I am looking for your opinion on setting up an Epygi M8L. As this is a new installation I am wondering if it is better to put the PBX on a DMZ or on a VLAN. We are using a Sonicwall NSA 240 and I have a managed switch available. I was thinking that putting the PBX on the VLAN with the phones connected to the WAN side of the Epygi would make it a little easier to manage the overall. However, if I put the Epygi on a DMZ in Transparent Mode the phones would be on the LAN side of the Epygi and I can take advantage of the auto provisioning.

Your thoughts are appreciated.
