How can I disable international calls on wgw1002g

[rtg-DE_out-1]
exten => _0049.,1,NoOp( _0049. matches Rule rtg-DE_outg-1)
exten => _0049.,n,Set(CDR_CALLEEID=${EXTEN})
exten => _0049.,n,GrpPolicy(RO_gsm_all)
exten => _0049.,n,Macro(dial-failover,,${EXTEN},${POLICY_DE_gsm_set})
exten => _0049.,n,Goto(nocdr,s,1)

GREAT! Thanks hua,

How can I extend this and add another option - just to use numbers with 0 zero ...something like _0Z. ?

I can copy this and put it after that just will change _0049. to be _0Z. this will allows only numbers with one 0 at the begging but ...what about the order of the dial plan applications? Should I add it again with 1 n n n or they should be just again with n n n n

add it again with 1 n n n like this .

Thanks hua, it works well now
