IP Office Essential Edition R11.0.4.0.3(3), 3730 DECT phones. This is the second time I've seen this in the last few months, and I'm hoping to find an answer. This is a brand new system that has twelve 3730 phones on it. Non-provisioned simple install that has been used for almost fifty sites. What happens is that once all the 3730s are created, assigned, and subscribed, test calls will only work to the first 3730 configured on the system. All other 3730s ring busy and give a wave-off tone when trying to dial them. The number of licenses is correct and the license file is showing as valid, and all phones show as subscribed on the Master base station/access point. Any ideas as to what could be causing only the first phone to work normally?
