I need to integrate a framer driver with Asterisk for an embedded system project. I am aware that DAHDI is the official way to work with some PCI digital interface cards and think this driver porting task might as well go in this direction.
Questions:
- Is there a developer’s guide available for working with DAHDI?
- If the driver comes with both kernel and user layers to handle the PRI signaling and B-channel voice data, what is the proper approach for the solution? porting the chan_dahdi to fit these non-DAHDI layers?
Thanks.
