Can you tell us what SVN checkout # and echo canceller you ended up using?
'dmesg' output when you load the module will tell you, as will ztcfg -v.

Since your EC only needs to support a tail long enough to handle the
PSTN part of the call, I suspect even fairly short tails are fine.

you try latest Asterisk 1.2.4 and Zaptel 1.2.3? Anyone has good feedback for

Nope only bad feedback here. The software EC in Asterisk worked much better for me than did the VPM on the TE411P.On 2/13/06, Isaac Xiao (KVB Kunlun Pty Limited)

Is the orion echo canceller a higher quality EC than tellabs?
Could be, but I don't see why one would spend more just becuase the
answer is yes. The tellabs will do the job perfectly (at least in my
experience) and can be picked up for less than $100.00 on eBay. They
have proven to last for 20 years (the older models being sold on eBay

The most common Tellabs EC are not the ones from the 80s, I was just
pointing out that the quality was good, since they still last now 20

Stagg - I know you get a full 128ms tail of echo can on the Sangoma. I
believe that on the TE411P, the 128ms tail is shared by all (4) spans,
and as you add additional spans up to maximum of 4, the echo can tail
amount decreases

Yes, I actually just removed the VPM. After doing so, I had echo at
the beginning of the call, but it trained out after a second at least
making it usable. I plan on contacting digium support this morning. Do
you know if there are any docs specific to this card or the vpm module
itself?
Kevin,
I have experienced the same issue. I get worse echo with the VPM
installed than with software EC. Have had it at 2 different sites with
2 different TE411P's.
