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.
