Re: 7965 on 2960S switch unregisters with switchport access vlan

Is there a reason why your data and voice run on the same vlan?  I know you said you got both Cisco and non-cisco but it looks to me you are tagging and untagging traffic here. Not sure of the reprucussions of that since the phones use CDP but I always split my data and voice vlans.
