The phone uses DHCP to get its IP address.  In the phone's server 
params, I enter the IP address of the tftp server.  Without the 
"next-server" entry in the DHCP configs, the phone says it cannot find 
the boot server (and uses the previous configuration).  However, when 
"next-server" in DHCP is set with the tftp IP, the phone loads its 
configuration from tftp and boots normally.

I'd like to not have to set the tftp address in DHCP, because I don't 
always have access to the DHCP server.  Is there someway to tell the 
phone to override the DHCP server setting?  Is there something I'm 
missing with the phone's network config?

Thanks
