* Telephone numbers are meaningless and unmemorable
* Telephone numbers have an undesirable operation that can be performed 
on them: they can be used to make that thing in my pocket buzz and ring.
* Phone numbers are not permanently attached to a person. While I've 
successfully maintained the same phone number for my entire 
mobile-phone-using life so far, I think I'm the only person I know who 
has managed that.

If you wish to use a phone call or SMS message as a prerequisite for 
signing up — in similar vein to email verification — then fine, but I 
really don't like the idea of using telephone numbers as identifiers.
