I have a layer 3 3560X switch where the Avaya IP Office and the Avaya VoIP phones are connected to. I am trying to have the connection between the Avaya IP Office and the Exchange server so that the voicemail can be sent to the users mailbox. My switch is configured with voice vlan for the pbx and the voip phones. The ports are configured as:
switchport access vlan 10
switchport voice vlan 110
voice vlan is 20 and data vlan is 10.
My issue is I cannot ping the IP office from any PCs on my LAN. The PCs are connected through the VoIP phones. When I do the ping 255.255.255.255, I can see its IP address.
