EuroVoiP has a note on the Summit that James Enck attended and commented on. I like EuroVoIP summary though on how BT looks at the glass half full, rather than being half empty.
Eventually all the PTT's and RBOC's will be on VoIP. Why? They will have amortized their hardware and physical plant investments in circuit switched hardware legacy systems and will now be able to justify the new direction.
CNET has more on the story and even quotes our ex-pat pal James.
