CompactSIP

The TeleSoft CompactSIP User Agent SIP stack offers a highly optimized SIP stack solution that combines a very small memory footprint with high performance and no compromises on functionality and scalability. CompactSIP is a modular SIP UA SDK, written in ANSI ÔCÕ for ease of portation, that is tailored to suit the application thus optimizing both memory footprint and cost.

The CompactSIP User Agent SIP stack is supplied pre-ported to a choice of operating systems for mobile, embedded and PC-based applications. These include Symbian, Windows Mobile & Nucleus for mobile devices; Micrium, MQX, ThreadX, uCLinux & VxWorks for embedded platforms; and Linux & Windows for PCs.

Also available is the TeleSoftPhone SIP client that includes a simple GUI for mobile and PC-based applications.

Available reference designs, with CompactSIP SIP UA SDK ported to and running on, include the Freescale Coldfire MCF5234/5 Low Cost VoIP telephone platform and the PowerQUICC II MPC8323E Multi-Service Gateway platform.

CompactSIP is a tight and fast SIP stack:

Support for methods, headers, and message processing is configurable to save memory.
Typical configuration fits in 128KB.
Just-in-time parser avoids parsing headers not used by SIP stack or application.
Optimized handling of timers avoids high start/stop overhead.
Crafted parser eliminates typical parser-generator bloat.

Top

CompactSIP Source Code Stack is easy to use:

Low-level API provides complete control over all SIP functions and message content.
API supports multiple independent services including multi-homing.
User can easily add special method and header processing.
SDP parser is separate from SIP parser for use in other SDP applications.

Top

CompactSIP is easily ported to any environment:

Portable to any memory model, including flat, heap, pool-based, and mbuf or zbuf.
Object-oriented API supports direct function-call interface, inter-task and inter-cpu messaging.
Highly scalable – no built-in limits other than those required by the system itself.

CompactSIP provides a broad development and debugging environment :

Ports include Linux, Micrium, MQX, Nucleus, Symbian, ThreadX, uClinux, VxWorks, WinXP, Win Vista & Win Mobile.
Available pre-integrated to GlobalIP Solutions (GIPS) VoiceEngine for high quality voice and video solutions.
Comprehensive example applications to demonstrate use of the APIs.
Sample make files and imake scripts.
Debugging & auditing features allow compile-time & run-time details for logging of messages & events.
