Tonight I was talking on the telephone with Bob D. (Cincinnati to Columbus) using my Junction Networks SIP service with my Aastra (beta) Response Point system. Bob said that the call was crystal clear and we wondered what would happen if there were a little more of a load on the line. So, I brought up download.microsoft.com and downloaded Windows Server 2003 Service Pack 2 - about 375 meg. I've got Time Warner's Telecommuter ISP service. My download started out at about 900 KB and trended down to about 600 KB. During the download both Bob and I continued to have a crystal clear, solid sounding conversation.
