Ok Thank you Tamer. <br><br><div class="gmail_quote">On Wed, Sep 21, 2011 at 4:32 PM, Tamer Higazi <span dir="ltr"><<a href="mailto:th982a@googlemail.com">th982a@googlemail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
Be sure, if you make us of HFC Boards that you have the zapfhfc patches.<br>
There is some work for you to accomplish, like patching dahdi to make<br>
use with the cheap isdn boards.<br>
<br>
For office using ISDN Devices it's fairly enough. If you want to make<br>
use of a server, I advise you to take the digium or sangoma boards,<br>
because of the native support for asterisk.<br>
<br>
If you don't love patching and searching to get what in the internet,<br>
take Gentoo Linux. All included (don't use dahdi 1.5.x, still not<br>
working on gentoo).<br>
