Given that we're talking about cell phones, it seems completely likely. Cell phones present the dialed number as a block, so there's no ambiguity between 911 and 911XXXXX. I don't know whether UK cell carriers map 911 to 112, but there's no technical reason they can't do so.
If people expect 911 to work on mobile phones, they will also expect it to work on the PSTN. <rant> And why should the UK change its numbering system just because a few dumb Yanks who can't be bothered to learn local customs? Does 999 get through to the emergency services in the NANP? Does 112 work on non-GSM phones? How about Australia's 000? </rant>
I agree that for VoIP using normal phones through adapters, 911 in the UK won't work.
ATAs usually collect digits to send as a block as well, either with the user explicitly dialling # after the number, or implicitly after a timeout. At least that's what I see with Cisco ATA-186, 7940 and 7960 and the Sipura 2000 I've tested. -- It can't go any lower? Last time I checked, the minimum value of a traded security is $0.00. - H.
