Mystery phone number

[Cathyhuns]

Does anyone know what sort of phone number this is?
+442109*91050
My mobile phone has recorded a call from this number and I don't want to ring back in case it's one of the premium rate numbers.

I'm sure if it's important they will ring again!

It's a Hartlepool number ... what's the missing asterisk number?

The number typed is exactly what's shown on my phone, including the asterisk. That's partly what was confusing me.
