Hmm - that does sound interesting. I like Bob's suggestion that random VoIP
clients can be treated as house extensions which is exactly the model I'm
It might also be an idea to buy 2 new numbers - one for "work" and one for
home - I'm always giving out my mobile to random reps then having to decide
who to ignore on a day off.
No-NAT at home is easy (have lots of IPs) but of course mobile in 3G/WIFI
mode is most likely to be on a natted connection, or heavily firewalled.
Reckon I should buy a number and start experimenting! My servers at home are
not up 100% of the time (more like down 2 days in a year) but A&A's fallback
option could be used to fall back to my POTS number, so that should be OK.
