Telephony Cards for API

Event based sdk that allows full leverage and power of Sangoma signaling and voice stacks.

Integrated signaling, voice, tone events and I/O

Higher level API:  place call, clear call, read data

For: MTP2 API, FXO/FXS tapping, ISUP tapping and ISDN Tapping

Supported Telephony cards: A10X, A116, a200, a400 

Supported signaling types: PRI, BRI (roadmap), SS7, FXO, FXS, GSM 

Supported OS: Windows and Linux

Data API For Sangoma A101,A102,A104, A108 (E1/T1) and A142/A144 telephony Cards

Modes of operation

• HDLC: The sample application runs on top of a hdlc interface and receives HDLC formated frames.
  HDLC framing is done in AFT hardware.

• Transparent (Bitstreaming) Mode: The sample application runs on top of a raw transparent interface and
  receives all bits on the line in configurable block size.
  HDLC framing is turned off in hardware

• Protocol API Mode: The AFT API can run on top of a protocol interface such as: PPP, CHDLC, ATM, Frame Relay.
  Support For S518 ADSL, Multilink PPP, PPPoE over ADSL  

Voice API used to build custom Voice applications over Sangoma telephony cards,on both
Linux & Windows

Provides raw HDLC (dchan) framing, and raw ulaw/alaw (bchan) I/O

Customer application is responsible for signalling protocols and higher layer functions

Can be used for both network termination or tapping

Supported on all Sangoma Telephony cards
 

NOTE: The FreeTDM API is provided strictly AS-IS, with no support from Sangoma.

It is an API for the FreeTDM project

It is intended for custom development along with TDM and analog telephony cards

The FreeTDM API allows you to configure spans and run a given signaling stack on a span

The intention of the library is to present a consistent API for different telephony signaling stacks and board I/O APIs
