We are getting ready to roll out VoIP using all Cisco equipment. Some office only have 1 data run. We currently use Port-Security to prevent unauthorized devices. Since we will have seperate voice and data vlans, we would have to trunk on that port. Port security is not applicable for trunk ports. We are not ready to roll out 802.1x port authentication. are there any options on the phones to restrict what PCs can be plugged into it's switchports?
