How do I configure a Cisco 7971 to work with trixbox Pro?
trixbox Pro always sets the default nat setting for an extension to be 1, while this should work with pretty much every phone out there, this does not seem to work with the Cisco 7971. No combination of nat settings in the Cisco configuration file seem to be able to get past this like you can on a Cisco 7960. If someone figures out some other setting that will get it to work, please let us know.
