This bothers the crap out of me because a) when I'm signing up as a new customer, the company with whom I am establishing a relationship should be able to verify that I am me and then believe whatever phone number I give them and b) my "VoIP service" is more secure and less well-known than my mobile phone provider, thus reducing the attack surface for those numbers.
