Every time someone leaves a voice message:
1) The phone does not beep to let me know a message has arrived.
2) The phone's blue light does not come on indicating I have a new voice message.
3) A status message appears when I drag down saying that something went wrong with voice mail and "error code 9007".
I have cleared the cache and power-cycled the phone. Does not help.
Please ask the programmers of the software what "error code 9007" means. Someone had to write the program to return that specific code and should know what 9007 means.
