We are runnin a MXe and IP phones (5224, 5212, 5215) after installation all worked fine for 3 months. Now for some reason some of the Phones drops from the network. They are using 3com switches. Why does some of the phones drop and after a while they come back agian? It's almost if they are taking turns to drop from the network. PLZ Help

Are there any errors shown in the Maintenance/Software logs?
We have HP network hardware and 5330 phones, after a while I found that phones would just crash and reboot, sometimes during calls or when the device was ringing, unfortunately our solution involved returning the devices to Mitel or replacing the phones from stock.

The MITEL system programming was checked and no system faults or incorrect programming was found.
Due to packet loss on the network some of the IP phones losses connectivity to the MITEL system.
Traffic on the network was referred to as “heavy” on the network for some time while conducting investigation.
We removed the MITEL system from the network while the network was experiencing “downtime”, and even after this was done, the network still experienced “downtime”

I may be entirely off the mark but it sounds like a network storm, perhaps you have a faulty NIC or a scheduled job that transfers a large amount of data over the network?
I would suggest you do implement a separate VLAN for your voice traffic, if only to separate the voice from the data traffic.
Don't forget to implement the Mitel DHCP options on the DHCP server that's in the default VLAN, otherwise the phones won't know to switch VLANs or where to find the MXe.

MiTeLSA, do you have any sort of network monitoring tools?
How big is your network segment? Do you have multiple network switches with redundant links? How about broadcast storms?
In fact using VLANs is the way to go. But you have to implement L2 COS based QoS, otherwise VLANs will not give you any benifits.
BTW is it possible to check CPU load on your network equipment?
