Prepend call notification with 'likely to be ...' in the case of 
anything but an exact match.

I think it's best to keep it realistic, in that we can only match what 
we know. Unless you can harvest a country code from the network 
registration to figure out the prefix of numbers displayed in a 'local' 

I'm on the Vodafone network too and store all my numbers in 
international, so don't actually have the problem but I've seen it on 
plenty of other providers.

I guess the only assumption you could really make is that anything 
without a prefix is local ... and therefore should be matched to the 
prefix of the registered network ... or user configurable? A basic 
configurable regex maybe ... so as not to exclude people who get odd 
local prefixes ... though there's probably a limited set that get 
applied globally.
