Virtual SNR DN only supports Cisco Unified SCCP lP 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.
