Error updating locale 7961
From the file name, we can understand that this is firmware version 9.1.1, for Cisco 79 SCCP IP phones.
Next, the firmware must be uploaded and unpacked on our CME router.
The create cnf command instructs CME to recreate the XML files that will be used by the IP phone to download all necessary network parameters and force it to check its firmware and begin downloading the new one.
When our IP phone next reboots, it will download the latest firmware installed on the CME router and begin the upgrade process.
This article explains how to reset your Cisco 7945, 79 IP phone to factory defaults, and how to upgrade the firmware to the latest available version.
We also provide necessary information on how to setup a DHCP server on a CME router or Cisco Catalyst switch, to support Cisco IP Phones and provide them with DHCP Option 150 so they know where to find and register with the Call Manager or Call Manager Express server.
here is how I got my Cisco IP Phone 7942 provisioned with Asterisk.
