D-Link announced in Taiwan that their line of Broadband devices will be AT&T CallVantage ready. In the DigiTimes report it refers to h.323 and SIP, the later which AT&T is basically moving over to in addition to the current MGCP they are selling.
I think the trend we are seeing has all the Taiwan manfacturers somehow getting into the VoIP game, mostly providing the onramps. I look forward to the day when the endpoint is all we need and eliminate the in home gateway.
