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,
