I have not seen any docs on this but I would recommend keeping DHCP services off your CallManagers if at all possible. You can decrease the network load on the server, and avoid loss of network service for clients if a CCM goes down. For example, I saw a situation where DHCP was running on one CCM but when it failed over the clients had no place to go for DHCP.
The problem is that we provide a managed service and as such prefer not to use any DHCP service that belongs to the customer. For small to medium size networks I would like to use the existing server and avoid additional hardware expense. The default DHCP lease lasts 8 days, I would expect that if the Call Manager failed we would have it fixed long before any lease expired
