I have tried to use CTelephony::Hold().But failed to hold the call. TCallId has three different values, and I have tried them all.
enum TCallId
{
/**
Call owned by this ISV application.
*/
EISVCall1,
/**
Call owned by this ISV application.
*/
EISVCall2,
/**
Max number of calls supported by Etel 3rd Party.
*/
EISVMaxNumOfCalls
};
