Re: [hylafax-users] called-number ID

[Moritz Both <mb@aldebaran.de>]

Yan,

if half the support people admit that it is easy, maybe you can get
them to talk with each other somehow... sending MSNs is an essential
part of isdn, as far as i understand. There are bri lines without msn
in some countries, but this makes sense only if you have only one
phone number for the line. Since you have a number block, you must
have msns or you cant distinguish the numbers in the number block...

more questions - which operating system do you plan to use? Does
hylafax support the os and isdn board combination at all? You will
need some kind of modem emulation provided by the board driver.
