I am trying to have a 7970 register across a different subnet on a CME. It will register if I set the source-address to the external port of the CME but then that causes the other phones connected to the i.nternal ports to not register or not register correctly. i.e. "Nonce tree obsolete". How do you get the phones to register correctly?
I have attached my config

Why SIP to begin with ?
Less features, more bugs.

Convert it to sccp and you will not have any issue.

Also do you have suggestions for getting through NAT at a remote
site? I dont think STUN is supportd on Cisco phones.
