# Call-Related Events

The latest VoiceXML 2.0 and 2.1 specifications define a set of events named `connection.*` and `error.connection.*` to report call-related status/failures, rather than `telephone.*` and `error.telephone.*` (which were defined in earlier versions of the VoiceXML 2.0 specification).

The IP Media Server platform supports the `*connection*` events, for compliance with the naming convention used in the latest specifications. For backward compatibility, the platform continues to support the `*telephone*` events as well. Since there is no way for the platform to throw both "connection" and "telephone" events at the same time (multiple events cannot be thrown simultaneously), a new property - `com.voicegenie.useconnectionevent` - is added to specify which naming convention the platform should use when throwing call-related events.
