[Asterisk-Users] where to buy x100p

[dean collins]

Why does the X100P have echo and the Wildcard TDM400P have no echo?

 

I thought the only advantage of using the TDM400P was that it used less
interrupts than the X100P?

Are there any other advantages?

 

 

 

Cheers,

Dean

Thanks for the tip. However, I have been trying evening after avening to


get the echo out by tweaking the settings. When I received the TDM11 I 

pulled out the X101P clone followed the example config at the Digium
site 

and I was up and running without any. I don't mind trying to play around


but wasting a lot of time on really cheap hardware was too much waste of


time when I look back :)

 

It's probably possible to get the echo out but it's not worth it for me
to 

figure it out :)
