Re: lock down data on a voice network

You can do the following to help with physical security:

disable switchport on the phones

shutdown all ports on the switch not in use by a phone or uplink

You can create an ACL on the router that blocks all traffic on the voice vlan except for RTP and signaling. This will block any traffic that is generated
by the workstation.

In addition to Mr. Watkins suggestions you might want to consider port security.
