Re: [hylafax-users] problems to send faxes to European ISDN-fax/phone

[Uwe Maier <umaier@xxxxxx>]

Hi Chris,
in europe you normally get a couple of MSNs together with the ISDN line 
(and you even get a couple more if you want).
So usually we use a different phone number for the fax machine.

In the early days of ISDN there were fax machines called "group 4" which 
were digitally connected with 64kbit/s but they seem to be vanished 
since they were quite expensive and not always compatible with the 
existing "group 3" faxes. These fax machines were capable of detecting 
an incoming fax by it's service flag.
In "group 3" everything looks like "voice" and there's no way to 
determine upfront if it's a person or a machine calling.

So all in all: ask for the correct phone number - people with digital 
lines usually spend a dedicated one to their fax.

Regards,
uwe
