My husband called me today using HIS phone. The caller ID said 213-291-1900, which is obviously not his phone number. He called back 3 times and all 3 times it gave that number. But when I called it, it gave a fast busy signal.
STRANGE! My husband is calling my Alltel phone from his Sprint phone and this number is showing up. Got the fast busy when I called back also... someone suggested power cycling your (both) phones.
