SIP Overview
Session Initiation Protocol (SIP) is an
application-layer control protocol that can establish, modify and
terminate multimedia sessions or calls. These multimedia sessions
include invitations to both unicast and multicast conferences and
Internet telephony applications. SIP can be used in conjunction with
other call setup and signaling protocols such as ISDN, QSIG, E1 CAS
and T1 RBS in gateway applications.
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.
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 available as a SIP UA SDK in source code
written in ‘C’ for ease of portation.
The CompactSIP User Agent SIP stack is supplied
pre-ported to choice of operating systems including Linux, VxWorks,
Nucleus, ThreadX and Windows. The CompactSIP SIP UA SDK is also
available running on the Freescale Coldfire MCF5234/5 Low Cost VoIP
telephone platform.
CompactSIP User Agent SIP stacks are ideal for
applications such as Gateways, Voice & Video IP Phones, Mobile
Handsets, PC Datacards and PDAs - applications where very small code
sizes and high performance operations are top priorities.
Examples of Systems where the TeleSoft CompactSIP
UA SIP protocol stack is best used:
- Wired SIP Phones - The SIP stack's small code
size and RAM requirements allow you to use less memory and a smaller
processor.
- Wireless SIP Phones - Power management is
important in wireless devices because battery capacity may be
limited. The SIP SDK's low memory requirements mean that you can
use smaller memory, and the quick execution time (i.e. low number of
processor cycles) means that you will be able to increase the idle time
(and put the processor into a power-saving state.)
- Terminal Adapters, Set-top Boxes, SOHO Routers
with analog telephone adapters (ATAs) - These devices generally handle
multiple calls, and usually have two, three or four POTS ports.
The TeleSoft SIP stack's small code size and fast execution time will
allow you to add more functionality and reduce cost by using a slower
processor and less memory.
- VoIP Gateways to the PSTN - Both the smallest
and the largest SIP gateways will benefit from the TeleSoft SIP stack.
TeleSoft also offers TsGATE, an integrated SIP-PSTN gateway solution
that combines the proven TeleSoft PRI & BRI ISDN, QSIG, T1 RBS and
E1 R2 CAS protocol stacks with CompactSIP. TsGATE is an example of
the ways in which we help our customers accelerate their product
developments while reducing costs and minimizing technical risks.
TeleSoft International specializes in the
development of ’Protocols for Developers’ solutions specifically for
OEMs. We supply source code for CompactSIP, Multi-link Frame Relay
(MFR), Frame Relay, DSL, PPPoA, PPPoE, ISDN, Q.931, Q.921, QSIG, ML-PPP,
PPP, T1 RBS, E1 CAS, R2 and X.25 Protocol Stacks for license to
manufacturers of telecommunications products around the world.
TeleSoft provides 'C' Language Source Code Stacks
and Hardware Reference Designs backed up by comprehensive documentation
and expert technical support. TeleSoft solutions accelerate
time-to-market, minimize technology risk, and decrease the cost of both
product development and product maintenance.
