I completed two intalls last week using 1.6, Aastra 6731i IP phones and VoIP for the voice. I am just curious if this has happened to anyone else as of yet. I ran the aastra xml scripts and set up the phones perfectly they found the server and asked for the extension and password right away and configured using the demo.prf files I modified for the 8 buttons. About one week later the customers called saying their park button and voicemail buttons did not work, so I went there to find out the phones reverted back to factory default keeping their authentication such as sip credentials etc, but all of the xml was wiped away. It wasnt a big deal to do it the old way and just hardcode it in there but I am really curious as how the xml got dissassociated with the phones. I erased there local config file and ran setup-aastra-xml again and it happened again after a couple of restarts. I have multiple installs using 1.3 and xml and this has never happened to me. Any info is much appreciated thanks.
