Did you remove the power cord from the OBi110, wait a few seconds, and plug it back in?
When you dial * * * 1 from a phone connected to the device, does it give you an IP address and can you browse to that IP address and log into the device (remember that if you did a factory reset it will have reset the password back to the default). Did it say that DHCP is enabled?
If those all seem good it MAY be a temporary server issue. I'd send an e-mail to
support@obihai.com and give them your OBiTALK number and see what they say. If it says that DHCP is disabled (which it should not be if you did a factory reset) or if it gives you an IP address that's not in a vaild range for your network, then you may have some other issue having to do with network connectivity.
