Applies to VoipNow 3.5!
There are situations when you need to switch to distributed setup. And when you do, most likely you have to remove specific nodes from the Infrastructure Controller. That's when you notice there is no way to remove them.
It is assumed that you are using a CentOS 6.x, CentOS 7.x and you have the latest version of VoipNow 3.5 installed.
As of VoipNow 3.5, deleting roles comes with several restrictions. To be able to delete a role, you need to have less than 3 extensions and no channel assigned to the specific SIP node.
These restrictions are due to multiple backend references between the extension and specific nodes.
To make sure that nodes are properly added, we recommend that you contact the Professional Services them using the help.4psa.com portal.
