DHCP additional options

[kevmullet]

Hello,

I have a scenario where I have a set of IP phones that need to receive a certain option from DHCP to connect correctly to the phone system.

I am wanting to use a Cisco ASA 5505 to provide DHCP, which is fine, but how do I add additional options to the DHCP scope.

Thanks

dhcp option

 ip [ip addr] [ip addr] ...
dhcp option [code] ascii [text]
dhcp option [code] hex [value]
