CID seems odd to me. When I first visit Vpanel CID, the only number shown was the 2nd line/VN, which was not my current CID to my knowledge. In fact CID had become my registered first name plus the first 6 characters of my last name as CNAME I guess, and the primary number for the account (strange at best). I clicked on the displayed 2nd line CID and then the drop down listed both numbers. I clicked on my primary number and my CID became my primary number for CNAME as well as for the CNUM portions. The Vpanel display then reverted to the original display with the 2nd line number number listed and with no alternative available in the list.
