We have a 3925 intergrated voice router that prompts this error cmapp_sccp_tftp_download_file: Unable to get configuration file size tftp://x.x.x.x/SKIGxxxxxx.cnf.xml, rc=-2
It gives the IP to our call manager then a mac address of analog gatway and extension pertaining to cnf.xml. The error runs when the router is connected to the network and also when it is not connected to the network. I have looked in the Cisco bug toolkit did not find a bug that was related to the issue. I check the tftp in the call manager there is no file of that type which there should not be. We have 3925s voice routers already registered to the call manager. Voice router information below:
