DAHDI devices support for the Asterisk PBX

 Asterisk is an Open Source PBX and telephony toolkit.
 .
 This package includes the DAHDI channel driver (chan_dahdi.so) and a
 number of other Asterisk modules that require DAHDI support (app_meetme.so,
 res_timing_dahdi.so). They will not be useful without kernel-level DAHDI
 support.
 .
 For more information about the Asterisk PBX, have a look at the Asterisk
 package.
