[Asterisk-Users] TDM 2400 With 24 FXO

[f6hqz-m at hamwlan.net]

Hello Fernando,

I have checked this card with and without hardware echocan : the hardware
echocan module does the job better than the zaptel software can do it. I
recommand this module without any doubt.

But, the echocan algorithms in zaptel are better and better and the CPUs
power grows permanently.

It is possible to use this card without hardware echocan, but you will
encounter the same results, in this case, as you can obtain with the other
TDM Digium's cards : correct for certain situations, not for all extreme
cases, depending what listening level your users want, lines specifications
and what critical echo threshold they can admit before to not be able to do
correctly their job.

Near same thing for E1/T1 harware echocan features.

Best Regards,
Francois BERGERET,
France.

Hi,

Have someone there tried the TDM 2400 with 24 FXO? Have had echo problems?
or any other problem ?  Recommendations? Optional echo cancellation modules
are necessary?

TIA, 
Fernando
