<H1><A NAME="_tapi2_phonesetring"></A>phoneSetRing</H1>
<P>The <B>phoneSetRing</B> function rings the specified open phone device using the specified ring mode and volume. </P>
<PRE class=syntax><B>LONG WINAPI phoneSetRing(
HPHONE</B><I> hPhone</I><B>, </B>
<B> DWORD</B><I> dwRingMode</I><B>, </B>
<B> DWORD</B><I> dwVolume </I>
<B>);</B></PRE>
<H4>Parameters</H4>
<DL>
<DT><I>hPhone</I> </DT>
<DD>A handle to the open phone device. The application must be the owner of the phone device. </DD>
<DT><I>dwRingMode</I> </DT>
<DD>The ringing pattern with which to ring the phone. This parameter must be within the range of zero to the value of the <B>dwNumRingModes</B> member in the <A HREF="struc2_8rua.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/struc2_8rua.htm"><B>PHONECAPS</B></A> structure. If <B>dwNumRingModes</B> is zero, the ring mode of the phone cannot be controlled; if <B>dwNumRingModes</B> is 1, a value of 0 for <I>dwRingMode</I> indicates that the phone should not be rung (silence), and other values from 1 to <B>dwNumRingModes</B> are valid ring modes for the phone device. </DD>
<DT><I>dwVolume</I> </DT>
<DD>The volume level with which the phone is ringing. This is a number in the range 0x00000000 (silence) to 0x0000FFFF (maximum volume). The actual granularity and quantization of volume settings in this range are service provider-specific. A value for <I>dwVolume</I> that is out of range is set to the nearest value in the range.
</DD>
</DL>
<H4>Return Values</H4>
<P>Returns a positive request identifier if the function is completed asynchronously or a negative error number if an error occurs. The <I>dwParam2</I> parameter of the corresponding <A HREF="msgs_0ut5.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/msgs_0ut5.htm">PHONE_REPLY</A> message is zero if the function succeeds or it is a negative error number if an error occurs. Possible return values are: </P>
<P>PHONEERR_INVALPHONEHANDLE, PHONEERR_NOMEM, PHONEERR_NOTOWNER, PHONEERR_RESOURCEUNAVAIL, PHONEERR_INVALPHONESTATE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALRINGMODE, PHONEERR_UNINITIALIZED, PHONEERR_OPERATIONUNAVAIL.</P>
<H4>Remarks</H4>
<P>The service provider defines the actual audible ringing patterns corresponding to each of the phone's ring modes. </P>
