There are no market studies on how people use phones, says Manuel Wexler, CopperCom CTO. So one can argue that "not all calls are the same," he says. "You might want to be paid for taking a telemarketing call." In other cases, you just want to block some calls. Others are really important. "So maybe all phone calls aren't the same," Wexler says. "I haven't seen a study where people attach value to a minute of talking."
Skype calling arguably is used differently than mobile, inbound differently from outbound, IM differently from SMS, video differently from voice-only, voice-only differently from multimedia sessions. Users have different preferences for one mail box or multiple mailboxes, one device or several, soft client versus ATA-based calling.
Cable sells voice as part of a bundle. Vonage customers probably are different, he maintains. Vonage sells VoIP. Cable sells voice, but not VoIP. "Right now telcos sell two sizes of voice: consumer and enterprise," he says. There's "not much segmentation."
