DHCP string for IPT

Hi, Any advise on how to get a DHCP option code 128 string passed to an IP phone from a 2821 router acting as a DHCP server. The router is issuing DHCP addresses on the data vlan as expected - the phone is then expecting this string to be passed down; any examples appreciated.Thanks, Ned

On a 2821 router I have DHCP enabled for two VLANs - data & voice. I need to pass on a "DHCP oprion 128" string to set up the IP phones.Has anyone an example of how this is achieved on an IOS router? Thanks,Ned
