iphone 4s contact phone numbers not working

iMac - exported contacts from Gmail account to MAC Contacts.

looks good

release security [little snitch] to populate my iCloud

works

iPhone 4s retreives and populates CONTACTS

on phone

some - more than a few - contact phone numbers LOOK correct when viewed on phone.

either tapping on # or requesting from siri ----> error message from Verizon [my carrier]

Entering that number on the keypad........>>> IT WORKS.

NOTES:

Deleted MS Exchange account before problem.

Reset the phone OS 5.01
