One of our customers having problem with mitel controller CXi release is 4.1. All phones are 5330 and all of them stays on continuing boot up. It receives IP from the controller. I havent seen this problem before. Then we have to shutdown system and reboot. This thing works sometimes and sometimes it doesnt work. All ip phones are connected to layer 2 switch of the controller. Any help?? Thank you.

What is handing out DHCP? Your PBX or another server?
Secondly, if you have your 3300 handing out DHCP, are you handing out DHCP from another server on your data vlan? If yes, is the data switch port connected to it an "access port" or a "trunk port" or using tagging? If it's not an access port on your data switch, remove the voice vlan from it.
Then retry.

Ah. A different variant of what I was thinking of.
The first server to respond to the DHCP request wins.
Did you have to throw a sniffer on it to find it?

I disconnected that patch lead and restore the back up.. That solved problem.. It was getting ip from the CXi but then it was getting stuck on continuing bootup. I was able to see LLDP on the phones.. But I thought that the cable connected to another dhcp was blocking phones to boot up. Has anyone had this sort of problem? Let me know how you resolved it.. Thanks all...

I suppose you could enable VLAN's as this would also prevent this as the phones would only ever route to the correct DHCP server wherever it is Mitel or Windows/linux

DHCP issues can be very difficult to troubleshoot.
There are quite a few ways that it could be setup successfully and many ways each could fail.
You will need to get pretty specific if you need our help at this point.
Start with what you expect to happen when you plug in a phone.
e.g. (a typical example but not the only one by far)
Plug in phone
Phone starts boot sequence
phone says vlan none priority none
phone does DHCP discovery
phone says releasing
phone says vlan 2 priority 6
phone does another DHCP discovery
phone receives ip address x.x.x.x
phone says ICP at address X.X.X.X
Phone startup
phone Functional

@kwbmitel:
It performs all the boot sequence you mentioned. The only difference is it comes up with VLAN 1 priority 6. Because I have set it to 1. Except that it performs all the steps you mentioned.

Phones are working now.. But system freezes itself some times like it happened on last week monday and friday. I cant log on to the esm. Phones gets stuck on the continuing boot up after getting ip from DHCP. I have to resart system manually. After that sometimes system might come up or might again freezes up itself. It works fine some days and again gets stuck. I dont know whats going on there.
It looks a lot like a broacast storm:
I bet there is a cable looping two switches together, watch for uplinks.
