I installed the Zaptel drivers after the board could not recognized by Elastix. I followed instructions on an Asterisk book I purchased calling for Zaptel drivers. I did not know that the board would work with DAHDI. However, the DAHDI drivers are installed. Is there a conflict between the Zaptel and DAHDI drivers?
A very a big one. you need to remove everything that got installed for ZAPTEL.
When you have DAHDI installed again, dahdi_genconf usually finds your hardware, but will show the problems(or lack of), when run, dahdi_scan will show what is configured, dahdi_tool will show the state of the channels.
/etc/init.d/dahdi start (or stop)
will let you see any problems when starting or stopping the service
