You need to wireshark it. Bet you anything you are getting DOS attacks or a conflicting IP address. Something changed. If Cisco make sure CDP (Cisco Discovery Protocol) is off.

Still trying to figure out why this is happening

IT company doesn’t see any IP conflicts

All residents DID calls come into System A then go to System B

At some point the calls get hosed up and will get answered by AA which should never happen


The only way to correct it is to reset System B (Residents)

I forgot to mention the fact that the call get picked up by AA when not working correctly

The residents do not use the voicemail system

I will have to go back out and look at the port activity on IntraMail

I have no idea what you are trying to trouble shoot. The AA is picking up because of system programming somewhere that dumps it there. Depending on the IT company is not the best way to go at this. You need to be wiresharking this when this fails. Resetting the system fixes it but what is causing it. You need to be looking at the traffic on System B. I've seen this a thousand times where a rogue device is causing a DOS attack on that ethernet port cause the buffer to fill up and cause it to stop working. The IT company cannot see this. This is clearly a networking issue of some type.
