New Revision: 1394
URL: http://svn.digium.com/view/zaptel?rev=1394&view=rev
Log:
* Re-add calibrate_slics to the FXS initialization process
* xpp/utils: Build and install init_fxo_modes . Data is based on data from
wctdm.c . TODO: a separate daa.h?
* Fail the script if automatic calibration has failed.
Added:
