The main problem for me is to flash this last firmware.
I try directly from the Web UI from the aastra, by FTP, HTTP and TFTP, but it doesn't work.
I'm using the TFTP server from the SME sark, and put the 57i.st file on /tftpboot/
Reboot the phone and follow TFTP session with Wireshark, but nothing action on UDP 69. I try after boot on Web UI, but the phone anwser me, that the file is not found...
I try with FTP session, give user and PWD, and put the 57i.st file at root of FTP session.
I try with HTTP session, give user and PWD, and put the 57i.st file at root of HTTP site.
Same anwser
