[SR-Users] Authentication using a PSTN phone

Hi, I have a service that requires a user to authenticate, in order to bill him at the end of the service. I also need real- time check of the balance during a call, in order to signal when the amount is too low to continue the call. Is this possible with SER? Thanx, Miguel Tadeu
