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
