I'm using the following:

exten => 0145381068,1,NoOp()
exten => 0145381068,2,Gotoif($[${GLOBAL(SECUSED)}<10]?4)
exten => 0145381068,3,hangup
exten => 0145381068,4,Dial(SIP/1111 at sipoperator)
exten => 0145381068,5,Set(GLOBAL(SECUSED)=${GLOBAL(SECUSED)} + 
${DIALEDTIME})
exten => 0145381068,6,hangup


I place a test call of 20 secs, hangup, and I can place another call 
again through the same provider.
