[Asterisk-Users] Best quad-port fxo solution with EC?

[gw at adcomcorp.com]

Hello All,

I am trying to figure out which way to go for a quad port fxo solution
with a good echo can on it.  My options are the sangoma remora, a
mediatrix fxo, or something similar.

The issue is that I would need a good EC.  This would be on about a 9000
foot loop, and the lines don't function well on a spa-3000 or zaptel tdm
4 port card.

Anyone have experience that drives them in a certain direction when
considering a good ec on a quad port?

I tried this also with some fxo clones, but echo killed it.

Thanks,
Greg
