This issue started today - when trying to call my friends across town (same area code) I'm having to dial the full code and number. It's happening on two lines from Worthing to Rustington and Worthing Littlehampton and we all share the 01903 area code.
Thanks for your post.
Sorry to hear you are needing to dial the full area code plus number when calling your friend.
We are upgrading our Telephone Network from the traditional socket to a new fibre line through the Hub.
This is being done area by area, It may be the case now that you need to dial the full number, where as before it wasn't.
Are you still on the Traditional Socket for the landline?
