<extension name="group-intercept">
      <condition field="destination_number" expression="^\*8$">
 <action application="answer"/>
 <action application="intercept" data="${hash(select/${domain_name}-last_dial/${callgroup})}"/>
 <action application="sleep" data="2000"/>
      </condition>
</extension>
