[MobilePRwire] – Jump Start your Mobile Handset Application, Harness the Power of VoIP Engine: Voice Engine/SIP Software Development Kits for VoIP Application ARM®, iOS, and Android™ Developers. Adaptive Digital’s VoIP Engine™/SIP Reference Kits, include both a voice over internet protocol (VoIP) engine SDK, and a Session Initiation Protocol (SIP) SDK which can be used together to accelerate the development of cutting edge VoIP applications, while delivering the best user experience for mobile clients.

Do you have VoIP features and custom functionality in mind for your application, but don’t know quite where to start? Do you want to shorten your implementation timeline, and accelerate your overall product development? Well if so, then VoIP Engine/SIP Reference Kit is for you!

Plymouth Meeting, PA, April 10, 2013 – In competitive world of mobile application development, there is enormous pressure to get the next major product to market quickly. Adaptive Digital Technologies’ VoIP Engine Development Kit ensures that there is no trade-off between speed-to-market and product quality. Adaptive Digital’s VoIP Engine™/SIP Reference Kits, include both a voice over internet protocol (VoIP) engine software development kit (SDK), and a Session Initiation Protocol (SIP) SDK which can be used together to accelerate the development of cutting edge VoIP applications, while delivering the best user experience for mobile clients.

Implementing full-duplex voice and acoustic echo cancellation on the mobile handsets is far more challenging than implementation on a desktop phone. Besides the acoustics being a challenge, the audio drivers have issues as well. Adaptive Digital’s customizable integrated solution, VoIP Engine, is a software framework that takes an audio stream and performs all the processing necessary to hand off an RTP packet to the network stack, and the same in the opposite direction. It is a data processing engine.

VoIP Engine SDK features acoustic echo cancellation, noise reduction, and automatic gain control (AGC) for voice quality enhancement (VQE), as well as speech compression (G.711, G.729AB, and G.722 and other optional codecs), RTP and Jitter Buffering.

Our SIP SDK provides a customizable solution to quickly add SIP based dial and receive phone calls features in your software applications. It supports: registration, call initiation, call-acceptance, and call-teardown for VoIP telephones.

Exacerbating the problems of the competitive mobile market, there are inherent hurtles to overcome when developing and deploying applications to different mobile platforms. To alleviate the difficulty, we have several platform reference kits you can import into your development environment to get up and running quickly. VoIP Engine/SIP Reference Kits are available on the following platforms: iPVoice™ for iOS based devices, and AnVoice™ for ARM/Android based devices.

Reference Design Kits include:

iPVoice™ – VoIP/SIP Reference Kit for iPhone®, iPad®, and iPod touch®
• SIP Phone Sample Project with source code (iOS)
• iPVoice SDK (includes time bombed iOS class library, header file and docs)
• SIP SDK (includes time bombed class library, header file and docs)

Q2 2013! AnVoice™: Android VoIP/SIP Reference Kit

By using Adaptive Digital’s VoIP Engine/SIP Reference Kits you can accelerate the development of SIP compliant voice applications. You can add VoIP features to an existing application project or create a fully customized SIP application. The sample SIP Phone app (included) is a fully functioning SIP phone. The app can be configured to connect to a standard SIP server. It is configured to place outgoing phone calls as well as receive inbound phone calls. Furthermore, it supports peer to peer VoIP for applications that do not require SIP, opening the door to many new applications.

The API is clean and simple to use. In fact, developing your own VoIP enabled app is as easy as customizing one of our sample SIP Phone apps, which are provided in source code format as part of the SDK.

Included in the Reference Kit is G.722, a wideband compression algorithm, passing 7 kHz of audio bandwidth rather than the 4 kHz that is carried by wired phones and cell phones. The result is crystal clear voice, the likes of which is impossible in the public switched telephone network.

Download our sample app onto two or more phones and try it out for yourself.

About VoIP Engine
VoIP Engine is a framework that bundles together many algorithms such as conferencing, vocoders, noise reduction, echo cancellation, etc. required in a VoIP application. Although VoIP Engine is more integrated than an algorithm, it is still not an application. It is a data processing engine. VoIP Engine has no interface to drivers or peripherals and performs processing solely at the request of the host application. This makes VoIP engine portable for use in conjunction with any application or operating system.

VoIP Engine is more than just a collection of algorithms packaged in a library. It connects them together. For example, in a PCM to Packet configuration, VoIP Engine is fed a PCM stream by an application. It processes the PCM through echo cancellation, noise reduction, AGC, speech compression, RTP, etc. and it returns a complete RTP packet to the application. Similarly, in the opposite direction, the application feeds VoIP Engine with an RTP packet and VoIP Engine returns PCM samples.

VoIP Engine is intended use is in VoIP enabled handsets or desktop phones. Although VoIP Engine is not tied to any particular software environment, it was designed with Android™, iPhone™ Windows, and Linux in mind.
