Yes, good point.

Andy,
Thanks for taking the time to author such a comprehensive reply. Much
appreciated.
If I go for the ATA and an analogue phone, or digium card + FXS + analogue
(to begin with) would this limit the availability of features? I'm not sure
how featureful your average VOIP phone (like a grandstream) is compared
to analogue phones of the same price.
My last phone just died. I bought it for £15 about 5 years ago, and the only
feature it had was redial! I don't want but an ATA and a new anaolgue phone
only to regret the loss of features. Maybe I'm just getting too excited
about the possibilities - after all, I hardly ever used redial...
Thanks,
Ben.
