Thanks. Some of the problem is pilot error. If I click on [Expand], I can get to the second unit. However, when the second unit is connected, it kills Line 1 (VOIPo) on the first unit. If I disconnect the second unit, Line 1 on the first one reconnects.
Is it correct that the second Obi200 has to use a port other than 5060? As directed in another post, I changed it to 6060 by logging into the Obi200. When I go through the SP1 setup on the second unit, I enter 6060 as the port. However, when I look at the settings directly in the second unit, the port has changed back to 5060. It's not clear to me what I should be doing. For what it's worth, my Google Voice number on the second unit is working just fine. The second VOIPo number (Line 1 on the second unit) will not connect to the VOIPo server. I'm sure the user name, password, and server details are correct.
