I have setup:

  • VLAN 1 and subnet for data

  • VLAN 100 and subnet for voice

  • IP phones get their IP via DHCP on the subnet

  • all other IP devices get their IP on subnet

I am using "Cisco Unity Connection" for auto-attendant and voicemail.

Question 1: In which subnet "Cisco Unity Connection" server should be put?

subnet or subnet

Question 2: The "Cisco Unity Connection" server VM is running inside a Vmware ESXi host. In which subnet Vmware ESXi host should be put?

subnet or subnet

I am asking these questions with QoS in mind, with voice traffic prioritization perspective.

Thank you for your help.

I'll suggest using a third vlan for infrastructure.

Depending on what your are using for routing between vlan, this may help you to protect your infrastructure (access list, firewalling), enable QoS on both "user" subnets (voice and data) aso.

Cisco Unity Connection - 100.0 - You can use DHCP.

ESXi - 1.0
