I'm attempting to configure the Call Manager Express 4.1 on a 2901 router. I have 2 Cisco IP Phone 7961G's. My connection to the network backbone is via a Catalyst 3560-X-Series switch hosting the local DHCP and NAT'ing to the network backbone. My question is concerning VLAN's and DHCP hosting. Will I have better success with the router hosting the local DHCP and/or will creating a voice-VLAN on the designated ports for the phones back to the dedicated port on the router?
