Mitel's SIP firmware site at http://sipdnld.mitel.com/ has gone offline without notice. SIP firmware must be obtained through a Mitel reseller. May also be available for download via BitTorrent or on http://drop.io/mitel5224. The latest firmware (8.0.0.4) is available here: http://www.mediafire.com/?utkxeyzuz71m9ag
If you are running Rel 3 software, you will need to upgrade to Rel 4 prior to going to 5.0.0.21. It is strongly recommended not to upgrade through the GUI. Only the Boot (Set) upgrade should be performed if you are running software lower than 6.0.0.19.
Although account settings tend to be saved between firmware upgrades, it is recommended that a factory reset is performed at the end of the process. Phones not reset might suffer from miscellaneous issues, such as random SIP re/registration failures and phone setup Web pages not showing.
For all SIP Phone types running any software previous to Rel 7.2, this includes Rel 3.0, Rel 3.1, Rel 4.0, Rel 5.0 MUST upgrade to Rel 5.0.0.21 prior to upgrading to Rel 7.2.
Rel 5.0.0.21 MINIMUM is required as a stepping point up to Rel 7.2. Any other method of upgrade could result in corrupted Flash Memory on the SIP Phone resulting in a permanently dead phone.
When upgrading to Rel 7.2 from any previous software through the Rel 5.0.0.21, not all SIP Phone Feature/Parameters are carried forward. ...
