[Asterisk-Users] logic problem with GotoIf?

[Rich Adamson]

Trying to implement a simple mechanism to enable / disable the ivr menues
while in the office and having a logic problem (brain fart).

Call comes in via x100p in the "inbound-bus" context of zapata.conf

In extensions.conf, I've got:
; activate the ivr by dialing this extension                   
exten => 3950,1,Wait(1)                     
exten => 3950,2,DBput(FEAT/ivron=yes)
exten => 3950,3,Hangup               
                                                                     
; deactivate the ivr by dialing this extension
exten => 3951,1,Wait(1)
exten => 3951,2,DBdel(FEAT/ivron)
exten => 3951,3,Hangup

[inbound-bus]
exten => s,1,GotoIf(DBget(FEAT/ivron) == yes?bus-ivr-main|s|1)
exten => s,2,Dial(${PHONE1}&${PHONE2},15)

[bus-ivr-main]
exten => s,1,Wait,1
exten => s,2,Answer
exten => s,3,DigitTimeout,5
exten => s,4,ResponseTimeout,20
exten => s,5,Background(npi-greeting)  ; "Thanks for calling press 1 for"
 <snip>

I call x3951 and the DBdel is executed. 
When a call arrives, the CLI shows...
Mar  9 11:49:18 NOTICE[1226054960]: chan_zap.c:4607 ss_thread: Got event 2 (Ring/Answered)...
 -- Executing GotoIf("Zap/2-1", "DBget(FEAT/ivron) == "yes"?bus-ivr-main|s|1") in new stack
 -- Goto (bus-ivr-main,s,1) 

Looks like the GotoIF is not doing what I thought it would. Is my logic
messed up?

Thoughts?
