Macro-dial-one throws ast_yyerror

I am running FreePBX 2.8.1
If i set call forwarding on queue member, and queue is set to “no follow me or call forward” I am getting ast_yyerror

Looks like this string from extensions_additional.conf:

exten => cf,n,Set(DEXTEN=${IF($["${CFIGNORE}"=""]?"${DB(CF/${DEXTEN})}#":"")})

Sets empty quotes.

I expect the general response will be “upgrade FreePBX.” Upgrade from 2.8 to 2.9 isn’t a huge change if you’re careful. Otherwise I’d put some debugging NoOp() or Log() calls in extensions_additional.conf to see if all those variables are getting set correctly.

I can tell you that line is identical in 2.10, but it’s hard to say which line causes the problem, since the error message isn’t pointing to a specific line.

The line in 2.10 that generates probably problematic string is identical:

$ext->add($mcontext,$exten,'', new ext_set('DEXTEN', '${IF($["${CFIGNORE}"=""]?"${DB(CF/${DEXTEN})}#":"")}'));

I’ve filed a bug:

Can anyone plz pay attention to the bug report? 2.11 is affected.
