Echo free tdm cards. What has changed in five years?


#1

It has been a long ten years since I started with asterisk, then abruptly gave up on it for its voice compression or most notably, voice echo and volume control issues.
I want to know now, if there is a simple single or duel line product that digium makes that totally eliminated the echo or voice volume issues that I constantly had to change and tweak? I DO not want to hear any complaints from anyone that I make or sell a system to regarding this matter. Once my system is together and running 100% , I want to forget about it!

Thanks a bunch!

There is no way of totally eliminating echo.

Hi James,

10 years ago, all of the echo cancellation was done in software by cancelers that aren’t up to scratch. What Digium card were you using at the time?
