DEVELOP SIP BASED INSTANT MESSENGER
One can easily add SIP based Instant Messiging and Presence feature in its VaxVoIP integrated softphone. VaxVoIP SDK supports SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) protocol.
SIMPLE is the SIP protocol extention to send and receive SIP based chat messages and status (online, offline, away, on the phone etc). So, it really easy to add and develop SIP based chat feature, please see the sample code and demo for more details.
You can dial and receive phone calls through any SIP based server, gateway or ITSP (Internet Telephony Service Provider).
VaxVoIP SIP SDK enables to initialize the component with a user-define specific number of lines. You will be free to start the component with 4, 8, 10, 20, 40, 80 or more number of lines.
Such feature is use to start conference call, consult call transfer, dial/receive multiple phone calls and for many other purposes.
MULTI-PARTY VOICE CONFERENCE
User can dial and receive multiple calls to start conference call.
During the call session, user can put any line on hold.
Forward an incoming call to other phone number, user name or sip account.
Transfer a call to other phone number, user name, sip account or sip uri.
ACOUSTIC ECHO CANCELLATION OR SUPPRESSION
In order to eliminate the acoustic feedback an echo canceller is introduced in the VaxVoIP SIP SDK.
Hands-free or Internet telephony imposes several problems. The principal one is due to the coupling between loudspeaker and microphone. The loudspeaker signal is echoed back to the microphone and transmitted back to its origin. As a result the far-end participant perceives this as an echo.
NOISE CANCELLATION OR SUPPRESSION
VaxVoIP SIP SDK offers advanced Noise Cancellation technology that allows significant suppression of any background noise and produce high quality of output speech.
AGC (AUTO GAIN CONTROLLER)
We support AGC (auto gain controller). AGC is a mechanism by which input voice gain/volume is adjusted automatically based on input signal level.
RECORD CONVERSATION INTO WAVE (.WAV) FILE
During the phone call, you will be able to record the conversation into wave (.wav) file for later play back.
PLAY WAVE (.WAV) FILE TO THE REMOTE END
VaxVoIP SIP SDK export methods to play wave (.wav) file to the remote end.
FRIENDLY TO NAT AND OTHER FIREWALLS
User can set SIP outbound proxy inorder to make and receive phone calls behind the NAT/firewall.
In some cases, ITSP (Internet Telephony service provider) support outbound proxy. Outbound proxy is a way to let the NAT/firewall user make and receive phone calls.
If the NAT/firewall router does not support SIP pass-through, you need to consult your ITSP if they support SIP outbound proxy. Since different NAT router vendor implement NAT differently. Typically ITSP may provide SIP outbound proxy to resolve NAT pass-through issues.
STUN is not a good idea to support NAT pass-through, because STUN does NOT support symmetric NAT type, symmetric NAT is more secure and widely use for commercial purposes. Almost all branded routers support symmetric NAT type, even Microsoft windows SERVER 2000 & 2003 built-in NAT is also base upon symmetric NAT type. Please see STUN RFC for more details.
KEEP-ALIVE PACKETS TO NAT/FIREWALL
VaxVoIP SIP SDK support keep alive feature. When you enable it, VaxSIP component starts sending keep-alive packets and keeps the port open at firewall ends.
NARROWBAND & WIDEBAND VOICE CODECS
VaxVoIP SIP SDK supports for both narrowband and wideband codecs that's why it works with all type of Internet connections.

Jitter buffers are used to smooth delay variations in received audio by buffering the packets and adjusting their rendering. The result is a smoother delivery of audio to the user.
Packet Loss Concealment (PLC) is a technique used to mask the effects of lost or discarded packets. PLC is generally effective only for small numbers of consecutive lost packets, for example a total of 20-30 milliseconds of speech, and for low packet loss rates.
VaxVoIP SIP allows applications to generate DTMF tones.
VaxVoIP SIP SDK also support DTMF tones detection feature.
