EC needed in all-digital situation?
I was just told that for my forthcoming system I will be getting a data
T-1 instead of a voice T-1. Given that all of the handsets will be voip
phones, no analog at all, do I need echo cancellation? I looked at the
voip-info wiki and it seems to me that the answer should be "no" but I
would like to confirm that.
TIA,
W
