I have an Aastra 6753i in recovery mode which will not attempt TFTP and returns invalid parameters, have done quite a few we recoveries over the years but never come across this issue.
I have tried this in Chrome, IE and Firefox.
The phone appears to have remembered its previous IP address as it is not connected to any network and has the IP 192.168.0.101.
My TFTP server logs see no attempt of the phone trying to get the firmware file.
Can anyone help?
Regards,
John
