I have need of a very simple command line Linux application which MUST accomplish:
Open an [url removed, login to view] listener on a configurable port
On an incoming call attempt immediately return cause 34 (no circuit/channel available) to disconnect the attempt; Progress or Alerting must not be returned.
Be capable of handling more than one simultaneous call attempt.
Other desirable, but NOT ESSENTIAL features:
Written using OPAL API so I stand a chance of learning something too :-) ([url removed, login to view])
If the code can be easily generalised to work for SIP calls too, that would be nice.
This project may possibly be quickly and easily accomplished by modifications to an existing soft phone, ohphone, in the OPAL samples folder; a simple one-line change does almost what I want. My C++ sucks too hard to get much further.
I think that I can do this task. May be I'll complete faster.
