UK dialling code shown incorrectly
Hi
I have a number of contacts in the Waltham Cross / Waltham Abbey / Epping area (the "Lee Valley" exchange, based in Waltham Cross) which is 01992 xxx xxx.
When they call me, the caller ID on my iphone shows the location as St Albans. However, St Albans is 01727 xxx xxx. And the other side of Hertfordshire from the Lee Valley.
If I get a call from London (020) or Bristol (0117) then it shows correctly.
How can I fix this?
Thanks
