Thank you for your responses. I also appreciate your opinions as well. Allow me to break this down, more. I have a data center. In this data center, I have a server cluster. This server cluster is behind a Meraki MX that serves as the cluster's gateway to the internet and VPN concentrator for "branch" locations to access via site-to-site VPN connections. My "branch" locations have 2 VLAN segregated subnets, one for their corporate network and another for their voice network. These VLANs are configured to not route between each other (no inter-vlan routing). In my data center cluster, I have 2 VLAN segregated subnets; one for their corporate resources and another for their voice resources (PBX). These VLANs are configured to not route between each other (no inter-vlan routing). I want to create 2 different tunnels. One to keep voice related traffic specific to the voice networks between sites and the other for corporate related traffic specific to corporate related networks between sites. I don't want to intermingle that traffic on 1 tunnel. The diagram below is a bit more descriptive.
