DHCP New IP Each Renewal

Specs: Windows 7
Is there a way to get the DHCP Server to lease a new IP each time a device connects?

I am currently running Microsoft DHCP Server and I have a couple VOIP phones that sometimes get stuck. The VOIP phones get the "url call is disabled," and I would have to assign a new IP to the phone for it to work again. I have to bring in a machine, configure the same IP as the VOIP Phone, reboot the VOIP Phone for it to get a new IP. I can't just reboot the VOIP Phone because the IP is attached to the Mac address so I would get the same IP even after reboot. Is there a way to setup DHCP to hand out a new IP each time a device connects?

This is all internal private IP, not internet public IP. Nothing to do with my ISP.

Give them all static IPs. Why can't you do that?

Phone will get lock up from time to time and I would need to reassign it a different IP for it to work again. I can't manually assign an IP on the phone itself.

Yes the Polycom IP 321. My provider locked the phone so I can't manually configure the IP. If I unlock it, I will lose my warranty. So back to the DHCP handing out different IP each time a device connects?

There were alot of hits when I searched that error message. Repeat the search or call the company.

Yeah I tried that. Google search didn't come up with anything, it only tells me what the problem is. My provider support is pretty useless, they just tell me reboot the phone and my router. I found the solution of changing the IP, but every time I have to force the IP change with another machine. That's why I'm looking for a way for the DHCP server to hand out a new IP each time a device connects or reconnects.

I don't know how to make that happen. I would look for another provider if the tech support is that bad.

I would agree with guapo 100% on this.

You need to find better equipment from a better vendor who supports what they sell. It's rather obvious these guys don't if their advice to all clients with what I would consider a "known issue" with this equipment is "reboot the phone and reboot your router"

They should be fixing the issue.

Regardless, dump them and move on. I wouldn't really recommend Cisco equipment as they gouge on their support packages. They're more than happy to give you great support, providing you supply them with your firstborn male child and the pound of flesh nearest your heart..........

I would do some research and read reviews and look for something that offers both a decent price at the outset as well as reasonable support contracts.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
