Hi Oliver341,
As I mentioned it depends on different models. Some folks don't do the volume of calls (maybe just used for a data line) so why pay for things you don't need? Most the options you mention via BT are included, but via a bundle or feature a customer is paying for, so included yep, but are indirectly being charged. BT line rental with evening/weekend plan comes to £17.75 (BT charges also go up on Jan 5th, ours, and I presume may other companies, are not).
For reference (and data from a few hundred phone lines) only 9% take Caller ID and 4% take voicemail (likely because they have answerphones with it built in).
I disagree on call charges....our rates are very competitive for a WLR3 based solution. Likewise, no 12 or 18 month contracts.
