Using the VoIP (Voice over IP) protocol, the Ozeki VoIP SDK enables you the main functions of a virtual phone through which you can create your own VoIP application.

Ozeki VoIP SIP SDK is a much better equipped device than a common phone in terms of functionality, comfort and qualitative audiovisual qualities.

Ozeki SIP SDK is different from other VoIP SDK products because it offers you an out-of-the-box solution when it comes to softphone development.

1. BASIC FUNCTIONS OF THE SOFTPHONE:

These are the very basic functions that a full-featured softphone should support:

• register with a SIP PBX

• send and receive calls and audio and video messages

• use audio devices: microphone, speaker, headphones

• play a voice call and play a wav and mp3 file

• play voice from the microphone in a SIP voice call

• play the incoming voice on the speaker

• recognize incoming voice

• accept, reject, forward and transfer an incoming call (using blind transfer and attended call transfer) and how to put it on hold

• use DTMF signaling

• Auto answer (AA) and do not disturb (DND)

• make a video call (and play an avi)

• use video devices (camera and video playback)

Make/Receive phone calls

For a soft phone, it is the basic functionality to be able to make and receive phone calls. As a prerequisite for having a successful phone call, you can call your partner only in case the other endpoint has previously accepted you as a contact, furthermore, both parties must be online and available. Thanks to the appropriate softphone applications, the status of the contacts is visible, as well as the availability of the necessary technical devices. You have the potential to make your job easier and more efficient with the Ozeki VoIP SIP SDK, which provides these prerequisites and offers expanded codec and feature support.

Video call

Depending on your goals, video calling can also be a basic feature on your softphone. This feature can be used for multiple purposes during conference calls, office meetings, and conferences, and is especially useful when participants are keeping their distance from each other. To enable a qualitative video call, you must have a webcam and a suitable video card.

Audio and video messages

(By means of a keyboard, you can send voice and video messages, and due to some special buttons you can enable voice recording, start and end it, etc. Due to Ozeki VoIP SIP SDK, all necessary special buttons are provided and your only task here is to connect them to your function buttons). Ozeki VoIP SIP SDK also allows to handle voice and video messages in the most effective way. Makes special buttons available on your softphone GUI that are for start/end voice recording etc.

In terms of technical background, both endpoints must have the same codecs used for voice calls and use the proper audio compression techniques to transfer voice. You need to be careful in choosing the right compression technique. To demonstrate this, the higher the number of packets for compression you have, the more packet loss it can cause. Ozeki VoIP SIP SDK gives you extended codec support with G711 A-low logarithmic algorithm which ensures the lowest possible data loss during a data compression.
