[cisco-voip] 8800 w/ USB External Sound Card

[Pawlowski, Adam]

We've used things like this from dynametric in the past as well which work with just about any phone:

$95 seems a bit much for what's probably a transformer in the box, but, similar things are available from sandman or elsewhere at a lesser price.

One interesting use of these is that the phone does a pretty good job generating an RTP audio stream that you can direct at another device unicast or a multicast address, and just use it as an encoder, to feed to other phones. I never had much luck with VLC doing this reliably, but plug a white noise source into the phone, and then allow your users to turn it on and off with a little XML app. Could be a killer app for those sweet open office floor plans.

Mic test works too!

Unfortunately, no echo cancellation. But at least there's no feedback loop. Granted, I had the microphone right beside the speaker for worst case scenario. I'm guessing with proper placement, it should work ok. Worse comes to worst, mute phone while other side talks.

Looks like it works!

Tested headset port on USB device. Will try rca ports when I find my patch cords.

Then I will see if echo cancellation works.

Anyone try a driverless USB External sound card on the 8800s? Something like:
