i2002 Phones rebooting

I've got an office that's really giving me a headache. I sent some i2002's that are configured to connect to a BCM 400. There's a VPN link from that office to the main office.

The phones were configured in another remote office and tested every way. I sent the phones to the new office and they said everything worked, they just couldn't get an outside line. Yes.. they said they dialed 9. I checked the programming and everything was in order. I had them send the phones back to me. I plugged them in and there were no problems dialing out.

I remotely set up a 2005 soft phone at their office and it worked fine. Everything on the i2002's worked. I could call them from outside, I could call them from inside, they could call each other. They just said they couldn't dial out.

So I sent the phones back figuring that it's just user error.

They've plugged the phones back in and they said that they don't work at all now. This is what they describe:

It turns on.
Nortel Screen.
DHCP Screen... then the screen goes blank and it repetes the Nortel and DHCP screen.

It does this over and over again. I asked that they try a different phone: same.

I asked that they try a different power supply: same.

I asked that they start the phone without the network cable plugged in. Now it just stays at the DHCP screen without rebooting.


I don't know what crazy stuff is going on down at that office and right now I have no qualified people there. The office is supposed to go live on Monday.

Does anyone have any explanation for why the phone is restarting like that? Is that a behavior that commonly happens when {X} is wrong? Any help would be appreciated.

Then... any ideas on why everything would work except getting an outside line in one office while the smae phone plugged in to another remote office would work just fine???

Thanks!

Mike,
Have the phones already been registered to the BCM?
Is the BCM supplying the DHCP or a network DHCP server?

I typically see this symptom when the DHCP is unreachable or the VLAN is configured incorrectly.

Do you have the latest patch on the BCM so that it is using the most recent firmware?
 
Yes, it's all patched up.

It's not all phones in all offices. Just this one particular office.

The phones were fully configured off-site, then shipped to the office.

The network is supplying DHCP and it appears that they are getting addresses.
 
OK, well I figured out a solution, sort of.

I was told that they changed their DHCP server from a Windows 2003 server to DHCP being served up by a SonicWall Firewall.

You can see it register itself on the sonicwall, but then it ends up restarting and clearing out. There's something that Windows DHCP is providing that the Sonicwall is not.

I'm not sure if it's a manual VLAN setting I need or if I need to modify the DHCP settings.

There is no VLAN, so I'm not certain how to configure that.
 
VLAN was set to manual so that didn't seem to be the issue.

For now, I've given the phones static IP addresses and that has solved the problem. I wonder what it is about SonicWall DHCP that is causing the phones to reboot.
 
You may want to check out the DHCP Offer Message.
I know it has to be in a specific format.
Maybe you can look at the setup in your other DHCP server.
Depending on your software version you may be able to configure the BCM to DHCP only to the IP sets.
