Following are the issues with phone number field.
1. Any alphabetical character is accepted in phone number field.
2. Phone number prefixed with '+' sign considered as new number.
e.g. 919922992299 & +919922992299 are considered as different numbers.
So check which disallows user from entering / using same number fails in this case.

Here is the patch that validated phone number. Also I've checked in module ( 7.x-1.x ) and found out phone number prefixed with '+' sign does considered as same number not as a new number. Please review.
Thanks!
