| If dwParam1 is PHONESTATE_RING, then dwParam2 contains the new ring mode. | |

| Comments | The sending of this message is controlled by TSPI_phoneSetStatusMessages. By default, this message is disabled for all state changes. |
| Comparison | The Service Provider never reports changed values for PHONESTATE_OWNER or PHONESTATE_MONITOR, since the notion of privilege does not appear at the TSPI level. |
