Hello,
We have deployed 14 Catalyst 2960XR switches and are finding issues with Unify OpenStage 40 VoIP phones. The interfaces are configured with a voice and access VLAN, and the phones use LLDP successfully to join create a trunk and join the voice VLAN. They pick up an IP address, but cannot communicate on the port.
When a phone is put on to an Access port configured as the voice VLAN the phone works. When we put the phone onto a 3750X switch with the same configuration the phone works using the voice and access VLAN configuration.
Has anyone had this issue before?
