Does HPEC make that much difference?

I have a couple of Asterisk 1.2.x servers both with TDM02B cards with two PSTN lines each. Everything is working pretty good. I was just reading about the HPEC program that Digium has. Is this something I should get? Is it really that big of a difference? Will I notice the difference? I don’t really have all that much problem with echo, sometimes, but not unbearable.

I use OSLEC which works pretty well… and it’s free and Open Source

If you have echo, it will get rid of it. Some people have had lots of echo on all calls where HPEC cleared it all up.

Yes ! HPEC make big different with your systems
