<DIV><FONT face=Arial size=2>Just moved over to DAHDI today and have a few
questions.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>My environment is:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Asterisk 1.4.22</FONT></DIV>
<DIV><FONT face=Arial size=2>Using a TE410P</FONT></DIV>
<DIV><FONT face=Arial size=2>4 PRI's</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. Now when calls come in on those PRI's I get this
message in the console:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>[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 face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>How can I resolve this? <BR></DIV></FONT>
<DIV><FONT face=Arial size=2>2. Do I need to be running echo cancellation on TDM
circuits? (PRI's?)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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 face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance,</FONT></DIV>
