Why does that make it unimportant. SS7 in the UK has only minor 
differences, which could be allowed for. Of course, that means a special 
UK approval, and EU approval won't work for the UK.

Don't other operators in the UK use the standard SS7 protocol? I thought 
it was just BT that would not fall into line. I haven't worked there for 
12 years.
