### Connection ID (cvCallActiveConnectionId)

The global call identifier for the gateway call. The global call identifier is used as an unique identifier for an end-to-end call.

### Coder Type Rate (cvCallActiveCoderTypeRate)

The negotiated coder rate. It specifies the transmission rate of voice or fax compression to its associated call leg for the call.

### Noise Level (cvCallActiveNoiseLevel)

The active noise level for the call.

### ACOM Level (cvCallActiveACOMLevel)

The sum of echo return loss (ERL), cancellation loss (echo return loss enhancement), and nonlinear processing loss for the call.

### Output Signal Level (cvCallActiveOutSignalLevel)

The active output signal level that the call sends to the telephone interface.

### Input Signal Level (cvCallActiveInSignalLevel)

The active input signal level that the call receives from the telephone interface.

### ERL Level (cvCallActiveERLLevel)

The current echo return loss (ERL) level for the call. The value -1 means the level can not be determined or level detection is disabled.

### Session Target (cvCallActiveSessionTarget)

The session target of the peer that is used for the call. It is set with the information in the call associated in cvVoicePeerCfgSessionTarget when the call is connected.
