What is interesting is that voice over IP is becoming just something to add on to broadband. Several ISPs or pure-play VoIP operators were busy signing up people to flat rate telephony. There was also the faint rumblings of voice over WLAN for consumers. In fact, VoIP/WLAN could be sold and designed just like cordless phones: a base station that plugs into the wall (in reality an ADSL router and wireless node) and a cordless (wi-fi) handset. Looking further, video over IP (and video over WLAN) are becoming a not-too-distant commercial reality.
