The unfortunate thing here is there is a network disruption caused by the network not set up properly to support VoIP or a problem on the network.
The file it's trying to pull from the phone system is very small, and it uses TFTP. If there's a disruption in the download, it will cause the set to reboot.

You need to contact your system admin or your telephone system vendor and your network admin/vendor to have it resolved.

This process may vary depending on what system you are using and what version but here is how you get into the phone:
1)Hold down the 2 volume keys at the same time and plug the network cable back in all the while holding down the 2 volume keys.

1)When you see "NETWORK PARAMETERS?" release the volume keys.
    2)Press the <*> key for YES
    3)When you see "VIEW CURRENT VALUES?" press the <#> key for No
    4)When you see "VIEW DHCP VALUES?" press the <#> key for No
    5)When you see "VIEW STATIC VALUES? press the <#> key for No
    6)When you see "VIEW PERSIST. DATA? Press the <#> key for No
    7)When you see "MODIFY STATIC VALUE?" press the <*> key for Yes

    Again this is for a more up to date version of Mitel firmware. If you see something different let me know.

    Good Luck

Poor sound quality

IP phones compress analog data to avoid excess bandwidth. When calls are placed long distances this becomes really noticeable.

Mitel phone only operating in 1 direction

Does the phone have a router/firewall/Layer3 data switch between the phone and the controller? If yes I suspect you have blocked UDP IP ports. Here is a wiki on TCP and UDP ports. ports you need open to the controller are specific to your system model. The 5312 phone works on different controllers. Please list the controller type you have. Good Luck.

Mitel 5550 Console cannot obtain ip address.

Follow the proper boot-up sequence in the manual, and verify the PC boots up on the native lan first.
