 |
|
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 |

there is no echo problems on pure VoIP networks.
echo is a common problem when you have changes from analog to digital.
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.
Best regards.

On VoIP echo cancellation is basically: hope that the client is doing AND is doing it well.
In the best case each client uses a knowledge about his hardware (microphone, speaker, distance etc.).

If the clients are not doing the echo cancellation properly, you can always use a centralized echo cancellation software for VoIP networks.

Does anyone have any experience with PBXMate and the quality of the software? Does it cancel echo properly?
Can someone also give me an price indication of the software? I can’t find it on their website.
