I was wondering when the IP soft phone will be coming out and just how good a quality it is? I currently using voice port enabled 1750's and they
work fabulously. I can call the cisco from netmeeting, but it seems even with the best computer, sound card and microphone technology there is some low level garble that spoils the sound quality very badly. Because this is not present when recording from the mic and playing it back, I'm assuming that it's software (Netmeeting) induced. This being the case there's a chance that the cisco software could possibly be as good as their hardware solution. Does anyone know if this is the case? Is there a beta testing program and/or download trial software available?
The Cisco IP SoftPhone will be available for download in the Software Center sometime [planned] in the next week or so. It will be recommended/required that you be running at least version Cisco CallManager 3.0(6) or better on the server, which should be released at the same time or before SoftPhone.
As far as voice quality, some of the key things that have an effect on this with PC-based clients are: codec used (with SoftPhone, either G.711 or G.729a), properly configured network between PC client and the other end of the audio stream including any necessary QoS configurations, and microphone/speakers used. I have had the best results with the new Plantronics PC headsets that came out a couple of months ago. They come in monaural, binaural, or full-coverage [beefy] binaural. Purchase online or at your local PC / electronics store.
The Cisco IP SoftPhone uses the TAPI interface to make calls through the Cisco CallManager. Although such a configuration would be supported, it may be possible to use the SoftPhone where the TSP on the client machine points to some application on the network other than the CallManager.
Note that the Cisco IP SoftPhone is H.323 compliant only in that the Cisco CallManager is H.323 compliant, as it handles H.323 calls for the TAPI endpoint as a proxy.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
