Hylafax has that capability. Quoting from one of its man pages:
,----< excerpt from hylafax-server(5) >
| HylaFAX supports a simple form of access control for receiving facsim‐
| ile. Each faxgetty process may be configured to check the Transmission
| Subscriber Identifiers (TSI) of the remote fax machine against an
| access control list, typically etc/tsi. Only if the TSI is matched by
| a regular expression pattern in the file, is the remote machine permit‐
| ted to transmit a document. This mechanism can be used, for example,
| to guard against junk fax.
`----
You will need a Linux or BSD box for the hylafax server. It can be a
virtual, provided it has sole access to the modem.
If you run windows, there is a hyla client at:
http://wphfforwin7.sourceforge.net/
which will make sending easier.
