To configure a virtual SNR DN on Cisco Unified SCCP IP phones, perform the following steps: Prerequisites - Cisco Unified CME 9.0 or a later version. Restrictions - ✑ Virtual SNR DN only supports Cisco Unified SCCP IP phone DNs. ✑ Virtual SNR DN provides no mid-call support. Mid-calls are either of the following: Calls that arrive before the DN is associated with a registered phone and is still present after the DN is associated with the phone. 

Calls that arrive for a registered DN that changes state from registered to virtual and back to registered. 

✑ Mid-calls cannot be pulled back, answered, or terminated from the phone associated with the DN. ✑ State of the virtual DN transitions from ringing to hold or remains on hold as a registered DN.
