My solution to this problem was to use a gotoif and check if 
PJSIP_DIAL_CONTACTS has any contacts before trying to dial, if it does 
not then I skip the dial and goto the next step.  So:

exten => 1001,1,GotoIf($["${PJSIP_DIAL_CONTACTS(${EXTEN})}" = ""]?nocon)
exten => 1001,n,Dial(${PJSIP_DIAL_CONTACTS(${EXTEN})})
exten => 1001,n(nocon),SomethingElse
