Fanvil FDPS and FDMCS

We currently use Yealink and they Yealink YMCS platform to create a zero touch experience with our customers and have that system perfectly fine-tuned. But with the introduction of the Fanvile devices, we were wanting to test them and see if we can create the same experience with these devices as well, so we can offer our customers a variety of devices to choose from, but with the same enduser experience. We also have access to Grandstream’s GDMS system and I think we have that down, but we’re still testing it too. If anyone has any experience with Fanvil primarily, or the Grandstream system, I would love some instructions as Fanvil’s manual isn’t very description friendly, nor does it go into any details. Thank you.
