Currently there are some buildtime configuration parameters:

To build the driver you will need an installed capi system, including header

CAPI command application
========================
chan_capi provides an additional Asterisk application
capicommand()
With this application, special capi commands and features can be used.
Call Deflection:
Forwards an unanswered call to another number.
Example:
exten => s,1,capicommand(deflect|12345678)
Helper applications
===================
Kapejod says: "No No No, don't use those yet....!" (except maybe HOLD,ECT...)
app_capiCD.c
Forwards an unanswered call to another phone (does not rely on sservice CD)
Example:
exten => s,1,Wait,1
exten => s,2,capiCD,12345678
app_capiHOLD.c
Puts an answered call on hold, this has nothing to do with asterisk's onhold
thingie (music et al)
