VeriCall Phone Editions

VeriCall Phone Editions Streamline DevelopmentManufacturers must also consider evolving industry standards and the specific needs of network operators based on their unique architecture and implementation of communications equipment and systems. When building a new or next generation product, an array of choices exist for both the hardware and software components. For VoIP in particular, consideration must be given to software such as the codecs, SIP stack (media/call control), applications and graphical user interface (GUI). Often, the single largest challenge in designing VoIP products today is the integration and optimization of these disparate software components. In terms of (processor) hardware, the choice of silicon becomes a balancing act as it impacts both the bill of materials (BOM) and the overall performance (and quality) of the end product.

VeriCall Phone Editions eliminate this complexity by ensuring tight integration of all the required software and hardware components, and by providing software development, validation and performance testing on targeted silicon devices — those best suited for Voice over WiFi and Video Phone applications. VeriCall Phone Editions are comprised of the following software modules:

Voice and Video over IP FrameworkThe underlying voice and video over IP framework is built around a proven and flexible architecture. Primary components of the soft-ware architecture include:

Media Processing LibraryThe Media Processing Library includes all of the audio codecs, tone handling, acoustic echo cancellation and other voice quality en-hancement algorithms required to deliver a (bandwidth/quality) range of VoIP services on ARM based processors. Video Phone Edition provides integrated video compression support for up to 30 frames per second video with support for codecs including H.264, H.263 and MPEG-4.

SIP Media/Call ControlVeriCall Phone Editions offer an integrated Session Initiation Protocol (SIP) stack and Realtime Streaming Protocol (RTSP). Also supports the use of independent call control stacks (proprietary implementations of SIP and H.323).

SIP Stack — The Trinity Convergence SIP stack is opti-mized for voice over IP end-points and delivers proven interoperability.

SIP Security — The SIP stack supports the usage of encryption via Transport Layer Security (TLS). This allows customers to implement the specific encryption needed for their application.

NAT TraversalNetwork Address Translation (NAT) Traversal features allow calls to be placed and received from behind rout-ers that implement NAT. The NAT Traversal clients are pre-integrated and cooperate directly with the media processing components of the platform, eliminating the need for additional configuration by in-house develop-ment teams. VeriCall Phone Editions also implement the STUN (RFC 3489) and TURN (STUN relay draft) protocols.

Packet HandlerThe Packet Handler provides quality of service (QoS) and packet framing functionality using Adaptive Jitter Buffer Management and Real Time Protocol (RTP)/Real Time Control Protocol (RTCP).

Data Manager InterfaceThe Data Manager Interface (DMI) is a hardware abstraction layer providing an API for integrating customer specific audio, video and networking components.
