Change sip phone ip

I have a new phone that is going to be at a London office that will be NAT’d back to my asterisk network and need to change the dhcp address etc. on my 7960. How do I do that manually or get the phone to pickup a different default sip.cnf file?


I don’t believe Cisco phones support NAT.

dhcp is a question of configure the DHCP server for the broadcast area containing the phone.
