I am trying to set up CAS signalling on my single E1/T1 digium card. I installed things in the following order
<br>
<br>1. libpri-1.4.11
<br>2. dahdi-linux-complete-2.4.0+2.4
<br>3. openr2-1.3.0.tar
<br>4. asterisk-1.6.2
<br>My <a href="http://system.com">system.com</a> is as follows
<br>
<br>/etc/dahdi/system.conf
<br>
<br>loadzone = in
<br>defaultzone = in
<br>span = 1,0,0,cas,hdb3
<br>bchan = 1-15,17-31
<br>dchan = 16
<br>
<br>when i do a service dahdi restart i get the following error
<br>
