Bizzare Vodafone CLI

I've noticed over the last week or so that the CLI on my mobile is dropping 1 or 2 digits off the end when receiving calls. This is also happening with other mobiles in the office which are Voda too, but we can't get it to happen with any other provider.

This is not just calls coming from the office, but from all over the UK, mixture of land and mobile numbers.

I suspect that after their recent spate of completely screwing up Mobile Number Portability, they're having a bit of grief to get that sorted and they've bodged together a change in number lookup protocol.

The numbers you dial on the phone, by the time they reach the core signalling network have your number or IMSI attached, a VPLMN code, restriction codes and allsorts added... - All a provider needs to do is forget, or misconfigure one level of singalling and calls will connect to the wrong place, if at all, or drop CLI.

It's all too complicated for me, so I just stick to authorising replacements for blatently faulty phones that Customer Services seem to insist we look at.
