Dear NFON customers,
we would like to inform you that the following Aastra / Mitel devices are EOL.
These devices are no longer supported by Aastra / Mitel.
- Aastra 6753 manufacturer EOL: 07/2015
- Aastra 6755 manufacturer EOL: 07/2015
- Aastra 6757 manufacturer EOL: 07/2015
A flawless functionality can only be guaranteed with a current firmware.
Existing phones are updated automatically.
Since there will be no more updates from Aastra / Mitel after the EOL, compatibility cannot be guaranteed.
Support for existing customers will continue until the end of 2019.
Kind regards,
the NFON team
