I have a customer who's phone are IP phones. You pass through them to get to the network. The other day the phones were having problems and the phone company blamed it on a computer. They said that one of the computers was doing an arp call with the destination IP of 0.0.0.0 and it was causing the phone to drop calls and/or reboot.
I think they are full of it but want to know. Is there a program available that will monitor arp calls that I can continuously run on either a 2012 Server or a Windows 10 client that will show any arp calls going on?
