Found a solution! :-)


exten => 7654321,1,GotoIf($["${DEVICE_STATE(SIP/111)}"="INUSE"]?Busy,1)
exten => 7654321,n,GotoIf($["${DEVICE_STATE(SIP/222)}"="INUSE"]?Busy,1)
exten => 7654321,n,GotoIf($["${DEVICE_STATE(SIP/333)}"="INUSE"]?Busy,1)
exten => 7654321,n,Dial(SIP/111&SIP/222&SIP/333)


exten => Busy,1,BUSY(10)
exten => Busy,n,Hangup
