Just a thought. If you do lock down your option 150 that may restrict any IP speakers you may introduce at a later point if you do not have any currently. I am thinking of emergency broadcast services that may come to play. I would be interested in the VCI list as well but am thinking of how it may impact our current and future IP speakers.

We're trying to lock down our DHCP servers to only hand out TFTP server details via option 150 to classes of devices we expect to see on our network. (Yes, I know we could/should lock it down to only supply option 150 to devices on the voice vlan but, alas, I can't always guarantee our devices are on the "correct" vlan) --- /-Gary Parker----------------------------------f--\ | Unified Communications Service Manager | n Loughborough University IT Services | | Tel: +441509635635 Mob: +447989172258 o | http://delphium.lboro.ac.uk/pubkey.txt | \r----------------------------------------------d-/ _______________________________________________ cisco-voip mailing list cisco-voip@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-voip
