No, a SIP device will not register with CUCM unless it has a DN, you'll have to give them mock DNs for this purpose.

SIP phone users REGISTER message for registration purpose and SIP-Id (/DN) is mandatory in REGISTER message, hence you have to have DN assigned to phone for successful registration.
