C# SOFTPHONE WITH DO NOT DISTURB
-
Version
9.2.0
Ozeki VoIP SIP .NET SDK allows to develop Do Not
Disturb (DND) function for SIP softphones. If
DoNotDisturb flag is set to true, the incoming calls
will be rejected by a busy signal. The Ozeki VoIP SIP
SDK makes it possible to extend this program with more
features like call hold, call forwarding, call
transfer, auto answer, SIP/SDP message manipulation,
.mp3 and .wav playing support, etc. The softphone is
customizable with your own company name. The Do Not
Disturb functionality is really simple to handle when
you use Ozeki VoIP SIP SDK. DND indication can be
implemented in more ways. Either the client of the
caller can show the presence information of the
contacts or the DND can be only showed by sending an
auto answer message about the fact that the caller does
not want an incoming call. The DoNotDisturb is a simple
flag related to the phone line. The SDK provides all
the background for the DND function. If you set the
DoNotDisturb flag to true, the incoming calls will be
rejected by a busy signal. The easiest way for
extending your softphone with DND functionality is to
use a simple checkbox, that indicates if you want to
get incoming calls or not. Since the Do Not Disturb
function is indicated by the checked state of the new
checkbox on the GUI, a new event handler method is
required that notifies about the check changes. The
method sets the DoNotDisturb property of the phone line
according to the check state of the checkbox, if there
is a valid phone line. In the case if there are no
phone lines, the method does nothing. Ozeki SIP SDK
offers various products and possibilities: Softphone,
VoIP client applications: Dialers, Call assistant, Call
center clients, Call center servers, PBX systems, IVR
systems, Webphone solutions, Conferencing systems,
Voice recording systems, VoIP tunneling systems,
Security monitoring systems, Mobile communication
systems. Royalty free licensing is also ensured and a
purchased Ozeki SDK license can be used for as long as
you wish
