Re: Dhcp request from the phones

This will be processed for the phone first come online and try to DHCP IP address and register with CUCM (if you set up correctly)

 

are this messages you see after you getting the DHCP IP and also register with CUCM ? or Phone never registering?

 

here is the reference guide for DHCP 53 and other options in case required to refer :
