what's the current estimate on PSTN endpoints? 2-3B globally? is that
more/less than the IP/Internet world? I bet it's, at this time, fairly
close to the same number.
Potential references:
<http://www.funtrivia.com/askft/Question25278.html>
thinks the ITU estimated ~33% of 1.4b devices were mobile phones (in 2002)
<http://en.wikipedia.org/wiki/List_of_countries_by_number_of_mobile_phones_in_use>
wikipedia thinks a total mobile phone market is ~4.1b phones with ~60%
global penetration.
<http://en.wikipedia.org/wiki/List_of_countries_by_number_of_telephone_lines_in_use>
number of PSTN lines globally ~= 1.3b
So a total across the wikipedia links says ~5.5b phone devices. That
seems significantly more than IP devices. I did not, obviously, factor
in phones which are also IP devices (your iPhone type thingy)
