SIP Session Management

The OmniVox3D Application Server includes a powerful SIP Session Manager. This manager is a SIP Back-To-Back User Agent (B2BUA), a type of SIP Proxy Server that provides the front-end interface to OmniVox3D for incoming SIP calls. The SIP Session Manager has the following functionalities that are important for creating SIP-based telephony services:

? Program control ? Answers calls, performs call dialogs, transfers, and ends calls under the program control of the OmniVox3D Application Server, and handles call dialog programs provisioned using the OmniView Service Creation Environment.

? Interface to media servers ? Interfaces to standards-based voice and video media servers powered by Dialogic HMP Software via SIP with MSML or VXML markup languages. These media servers are used for playing voice and video messages, message recording, and the collection of DTMF digits and speech recognition data from/by the caller under program control of the OmniVox3D Application Server.

? Call control ? Bridges SIP call signaling to a destination user agent or gateway, and can be used for prepaid billing and call center applications. Under program control of the Application Server, it is able to control the length of destination calls, interrupt and play warning messages (with media servers using Dialogic HMP Software) and perform "follow-on" calls. Because the SIP Session Manager integrates the SIP signaling, media servers and gateways can be freed efficiently from pure SIP calls once a call is routed.

? Real-time billing controls ? Controls the length of destination calls, interrupts and plays warning messages (with media servers using Dialogic HMP Software), and performs "follow-on" calls under the program control of the Application Server.

? Interface to Session Border Controllers ? Interfaces to third-party Session Border Controllers for routing and application services.
