SIP-POTS Gateway Software -- "C" Source Code

 

SIP-POTS Software for Signaling Interworking

TeleSoft International provides SIP-POTS signaling interlocking, which includes TeleSoft's Embedded SIP source code software, in order to accelerate development and interoperability testing of your gateway or similar product. TeleSoft's gateway provides the fastest path to market-ready telephony products for manufacturers worldwide.

TsGATE is an integrated software SIP to Plain Old Telephone Service (POTS) Gateway software design kit that translates the packetized signaling messages on IP networks to an easy to use API for analog (POTS) telephones.  TsGATE is an ideal solution for OEMs developing embedded gateways and adapters since the TsGATE Soft Gateway is hardware and RTOS independent and can be ported to a wide variety of platforms to create IP to TDM conversion products.

SIP-POTS Signaling Interworking applications

TsGATE Soft Gateway is ideal for for cost and memory sensitive applications, from a desktop terminal adapter to the largest system. 

Small Gateway SIP-PSTN applications:

The small RAM and ROM footprint of the Compact SIP software development toolkit means that you can save memory.  And the fast execution speed allows use of a slower processor;  fewer instruction cycles means that the processor can "sleep" more thereby lowering power requirements. 

 These devices may VoIP-enable a standard POTS  telephone, or may allow a local VoIP phone or softphone to access the local PSTN.  Even if a customer has a VoIP phone connected to a VoIP phone provider, they may desire some calls to go to the local PSTN because of quality or network congestion issues (i.e. "best quality routing"), and the customers may desire that all emergency "911" type calls go via PSTN instead of VoIP.

  • Residential Gateways
  • Terminal Adapters
  • VoIP enabled Home and SOHO Routers
  • IP PBX to legacy PBX Protocol Adapters
  • IP-PSTN Key Systems

Large Gateway SIP-POTS applications:

The low per-call memory requirement of Compact SIP means that you can save a significant amount of memory when your gateway services thousands and tens of thousands of calls.  And the fast execution time results in more calls per MIPS, or in lower power requirements for a given number of calls.  This translates into lower power requirements for your system, less heat generated by the processor, lower air conditioning requirements--in short, better NEBS performance.

These devices may VoIP-enable a standard PBX, or allow a network of VoIP phones and VoIP softphones connected to an IP PBX or router to interwork calls to the PSTN.   Even if a customer has an internal VoIP network connected to a VoIP service provider, they may desire some calls to go to the local PSTN because of quality or network congestion issues ("best quality routing") or for cost reasons ("lease cost routing" and "toll bypass").  Also, customers may desire that all emergency "911" type calls go via a local PSTN rather than their VoIP service provider.

  • Medium and Large Enterprise Gateways
  • Telco/VoIP Gateways
  • Hybrid PBXs
  • VoIP service providers
  • "IP Channel Bank" or Media Gateway
    • save wiring and maintenance costs by connecting remote phones over an IP connection
    • within building, within campus, in different countries, ...

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 protocol software development toolkits (SDKs) offer highly optimized protocol stack solutions that combines very small memory footprints with high performance and no compromises on functionality and scalability. All TeleSoft SDKs are supplied in source code written in ‘C’ for ease of portation.

Telecom and VoIP have needs that are different than data communications, and the industry is just realizing how different VoIP is from datacom.   Telecom protocols are required to be robust, and if VoIP is to be widely accepted, it must be as robust as the existing PSTN.  Doesn't it make sense to license your Voice over IP (VoIP) signaling protocol from the voice experts?

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.
