[asterisk-users] Question about OSLEC or HPEC with AsteriskNow

[Martin Roy]

I was previously using an old computer running Asterisk 1.2 with  
zaptel. Once the CPU fried I switch to a new computer and I chose  
AsteriskNow 1.5 running in 64bits to simplify the installation  
process. I manage to find my way with configuring dahdi instead of  
zaptel and to switch all my previous config to the new computer. Now  
everything is fine except that even if I use the md2 echo cancellation  
it's not perfect I still have echo issue. So I made some search around  
and found that there's oslec and hpec out there that seems to be  
better then what I'm currently using. So my question should I use hpec  
or oslec with my TDM400 card? I also tried to recompile dahdi to use  
oslec (before I found that Digium had hpec) but then I get an error  
message that the source of my kernel cannot be found so I can never  
actually compile a new version of dahdi.

Thanks
