My compnay used to use a wonderful product called HearMe VOIP using SIP. By far it was the best VOIP solution that was available in the market back in 1998 and I believe still is, unfortunatly the company went bust and sold thier assets to GameSpy.
We use a company called TelcoPoint to provide us with VOIP (Which uses HearMe’s technology.
Right now I am trying to search for a solution that will allow me to do PC-PC VOIP,not really concerned about using VOIP telephones.
Would anybody have any solutions in mind? http://www.vovida.org has some nice open source stuff but nobody is really using it on a large scale.
