[asterisk-users] Echo Cancellation on VoIP networks
Hello, I'm new to Echo Cancellation and I was wondering how it is handled/works on pure VoIP networks using Asterisk? I did some research on the internet about EC on VoIP networks, but I can't really put a grasp on it. We currently have some Echo Cancellation chips on our Digium cards, but are planning to move to a full VoIP network based on Asterisk. So no more ISDN in the voice path. Does Asterisk have any pre-installed Echo Cancellation software? Which hardware cards are recommended for doing echo cancellation on VoIP networks? I hope someone could point me into the right direction. Regards, Grant -------------- next part -------------- An HTML attachment was scrubbed...

The only echo problem you will have is when you call another network who has analog circuits with wrong configuration or poor hardware. But you can't solve it.
