Then you have two alternatives:
1) External port program
2) Multithreaded linked in driver with a separate wait thread

   handling the board communication.

We had similiar problems, but as I said this was ages ago.

I have implemented erlang interfaces for Aculab, NMS and Dialogic
In my opinion Dialogic (now Intel) was the best vendor but that was
absolutely not without flaws. It is possible to write a linked in
driver for dialogic (but one need to find the multiplex fd by

My favourite nowadays for CT is Corelatus (
and their GTH box. It is great stuff if you roll your own call control
(or use third party).
