To access the callerid number inside an Asterisk application, you access
it directly on the channel structure.

ast_verbose("The channel cid num is: %s\n", chan->cid.cid_num);

To set it, use the ast_set_callerid() function, which is defined in
include/asterisk/channel.h.  The third argument is for changing the
name, and the fourth is for ANI.

ast_set_callerid(chan, "12564286000", NULL, NULL);

I hope this helps,
