#include <etel.h> // for dial operatons //LIBRARY etel.lib // for dial operationsTBool CMcAppUi::dialTel(TDesC & telNum) { _LIT(KPHONE_DRV, "phonetsy.tsy") ; //Create a connection to the tel server RTelServer server; CleanupClosePushL(server); User::LeaveIfError(server.Connect()); //Load in the phone device driver User::LeaveIfError(server.LoadPhoneModule(KPHONE_DRV)); //Find the number of phones available from the tel server TInt numberPhones; User::LeaveIfError(server.EnumeratePhones(numberPhones)); //Check there are available phones if (numberPhones < 1) { User::Leave(KErrNotFound); } //Get info about the first available phone RTelServer::TPhoneInfo info; User::LeaveIfError(server.GetPhoneInfo(0, info)); //Use this info to open a connection to the phone, the phone is identified by its name RPhone phone; CleanupClosePushL(phone); User::LeaveIfError(phone.Open(server, info.iName)); //Get info about the first line from the phone RPhone::TLineInfo lineInfo; User::LeaveIfError(phone.GetLineInfo(0, lineInfo)); //Use this to open a line RLine line; CleanupClosePushL(line); User::LeaveIfError(line.Open(phone, lineInfo.iName)); //Open a new call on this line TBuf <100> newCallName; RCall call; CleanupClosePushL(call); User::LeaveIfError(call.OpenNewCall(line, newCallName)); //newCallName will now contain the name of the call User::LeaveIfError(call.Dial(telNum)); //Close the phone, line and call connections and remove them from the cleanup stack //NOTE: This does not hang up the call CleanupStack::PopAndDestroy(3);//phone, line, call //Unload the phone device driver User::LeaveIfError(server.UnloadPhoneModule(KPHONE_DRV)); //Close the connection to the tel server and remove it from the cleanup stack CleanupStack::PopAndDestroy(&server); return ETrue ; }
