VoIP tests can only happen after the DSAM has successfully ranged and registered with the CMTS in the headend.

NOTE:

- VoIP test can only be initiated after the DSAM has successfully registered with the CMTS, and the MTA has successfully initialized.
- VoIP mode shall not be initiated if Ranging Only is configured.
- A call cannot be placed or received if registration with the CMTS has failed.
