Hello fellow BB users. I'm new to BB, this is my first one. I just got the 7520. I got it through my job. But upon getting it, I can't recieve incoming calls via phone number. When calling the number, the BB doesn't ring, vib or show anything on the screen. But the phone that I call from rings like normal and the voicemail comes on. I can call out and DC in and out. Anyone got any ideas on what the problem is?
