I have a AIO942.  I am trying to use the same phone number for faxing that also has an answering machine on it.  After reading the manual, it doesn't seem as though this is possible   If I enable receive faxes it says that the modem will answer all calls thinking it is a fax and calls will not go to the answering machine.  Does anyone use the AIO942 to receive faxes AND have an active voicemail/answering machine on the same phone line?  If so, PLEASE tell me how you have done it.
