    I wrote the last Friday that I've Problems with de ModemSetupAACmd:
    AT+FAA=1 because when it's in my config file the system accept only
    Data calls appropriately, and when it isn't in the config-file the
    system accept only FAX call.
    
    I've  received an answer for my problem that say:
    
    Some modem require +FCLASS=0+FAA=1 to do answer correctly.
    
    Y think that's mean set ModemSetupAACmd:  AT+FCLASS=0+FAA=1 in
    config file, but it doesn't work.

I know of only two modems that correctly support adaptive-answer with
Class 1 operation: ZyXEL 1496 (and probably 2864 but never tried) and
the Motoroloa Lifestyle.  Your modem is not correctly implementing
adaptive-answer; it is switching into Class 2 mode when a fax call is
received.  HylaFAX does not support split operation; e.g. outbound with
Class 1 and inbound with Class 2/2.0.  Either configure the modem to
operate as a Class 2 modem or do not use the modem's adapative-answer
support.
