FAS on recordings

I am using Quintum AXT, i am using loopstart as my signaling and answer disconnect supervision, i am facing a problem is that any automatic response on the line , the quintum will issue a connect, eg. Automatic response says: the mobile you are calling is out of coverage area.etc…. 😕
with this i m using Gnugk as a gatekeeper if it is possible that we dont charge on recording then it will be gr8. otherwise tell me wat other wayout my carrier says that other providers dont charge on msgs
