Office phones.

I have two phones on my desk. One is white. One is grey.

The grey one is a fancy new IP phone. The old white one is not.

Last week the white phone worked for everything I need a phone to do and the grey one did not.
Today the grey phone works, and the white one does not.

They both have different phone numbers. The number that people call me on is the one that doesn’t work.

I’ve tried calling IT about it, but I can’t call them from either phone.
