Thanks for your reply. I do use my Google Mail / Voice account for multiple things and it stays open. Following earlier advice I created another Google Mail account, pointed all the incoming mail from it to my main account, then transferred the Voice account to the new GM account. There is a good write-up on this if you Google "Transfer Google Voice to a new account". I changed my OBi setup for SP1 to the new Gmail account, it verified and, voila, the phones all ring. I feel much safer that my OBi account does not contain the name and password of my Google documents, etc. I have been in this business too long to ignore one of the basic rules. DO NOT PUT ALL YOURS EGGS IN ONE BASKET! I think that I will be creating more email accounts to manage the various internet assets that I own.
