Hi Leanne, thanks so much for your quick response. It is my works mobile. On days off I will forward my phone to the office mobile so that calls can be answered by colleagues in my absence. I have been doing this for months with no issue. Today I have been working from home and tried to take my mobile off divert to the office and I get the same error message and it won't let me take the phone off divert. Sometimes it shows the number it's diverted to and other times it doesn't! I have taken the sim out, cleaned it, I have left the phone off for a time. I have turned WiFi off and tried it and then on again, I have checked for any phone updates and it was recently updated. I am at a loss! All of my calls are diverted to the office phone! I can make outgoing calls fine, just can't get any incoming.
