BlackBerry DTMF tones
BlackBerry® devices play DTMF tones as soon as no other tones are pending, overriding conversations.
DTMF tones consist of a low and a high frequency, which are played at the same time.
Retrieve phone call information. > Use the methods of the
PhoneCall

int threshold = 120; // Alert user if outgoing calls last longer than
threshold.
int elapsedTime = call.getElapsedTime();
// Use getStatusString() to retrieve status as an string.
int status = call.getStatus();
if ((status == PhoneCall.STATUS_CONNECTED || status ==
PhoneCall.STATUS_CONNECTING) && call.isOutGoing() && elapsedTime >
threshold) {
// Use getCallId() to retrieve the caller ID as as an integer.
String phoneNumber = call.getDisplayPhoneNumber();
Status.show("Your call to " + phone " has lasted more than " +
(String)thr ".");
}
