LAN switches to get smarter about VoIP security

By Phil Hochmuth, NetworkWorld.com, 12/16/05

Avaya and Extreme this spring are planning to address issues involving the authentication of IP phones on a LAN, as well as providing increased DHCP security for Avaya phones, via Extreme switches. The co-developed technology will make Extreme switches the primary enforcement point for IP phone authentication.

Around the second quarter of 2006, Avaya and Extreme will release new IP phone and switch software upgrades that will allow Avaya phones to be discovered by Extreme LAN switches just by plugging the endpoints into the network, according to Richard De Soto, director of converged networking solutions for Extreme. The discovery process will use Link Layer Discovery Protocol, an emerging standard for automated network device mapping and discover. An 802.1x supplicant on the Avaya phones will allow the devices to authenticate to an Extreme LAN switch. This will involve using a third-party RADIUS server to check the phone’s MAC address versus a list of pre-approved addresses.

Can't the competitors already do this with their solutions? Interesting, but incomplete.
