It's bad enough that we don't have a Call Waiting system that works very well. I had mine taken off as, unlike with BT, there is no way someone phoning you can tell if you are already on the phone as there is no automated voice system telling them you are on another call. If VM don't keep up with current technology surely people are going to start wondering why they bother staying with them

It's a very long and complicated story. Basically, as far as I know, since upgrading to an all digital network BT exclusively use System X and System Y exchanges which support all of the Caller Id., Call Waiting etc. facilities to a common standard. VM/NTL/C&W inherited a mish-mash of equipment from their predecessors much of which can support some or all of these same facilities but not necessarily to the same standard as is used across the BT network. That is why, for example, the star (*) codes for enabling/disabling certain features are different across exchanges and networks. However, in this day and age of software based telephony, I don't understand why this cannot be easily reprogrammed.

Strangely, if you forward a call from VM to a BT or mobile number, the Caller Id., including international numbers if I remember correctly, is forwarded and displayed on the BT or mobile phone (if Caller Id. is enabled). BT on the other had, do not handle inbound or outbound international Caller Id. particularly well causing inbound not to be displayed and outbound to be displayed when the number has been withheld.

With regard to Call Waiting, I believe that VM/NTL/C&W have always said that it does not work with the voicemail facility (although it does on BT).

If anyone can correct or expand on what I have said, please do.
