[asterisk-users] mISDN Vs Dahdi

[Tamer Higazi]

Be sure, if you make us of HFC Boards that you have the zapfhfc patches.
There is some work for you to accomplish, like patching dahdi to make
use with the cheap isdn boards.

For office using ISDN Devices it's fairly enough. If you want to make
use of a server, I advise you to take the digium or sangoma boards,
because of the native support for asterisk.

If you don't love patching and searching to get what in the internet,
take Gentoo Linux. All included (don't use dahdi 1.5.x, still not
working on gentoo).
