Do admissions offices routinely contact the applicant's recommenders? If they do, is it usually by phone or are they more likely to use email?
One of my LORs is from my employer, who is often away from the office. It just occurred to me today that if admissions offices do make use of the phone number from the LOR form, then I should have put his cell number instead of the office number.
Edit: Hoping to either find some peace of mind, or some idea of how badly I've screwed things, depending on what the answer is
