Errors
If the function returns < 0 to indicate failure, use the cc_CauseValue( ) function
to retrieve the reason code for the failure. The cc_ResultMsg( ) function can be
used to interpret the reason code. Error codes are defined in the files ccerr.h,
isdnerr.h, and isdncmd.h.
Error codes from the cc_ReleaseCall( ) function include the following:
