There was a functionnality that when a key was not found in AstDB, a jump would be done to n+101. So the following would be OK:

exten = s,1,Set(forward_number=${DB(FORWARD/1234)})
exten = s,2,Background(one_local/forward/forward_number_is)
exten = s,3,sayalpha(${forward_number})
exten = s,4,Goto(s-report_mode,1)
exten = s,102,NoOp(Pas de valeur ce qui est normal)
exten = s,103,Goto(s-not_set,1)

But with my newly installed Asterisk 1.4.4, it doesn’t jump anymore. It continues to s,2 :-(.
So I guess I need to add a supplementary line to explicitely test the presence of the key:

exten = s,1,GotoIf(${DB_EXISTS(FORWARD/${F_EXT})}?:102)
exten = s,2,Set(forward_number=${DB_RESULT})
exten = s,3,Background(one_local/forward/forward_number_is)
exten = s,4,sayalpha(${forward_number})
…
exten = s,102,NoOp(Pas de valeur ce qui est normal)
