Good afternoon, I currently have 2 (stacked) 3048P a 4064p and a bunch of Cisco switches (also stacked) I cannot get voice working on the Dell 3048p switches.
Seems like a fairly low level error at the Dell 3048p end, I can ping each stack of switches in turn and the gateway router. All on the voice VLAN IP address range. However I cannot ping any hosts connected on the 3048p. If I set the port to any other VLAN except the voice VLAN it works fine.
But for Voice it doesn’t work, I have tried ACCESS, GENERAL and TRUNK modes and have assigned a static IP address to the host and tried 2 different models of phone. For all intents and purposes traffic just doesn’t get passed to the host.
Has anyone else had this issue before?
