local pc's and voip phones not showing new ips in same label

RouterOS The Dude
1

I have a linksys 310n router, with DHCP to all of our voip phones and computers in the office. I have the dude set up on a pc on the same network with a static ip. I can discover my whole network just fine, but as soon as the DHCP leases end, or a laptop is unplugged and plugged back in later on, the ip changes for that device, and the dude discovers that device under a new ip.

I read the forums about this issue and was told to change dns lookup to name to address and ip to mac, but that didn’t do anything because these devices don’t even have anything in the dns box, so how could that work? What IP do I put in the dns names box for local ip’s? The ip of my router which is 192.168.1.1? What ip on a local network checks to see if an ip has changed? I’m confused! We don’t have a dns server at the office. Any ideas? It’s probably something simple and i’ll kick myself after someone tells me.

I guess i’d like this to work for the agents I have set up for other locations and their local pc’s and phones.

Perhaps it is much easier to put DHCP static lease for users, who are more or less permanent in your network.

The only problem with that is sometimes they take their ip phone home with them, and the subnet is different.

Isn’t there a way for the dude to look at the current mac address of the device, then when it does it’s discovery again, it sees that the newly discovered device matches the mac of a device previously discovered device, and just replaces it? It sounds like something that could be easily implemented. Am I wrong?
