What can I do to check why our company phone keeps going out and we are losing calls. We keep getting a message that system is upgrading.

SOURCE: Night Service and Diver All Call to Voice Mail

make sure the call rerouting always is setup and points to the vm huntgroup, then check the call rerouting assignment points the answer point extn number to the relevant always alternative in night1 and night2 mode

ie; always alternative 10 set all to Reroute and supply vm huntgroup number then program call rerouting assignment for extn during night1 and 2 to 10.

let me know if this resolves the issue if not it could be a number of other timer related / vm configuration / call routing problems which might require a more indepth investigation

Make sure that it is a Dual Mode 5220. If it is you can use it as a SIP extension. It wiill say it on the back of the Mitel phone next to the 5220.
If it is a dual mode phone you can purchase a sip trunk from a provider and then would be able to use the phone.
When you boot up the phone hold the blue super key while the phone boots, hit the no softkey till you get to phone mode. Hit yes it will allow you to change the phone from minet to sip. This should get you started in the right direction.

Your phone is in Do-Not-Disturb. Press the blue superkey. Press No until you see DND or Do-Not Disturb and press yes... press Turn off.
