3GPP WiMAX IMS_SIP Protocol Stack

IMS / 3GPP / WiMAX Compact SIP Software

TeleSoft International provides 3GPP WiMAX IMS SIP source code software to accelerate development and interoperability testing of your SIP product. TeleSoft's SIP protocol stack provides the fastest path to market-ready VoIP products for manufacturers worldwide.

TeleSoft International is a premier supplier of circuit switched telephony and VoIP Protocol signaling stacks & solutions to leading OEMs worldwide. TeleSoft has been selected by more than 250 OEM customers and we continue to provide robust, mature, conformance and interoperability tested solutions to customers who require the best performing software stack solutions.

IMS CompactSIP addresses the needs of manufacturers developing 3GPP and WiMAX handsets and other mobile IPphones (Internet phones), datacards, mobile platforms and chipsets by providing a 3GPP/IMS compliant software stack that supports the key 3GPP authentication and security standards plus the required IETF SIP RFCs. The 3GPP/IMS CompactSIP stack was jointly developed between TeleSoft International and the world’s #1 mobile service provider in order to bring you the smallest, most efficient SIP protocol software solution for the 3GPP, WiMAX and IMS markets. IMS CompactSIP is tested to be standards compliant and network interoperable using in-house IMS handset emulators and network simulators plus private access to live 3GPP networks.

WiMAX standards call for similar, if not identical SIP features. We expect that WiFi will also use many of the same voice enabling features that 3GPP and WiMAX have called out.

IMS CompactSIP is ideal for all applications where compact memory space and fast code execution are important. IMS CompactSIP is also available integrated and tested with the Interpeak IPNET TCP/IP networking stack as the IMS SIPNET product.

IMS CompactSIP is tight and fast:

	Support for methods, headers, and message processing is configurable to save memory.
	Smallest configuration fits in less than 100KB.
	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.

IMS CompactSIP 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.

IMS CompactSIP is easily ported to any environment:

	Portable to any memory model, including flat, heap, pool-based, and mbuf or zbuf.
	Follows coding conventions used by other TeleSoft software stacks.
	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.

IMS CompactSIP provides a broad development and debugging environment:

	Sample applications to demonstrate use of the APIs.
	Initial ports include Linux, uCLinux, VxWorks, Nucleus, Windows and TsRITE OSes.
	Sample make files and imake scripts.
	Debugging & auditing features allow compile-time & run-time details for logging of messages & events.

Compliance Testing:

	Exclusive in-house 3GPP Handset emulator and Network Simulator test platforms.
	Private access to 3GPP networks allow extensive live testing.
	Rigorously tested against IETF & PROTOS torture test suites and 3rd party equipment.
	Successful SIPit Interoperable testing against multiple vendors equipment.

TeleSoft International is the original developer of the TsLink3 range of high performance WAN protocols including SIP, ISDN BRI and PRI, QSIG, CAS E1 R2, T1 RBS, AO/DI, ML-PPP, Frame Relay, X.25, and also a range of hardware reference designs. TsLink3 protocol source code is exceedingly well engineered - tightly coded for performance and compact footprint, with a quality that delivers rock-solid stability.

TeleSoft's foundations go back to 1986 when the first ISDN stack was released. Since then TeleSoft's protocols have been proven in use by more than 200 customers worldwide. World leaders, including AT&T, Cisco, D-Link, Digital Equipment, Fujitsu, IBM, Lucent, Matsushita, Multi-Tech, NTT, Polycom, and Vertical Networks have all used the source code for TeleSoft's proven protocol software.

Manufacturers license the source code for TeleSoft's proven Protocol Stacks and Reference Designs to get their products to market faster with minimized technical risk and development costs. TeleSoft focuses on developing the software and hardware so that you can focus on manufacturing and shipping your product.
