[asterisk-users] tdm410p w/ echo - no full duplex

[Michael J. Liberatore]

hi, i just installed 2 new tdm410p's on asterisk 1.4.19 with zaptel
1.4.10.  They have the hardware echo cancellers.  I am having an issue
though, when i talk, it cuts out the other end.  So for example, i
called up another asterisk box and was listening to the prompts and as
they were playing if i said something, it would cut out the other end.  
 
so i basically started counting and for the 20 seconds i counted,
nothing came through from the otherside.
 
i tried from multiple phones and this didnt happen with the old tdm400.

 
is this an issue with the card?  Is it because zaptel has mg2 on?  Does
than mean i am using 2 echo cancellers?  the hardware one and the mg2?
how should this be set?  also, it says  "echo canceller could not be
trained" or something like that at the start of every call on the cli.
 
 
 
thanks
 
mike
