It took me another 2 days of trying randomly at various times of the day to add the device before it finally worked. It seems to me, with as often as Polycom has been taking down their servers for upgrades, they would have figured out why it isn't working properly and fixed the issue.
Also, has anyone noticed that a person can no longer call Obi. The link is there on the OBiTalk page after logging in but when the person clicks on the "Call OBi" link, it only brings up a dialer and allows the person to call a speed dial or optionally open a dial pad and manually enter a number but none of it appears to be working.
