Hello cwallace-ena,
Welcome to the Polycom Community.
Just wanted to let you know that there's a KB Article containing the list of Trusted IP Addresses, Hosts, and associated Ports required on a firewall for OBi ATA's. The Article number is: 37792.
A common reason why OBi ATA's show up as "Unmanaged" in PDMS-SP, is that a device was "Claimed" after it was connected online. Our devices, by design, will ask where they are claimed, and then go through the Zero-Touch customization process. Once the device’s association to the PDMS-SP account is established, it will no longer ask our Cloud where it’s claimed anymore. . This means that if you get the device claimed after this ZT process, it will never ask the question if it belongs to ENA. Hence, the OBiTALK tether that the device has is not with ENA, therefore in your web portal it would say “Unmanaged.” What you can do is dial an IVR sequence of codes on the ATA to make it ask that “where do I belong” question again: ***, 0, 8888#, 1, 1#, 1
