I have a number of SPA525G phones in use, all operated in SIP mode, latest firmware 7.4.3.
Looking through all the menues it appears to me that there's no function to store/save/backup (and later restore) the current configuration of the phone in a file (e.g. name, sip credentials, extensions, etc.). This would especially be useful in case one phone needs to be replaced for whatever reason.
Am I missing something or is this functionality simple not available? If it is missing are there any other options to achive the desired result?
