[Asterisk-Users] European Caller ID

[randulo]

Can anyone ell me if they've had experience on the continent with caller 
ID on analog POTS lines?

Here in France, we currently do not have it enabled on any of out lines, 
but I would consider paying for it if I thought * via X100p cards would 
be able to detect it properly.

I know for example that when people are calling us from the US or from 
London CID is not captured by France Télécom, because we have a free 
service here where you can call a number to see if you missed any calls.

Are the technical "specs" of CID different all over? Comments, 
experiences please?
