting? Or check DIALSTATUS before Dial()?

I have two internal analogue extensions off a TDM400P. If the first is 
busy, I'd like to ring the second. So:

[incoming]
exten =>s,1,Answer()
exten =>s,n,Dial(${mainline},60)
exten =>s,n,ExecIf($["${DIALSTATUS}" =
"BUSY"]?Dial(${secondline},30))

But it doesn't work because * first tries Call Waiting on the main line. 
Here I dial out:

     -- Starting simple switch on 'DAHDI/1-1'
     -- Executing [140 at internal:1] Answer("DAHDI/1-1",
"") in new stack
     -- Executing [140 at internal:2] Set("DAHDI/1-1",
"CALLERID="house"
<2127873453>") in new stack
     -- Executing [140 at internal:3] Dial("DAHDI/1-1",
.............................

And now an incoming call:

     -- Executing [s at incoming:1] Answer("IAX2/nhi-10929",
"") in new stack
     -- Executing [s at incoming:2] Dial("IAX2/nhi-10929",
"DAHDI/1,60") in
new stack
     -- Called 1
     -- IAX2/nhi-10929 requested special control 20, passing it to DAHDI/1-2
     -- IAX2/nhi-10929 requested special control 20, passing it to DAHDI/1-2
     -- IAX2/nhi-10929 requested special control 20, passing it to DAHDI/1-2
     -- DAHDI/1-2 is ringing
     -- IAX2/nhi-10929 requested special control 20, passing it to DAHDI/1-2
     -- IAX2/nhi-10929 requested special control 20, passing it to DAHDI/1-2
     -- CPE supports Call Waiting Caller*ID.  Sending 'Seandarcy/212 573 
1432'


Is there a way to check the status of a dahdi channel _before_ dialing it?

exten =>s,n,ExecIf($["DAHDI/1${DIALSTATUS}" = 
"BUSY"]?Dial(${secondline},30)) ??

What's special control 20  ??

Any help appreciated.

exten =>s,n,Dial(DAHDI/g5,60)

For both channels set: group = 5

Disabling that can also help.

You check for BUSY. Check for IN_USE instead. That's what I do here (on 1.4,
but I guess that 1.6 behaves similarly).

When an extension is in IN_USE state I have a decision tree after consulting
a database:


   - If the user wants waiting call - dial him/her/
   - If the user doesn;t want waiting call but wants voicemail answer - send
   to voicemail with B prefix.
   - If niether is wanted - play busy.

                      Regards, __Yehavi:
