LibSangoma- API Documentation


    LibSangoma proves OS abstraction to Wanpipe Driver Voice & Data API system calls.  It contains all Wanpipe Driver Voice & Data API functions, abstracted for Linux & Windows so that user application remains OS independent.

    LibSangoma Components

    • Configuration Functions
      configure T1/E1, analog, BRI ports before they are started or restarted
    • System Operation Functions
      used to start, stop, restart Sangoma tdm ports
    • IO Operation Functions
      used to open, close, read, write,poll on bchan or dchan devices
      set events that relate to IO or call setup
      callerid, on-hook, off-hook, rbs etc…
    • Event Functions
      used to read events from bchan or dchan devices.
      Used to enable or disable hw events (DTMF, Fax events …)
    • Statistic Functions
      used to read hw and driver statistics.
      Operational, Hardware, Error, IO, statistics

     

    LibSangoma IO Componnets

    • SPAN Mode
      Single device per T1/E1 span.
      Data from a single span is passed up to a user as a single chunk of data.
      User has the responsibility to multiplex and de-multiplex data per channel.
      Better performance on higher densities.
      Harder to develop on.
    • CHAN mode
      Device per T1/E1 channel
      Highly efficient interrupt logic to minimize number of interrupts.
      High kernel context switching due to large number of devices.
      Easer to develop on. Easily fits into a multi-thread applications.
      Default behavior for Zaptel/DAHDI, FreeSWITCH, SMG
