Something like

exten => 5555551111,1,Verbose(Door buzzer calling)
same => n,Set(toRing=)
same => n,ExecIf($["${DEVICE_STATE(SIP/user1)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user1)
same => n,ExecIf($["${DEVICE_STATE(SIP/user2)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user2)
same => n,ExecIf($["${DEVICE_STATE(SIP/user3)}" = "NOT IN 
USE"]?Set(toRing=${toRing}&SIP/user3)
same => n,Dial(${toRing:1}) ;to remove the first &

would do the work
