BellSouth seems to have a fine appreciation for VoIP-over-Wireless. Speaking at a Light Reading conference today, Joan Kratz, VP of business marketing at BellSouth Corp. said that BLS is looking to exploit VOIP over wireless wide-area networks (WANs). “We are actually doing a real test today in the labs with a real customer. We’re in a beta version of that,” she says. “This involves an IP PBX and an IP phone that lets the customer roam on and off the GSM network. You will have the capability to read your voicemail, to hear your email, and to get access from whatever that device might be, either wireless or wireline,” she says.
