C# SOFTPHONE WITH AUTO ANSWER
-
Version
9.2.0
Ozeki SIP .Net SDK to develop auto answering C# VoIP
softphone to auto answer incoming calls. The program
registers to a SIP PBX and waits for incoming calls to
accept. Auto answer can be a previously captured audio
file or a text message that is read up by the VoIP
client. It is based on Ozeki VoIP SIP SDK that ensures
excellent VOIP PBX compatibility (like 3CX, Asterisk,
Cisco UCM, etc.) and online VoIP service provider
(Skype Connect, Gafachi, etc.) support, multiple calls
and lines. The softphone can be customized with further
features to functioning as a full softphone and with
company logo. The basic idea behind this program is
that when there is an incoming call, it is
automatically accepted but instead of speaking to the
caller, the caller listens to a message played into the
call. The program can only register to a PBX with the
specified SIP account and it waits for an incoming call
to accept. When there is an incoming call the softphone
accepts it and the communication can be started. The
GUI of the example program is really simple, it only
contains the PBX registration form, some notification
labels and a button that can be used for ending the
call. As this is an auto-answering softphone you cannot
cancel the call or in this case you cannot even start a
call with it. The actual difference between a normal
softphone and this application is that when an incoming
call comes the call is accepted without waiting for a
user interaction. Ozeki SIP SDK ensures the follows:
CODECS: G.711 aLaw/uLaw, G.729, iLBC, GSM, G.722,
SPEEX, SPEEX-WB, L16, G723, G726-16, G726-24, G726-32,
G726-40, G728. Tools: SIP protocol implementation, RTP
implementation, RTCP implementation, Audio device
support (mic, speaker), Audio encoding / decoding
(audio codecs), Voice quality improvement tools (AEC,
AVG, NR, Jitter buffer), Video device support (camera
and playback), Video encoding / decoding (video
codecs), Implemented network communication protocols:
UDP, TCP; STUN, TURN support
