This will avoid potential issues in environments with more than one CompletePBX systems, such as lab environment. Once the phone’s MAC ID is registered in EPM, the phone will get an automatic reply from SIP Plug-and-Play.

-d -enable debug messages to be send to the system journal. You can run the following command in order to see the messages:
journalctl [-f] [-u epmpnp] -a
