I have two sites connected over an MPLS network. The main telephony (Avaya) switch is in SiteA. The remote SiteB has 2 x 50 user offices (Office1 & Office2) with a local telephony server. This site has Cisco POE switches. I want to have two data VLANs for each of the offices (say VLAN10 & VLAN20). All 100 IP phones should be on the same voice VLAN (say VLAN220). Is this setup correct:
switches for 50 user Office1 have data VLAN 10 and Voice VLAN 220; trunking port has native VLAN10 and allowed VLAN220
switches for 50 user Office2 have data VLAN 20 and Voice VLAN 220; trunking port has native VLAN20 and allowed VLAN220
Thanks, Ned
