Using the Telephony Independent Software Vendor (ISV) API</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>This set of seven example applications demonstrate the use of the Telephony

ISV API provided by the <xref href="GUID-97D402C8-B4B7-385A-92B3-D3FCC0CA575A.dita"><apiname>CTelephony</apiname></xref> public interface to

the phone’s telephony system. This interface enables developers to access

common mobile telephony services, such as finding phone information, dialling

and answering voice calls. </p>

<p>Each example demonstrates a different set of mobile telephony services,

and is stored in a subdirectory of <filepath>ETel3rdPartyExample</filepath>.

These subdirectories are explained in the description section. </p>
