I am currently using a 2811 router with CME. I have a 24 port Cisco 3560. As for the DHCP, we are using our Juniper SSG5 firewall to provide the addressing. This is the same setup that we have working at other sites. I have went through the configs and compared them to the working setups and it all looks fine. I am now sure what else to try. This is a new build for me. The others were built by a vendor. Any assistance is appreciated!
