The watchers are the DLLs and they monitor telephony related information such as signal strength, battery level and call states. The telephony watchers use <xref href="GUID-FE910347-7CC1-5241-B443-88AD3F5A96EF.dita">publish and subscribe</xref> to publish the information. The client applications must register with the watcher to receive the updates from the telephony system. </p> <p>The telephony watcher framework contains two watcher plug-ins: </p> <p><b>Signal strength watcher </b> </p> <p>The signal watcher notifies all registered client applications of the changes to the radio signal strength. </p> <p><b>Call indicator watcher </b> </p> <p>The call indicator watcher notifies all registered client applications of the call progress information of active voice, data and fax calls. </p> <p>The watcher classes get the state information from the multimode telephony API and publish the notification to the registered client applications. </p> </conbody></concept>
