Network setup with VOIP

Ok, new at the VOIP thing. I have a TZ470 with a Cisco C1200 switch. This office will have a server and 18 workstations. Phones 12-15. The goal is to have fiber 1gig / 1gig. They may for a short time have to go with a cable connection 400 meg / 20 meg. My design was to Vlan the phones off from data network and just setup bwm on the voip vlan to make sure we always have some reserved bandwidth for the phones. Am I thinking correct for this. The phone provider will be a cloud voip system. Do I need to do something more for this to work smoothly. Thanks for any advice.

So long as you have some way of distinguishing the VOIP traffic so that you can apply a BWM rule to it then you're good. Voice VLAN is good practice anyway.
My thought was using smartport on the switch we automatically tag all the phones on a voip vlan. Then on the SonicWALL apply bwm on the voip to wan rule. All traffic on that vlan should be phone traffic.
