I have a 7200 with 4.75. Three of the 5220 phones have 64 button AOM's. The consoles stop working about twice a week. They have to unplug the LAN cable to reset.

The 5220 is powered by a POE switch in the IT room. I though of putting the phones on their own power-supply's and getting them off the 48 port POE switch to see if something network related was causing the modules to stop working.

Has anyone seen this?
Thanks

Have you checked to make sure that the console is not having an ip conflict with another device on the network? Possibly someone that brings in a laptop or cell phone twice a week into the office. Causing it to mess up.

Thanks. I did think of that and have the IT people looking into it.

They did give us a new IP range that will be exclusively used for the consoles.

Is it just the AOM's that stop working or both?

What happens when the AOM's stop working?

Do you have the phones plugged in via the AOM's? (they will pass the PoE through to the pc port from the AOM lan port)

What does the system show the status of the AOM's as when they stop working?

What they are now saying is, is that the consoles work, but the lights at times don't. And they are saying that sometimes the lights are red, when no one is on the phone.

The main phone always work

Are you saying from the POE port (wall jack)to the console, and then out to the phone?

We have it from the wall to the 5220, and then a short cable to the console.

Thanks,

Yes,

Otherwise you need 2 poe ports (or a psu for the AOM)

We did have them patched correctly. We reset the 7200 and no change. Lights did not work on the consoles if someone was on the phone, or if pressing the button to call a user. They started working after a power down and back up of the phones.

I am thinking we might have a issue with 4.75

Thanks,

I had the exact same problem. My issue was that the AOM worked just the BLF's would stop. We suspected that it was something on their network causing this, but could never prove it. Even after countless wiresharks between the PBX and the data network.

If you have remote access, try bringing up the aom from your shop and see if the lights stop, my guess is the AOM will work just fine.
I got lucky as this customer had a second internet connection in their conf room, so I ran a cable to that separate network and brought up the IP phone and the AOM as a remote phone. Never had any problems since.

That's sounds like a good plan. I may upgrade the software too.
Just to see if that helps. Do you recall what software you were on?
Thanks,

Use three different IP for each, once you change the IP address then you will get this problem again. The following error is occurring just because of the IP Conflict.

We finally got a 5220 and the AOM up remotely at our shop. The AOM works great. No issues. The main site continues to have problems with the other 2 AOM's.

Each AOM has its own IP assigned.
Thanks
