[asterisk-users] TDM2400 Hardware Echo Cancel (Adam Sharples)

[Giuffredi]

Hi Adam,

 

 

I have the same problem.

 

Are you sure is an echo canceller problem?

 

 

Following advices from this list I discovered that I had an IRQ shared.

 

Untill now I didn't try the new setup but I really hope that this was the
problem.

 

If you manage to solve the problem in any way please give me advise.

 

Ciao

 

 

 

 

You can make sure the card is sitting on it's own IRQ - use the command

 

   cat /proc/interrupts

 

 

You can also check that the card isn't losing interrupts by running the
zttest proram:

 

   /sbin/zttest

 

 

There's more on interrupts here:

It's aimes at the TDM400P card, but I'd be surprised if the 2400P is that
much different (but someone please correct me if it is!)
