Okay do you know the number for your company? Call them and tell them the number for the roaming list update/ activation number keeps dialing its self and they'll trouble-shoot your phone right there from the desk!
There is nothing wrong with YOUR phone. Its just a glitch in the system with those phones in general. Hopefully it will get fixed soon.
Been seeing many people posting about it. I feel bad for them,
Oh well. Good Luck!
