Hi, Here is the recommended way for configuring both phone and data. [URL]   Data ends up in the untagged native VLAN and voice in a tagged VLAN.
I am in the process of implementing a VoIP system and am struggling with the network config. I have a mixed environment of 62xx series switches and 28xx series switches. I have created a VLAN for voice and am using the default VLAN for data. VLAN routing on the l3 switch is working fine. I can ping between subnets with no problems. IP helper is working, as IP phones will get an address on the data subnet, then reboot and use vlan tag to get IP on the voice subnet from any port on any switch. But if I set the pvid on any port to the voice vlan, Windows machines will still successfully get DHCP on the voice vlan, but IP phones will not, they will only get an address if going through the data subnet first. My voice switches also lose communication entirely, when set statically with a voice subnet address and connected to a port with voice vlan pvid. Going through the data subnet to get an address is no big deal, but not being able to put my voice switches on the voice subnet is a problem. I will freely admit that I only sort of know what I'm doing. Any assistance or advice would be greatly appreciated.
DHCP over 62xx switches and 28xx switches
