# Monitoring the placing call state

If the application receives NCCEVN_PLACING_CALL while the call is in the outbound initiated call state, the protocol successfully seized the line and resolved glare. The call advances to the placing call state. The call remains in this state until an event occurs indicating a state change:

This event... | Indicates that...
NCCEVN_CALL_PROCEEDING | The switch accepted the call setup request and is in the process of ringing the receiving end. The call is now in the proceeding call state.
NCCEVN_CALL_CONNECTED | A connection now exists between the calling parties. The call is now in the connected call state.
NCCEVN_CALL_DISCONNECTED | The remote party hung up. The call is now in the disconnected call state.

If the protocol supports the ability to overlap sending of digits, the application sends the remaining digit strings with nccSendDigits while the call is in the placing call state. For more information, see Sending overlapped digits.
