Fake FAX Calls

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

Hi,

as the docs say, some modems are just too dumb to properly distinguish
between fax and data -- everthing that is not data (voice, for example,
or a very old data modem, or something along that lines) is reported
as "I have identified this as a fax!!!".

There is nothing you can do about it, except hit your modem vendor
with something long and hard, and have them fix their modem firmware...
