WANPIPEŽ Linux & Windows TDM Voice API


WANPIPE® TDM Voice API is a device based, multi-threaded suite of kernel drivers and user space libraries that can be used to build custom Voice applications over TDM Voice hardware, on both Linux & Windows.

The WANPIPE® TDM Voice API has been designed to fit easily into a network programming model. Therefore anyone who has ever done any socket programming will feel right at home. Thanks to the socket API model, a channel on a particular span is just a file descriptor that can be used to transmit and received voice data. Along with standard rx/tx, a tdm device also support OOB messages that become useful in DTMF detection and RBS signaling. Standard IOCTL calls are use to control channel socket parameters such as rx/tx period, codec control, echo control, rbs and dtmf.

WANPIPE® TDM Voice API is supported on Linux & WIndows.  Furthermore all sample codes are identical for all operating systems.

 

Sangoma Wanpipe TDM API Architecture:


Sangoma Wanpipe TDM API



Sangoma Wanpipe TDM API Provides:

  • Support for Linux & Windows operating systems.  
  • Common API for all Sangoma Hardware (T1/E1/Analog/BRI).
  • Extensive Support for TDM Voice Applications
  • SPAN API Mode  -  one device per span (TDM Voice or WAN Data)
  • CHAN API Mode -  one device per chan  (TDM Voice Only)  
  • Timer Devices used for Timing
  • Global Config Device used to configure/control/debug.
  • Global Control Device receives all events from all devices.
  • LibSangoma (Library/DLL) - Abstracts all OS API calls.

Sangoma Wanpipe TDM API Components:

  • Wanpipe Kernel Driver & Utilities - Common for Linux & Windows
  • LibSangoma API Library/DLL
    -  libsangoma is a low level Device/Ioctl based API.
    -  libsangoma provieds: read/write/events/configuration/managment routines.
    -  libsangoma API is 100% identical for Linux & Windows.
    -  libsangoma works for all Sangoma AFT series cards.
    -  One sample code for Linux & Windows
    -  libsangoma does not include high level signaling stacks (PRI/BRI etc..)

 

 

More documentation coming soon....
