Does anyone have experience of the Echo Cancellation abilities of the Jabber Video for Telepresence client?

Hi All,

In the Cisco blurb for the Jabber Video Telepresence client (, it sates that the client incorporates:

48-kHz wideband audio subsystem with compliance-grade, adaptive, acoustic echo cancellation

Sounds pretty cool (no pun intended). But I wonder what experience users might have of this in practice with an open mic and room speakers? Of course, audio is still, by far, the most important feature of videoconferencing - you certainly can continue a video conference with no video, but with no or poor audio, things become impossible.

We have had client that have tried to use the Conference Me client with open mic and PC speakers but, but it is next to useless in this scenario. Of course, these are both designed as personal videoconferencing solutions and really it would be beneficial to empty some kind of headset, thereby eliminating the need to echo cancellation entirely. But, unfortunately, we have the need to see if we can get small temporary groups of users together in a room without running to the cost of even an entry level CODEC.

To make matters more complex, the users want to use a wireless mic (such as the RevoLab "Solo Single                 Channel Wireless Microphone System", or possibly the "HD Single/Dual Channel Wireless Microphone System" to be used as the mic inputs. Whilst these are still not inexpensive items, there are more affordable than an SX20 package.

We have used Jabber for some management types with the Polycom C100 Communicator with good results, but again this is a little to 'personal' for this intended use.

It maybe we are on a hiding to nothing, but still might be worth a shot.
