When we talk about VoIP (I mean pure VoIP) there is no need for Digium
cards. All the major and minor players support SIP. <br>
I have never worked with any card. So cant say much about them. <br>

Thank you for that great explanation Jal<br>
<br>
So I would have to use Digital PSTN lines for large installations
right? I<br>
have to see if Digital is available in the area. If I would have to use
2<br>
Asterisk boxes would I need 2 digital PSTN lines?<br>
