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?

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.
