Download the "Framework Tool" binary and put in /usr/bin on your iPhone. Make sure to chmod 755 the "Framework" binary or else it might not execute. Then run "Framework AppSupport decompo*******Number xyz vn" on your iPhone where "xyz" is the phone number (containing only "+" and "0" through "9" characters) and check the output. Instead of the "decompo*******Number" function you could also try the CPPhoneNumbersEqual or CPPhoneNumbersEqualStrict functions to check if two different phone number strings are equal or not.
