[asterisk-biz] hdwr v. sftwr v. no echo cancellation
Dear List, As we bring up * and migrate from the legacy PBX, its important for my management to experience good quality voice. Question is whether to use Digium's hardware echo cancellation, Digium's software echo cancellation, or no echo cancellation, on the 8 port FXO card (Digium TDM800P) I am thinking of using during the initial turnup and migration. Recommendation?

DEFINITELY use hardware echo canc... otherwise you may be upset with the quality of some calls.

Definitely buy hardware echo cancellation, the time and credibility savings are worth the cost.

Actually, I would agree with you most of the time, but for 8 or less channels that you will be using with Digium's TDM800P either choice would work. The main consideration is the amount of CPU power that your system has. The hardware echo cancellation module and the HPEC (High Performance Echo Cancellation) software use the same algorithm. Either way you will be using the same ATT certified, toll-quality, G.168 compliant echo canceller. The main reason to use the VPMADT032 h/w based solution is because it is immune from any system CPU spikes that might otherwise affect a software-based solution. Never miss a thing.

Sorry about the last post. This one might be easier to read. Actually, I would agree that most of the time h/w is the best option, but for 8 or less channels that you will be using with Digium's TDM800P either choice would work.
