openUC Product Architecture openUC Product Architecture

The openUC SSOA SIP Service Oriented ArchitectureTM was shaped by the way the Session Initiation Protocol (SIP) standard was originally written.  Unlike many other products where SIP capabilities were added later and as an additional feature, openUC was built as a native SIP product. All features are implemented in SIP and based on the relevant standards.  No additional feature servers are required.  The Java based management system is designed as a Service Oriented Architecture (SOA) that naturally facilitates business process and application integration using Web Services.

openUC is made to enable cost-effective managed services delivery including cloud deployments.  It's lean and efficient resource footprint enables both embedded systems applications as well as virtualized cloud deployments.  Surrounded with modern tools, openUC integrates into an existing IT infrastructure and established best practices for management, monitoring and reporting.

openUC scales and offers powerful load-sharing redundancy options because media traffic for voice and video does not traverse the server, but is routed peer-to-peer on the LAN.  Zero impact server outages, crystal clear voice and video quality and the ability to deploy openUC as a distributed system are some of the key advantages.

openUC architecture

At its core openUC is a Session Initiation Protocol (SIP) Session Manager paired with an XMPP Instant Messaging & Presence server and a Media Server.

The SIP Session Manager routes communications sessions across a network similar to an IP router that routes IP packets or an email server that routes email messages. It is self-healing, redundant, and load-sharing. This means that in-progress voice or video calls are not affected by a sudden server outage. It also means that media traffic is routed on the network (LAN or WAN) direct peer-to-peer between end points so that the SIP server never becomes the bottle neck or a single point of failure.

The openUC IM & presence server fully suports the XMPP protocol and comes with all the enterprise features included. It supports group chat and file transfer, can handle a wide variety of clients including clients on smartphones. It is closely federated with the SIP side of openUC to represent federated presence. Call escalations are easy with openUC going from chat to a voice/video call or group group chat to a conference call.
   
The openUC media server provides state-of-the art and high definition media handling for voicemail and conferencing applications. It is a pure software based solution requiering no specialized hardware.

Typical openUC Deployment Typical openUC Deployment

openUC can be deployed at customer premises in a data center, or hosted remote.  Call control is provided as a service over IP out to all the different locations, including across borders and oceans. Emergency calling is maintained at all times using branch gateways.  Least cost routing is offered as a standard feature between all locations.  Adds, moves, and changes are easy and do not require any rewiring.  Centralization of trunks reduces cost and allows mixing of PSTN trunks with SIP trunks.
