The SIP Server Platform is a Software Development Kit (SDK) that provides all the necessary building blocks required to develop SIP Server applications. Using the SIP Server Platform, developers can easily implement a wide variety of SIP server applications, such as IMS servers or Unified Communications applications. The SIP Server Platform is part of a family of IMS and SIP products and services, such as the IMS Developer’s Suite and IMS SIP Server solutions.
Formerly Radvision SIP Server Platform or SIP Server Framework
Key highlights
Shortened development cycles
You focus on the application while the platform focuses on the infrastructure
Interoperability
The product provides assured interoperability with market-leading products with periodic interoperability testing
High performance
Horizontal scaling achieved by higher transaction per second performance
Control
Ability to control everything, down to the bits and bytes
For developers of
- IMS Application servers: Presence, event notifications, call control, billing
- Interworking function
- P/I/S-CSCF
- BGCF
- SCIM (Service capability Interaction Manager)
- Security gateway
- SBC (Session Border Controller)

Architecture
Key highlights
OS Abstraction Layer
This layer implements the decoupling from the OS, providing easy porting between operating systems, and hiding a portion of OS API complexity.
IMS SIP Stack
The IMS SIP stack implements the SIP messaging layer of the SIP server. The SIP stack is the first commercial IMS SIP-compliant stack.
SIP Server Core
This layer implements the message dispatching and some additional core functionalities, such as configuration management.
Presence & Event Server
Implements Presence server with complete presence event package and WINFO. This module is also the framework for every application based on diverse event packages.
B2B
The Back-to-Back module provides the engine and implementation for sophisticated call-control features and general SIP B2BUA functionality. The B2B has a unique modular architecture that can be used for developing sophisticated SIP applications. For additional information, please visit the Back to Back Application framework information page.
Proxy & Redirect
Implements complete SIP Proxy and redirect server supporting message routing and forking.
Registrar
Implements complete SIP Registrar to handle SIP registrations
Security Component
In-memory database used to store authentication-related information.
Location Component
In-memory database storing the location (IP address) of local SIP terminals.
Reference Implementation
Provides the examples of SIP Server Platform API usage, illustrating how to program several applications, such as a presence server.

Conformance
Standards
The SIP Server platform is continuously upgraded to support the latest IETF SIP and IMS SIP standards. For more information please refer to the product specifications.
Interoperability
The SIP Server Platform is continuously tested at all major inter-op events.
Common Core
OS Abstraction Layer (a.k.a. common core) makes the SIP Server Platform future-proof. When you decide to change or upgrade the underlying operating system, your previous investment is protect.
