In this situation my telco want to be 112 (EU emergency call) a 
subscriber and everithing is OK. Do you restart asterisk after replacing 
settings in your config? And i think your dialplan will be like this
_1XX             => {
                                 Dial(DAHDI/g2/1${EXTEN},60);
                                 Hangup;
                             }

And look may be you were wrong with settings with differents group ?
