<div><font size="2" face="Arial">Just moved over to DAHDI today and have a few
questions.</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">My environment is:</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">Asterisk 1.4.22</font></div>
<div><font size="2" face="Arial">Using a TE410P</font></div>
<div><font size="2" face="Arial">4 PRI's</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">1. Now when calls come in on those PRI's I get this
message in the console:</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">[Dec 6 19:42:18] WARNING[31557]:
chan_dahdi.c:1481 dahdi_enable_ec: Unable to enable echo cancellation on channel
41 (No such device) </font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">How can I resolve this? <br></font></div>
<div><font size="2" face="Arial">2. Do I need to be running echo cancellation on TDM
circuits? (PRI's?)</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">3. I compiled DAHDI tools and I seem to have all
the scripts, however I do not have or can not seem to find dahdi_tools. How can
I get this? I believe this is the zttools replacement.</font></div>
<div><font size="2" face="Arial"></font> </div>
<div><font size="2" face="Arial">4. Is there a way for me to verify that I am
receiving clock source on these PRI's from the telco? I need to verify this
because it seems that if I use my internal clock source my HDLC errors seem to
go away. (Still testing)</font></div>
