dialtest

DIALTEST(8)						      System Manager's Manual						       DIALTEST(8)

NAME

       dialtest - HylaFAX dial string processing rules test program

SYNOPSIS

       /usr/sbin/dialtest [ options ] dialrules

DESCRIPTION

       dialtest  is  an  interactive  program for the testing and development of dial string processing rules used by HylaFAX.	dialtest reads the
       file of rules specified on the command line and then prompts for a dial string.	For each string typed in, dialtest prints  the	result	of
       applying  the  canonicalization	and dial-string preparation rule sets.	A rule set whose name is setname can be specified by typing ``set-
       name(string)''; for example, ``CanonicalName(+1.415.965.7824)''.

       Note that dialtest reads the rules file only when it is initially started up.  This means that dialtest must be restarted for it  to  apply
       changes to a rules file.

OPTIONS

       -a code	 Use code as the value of AreaCode in the rules file.  The default area code is ``415''.

       -c code	 Use code as the value of CountryCode in the rules file.  The default country code is ``1''.

       -i prefix Use prefix as the value of InternationalPrefix in the rules file.  The default international dialing prefix is ``011''.

       -l prefix Use prefix as the value of LongDistancePrefix in the rules file.  The default long distance dialing prefix is ``1''.

       -q	 Be quiet, suppressing most all output except for the actual results.  This is useful for using dialtest in an automated fashion.

       -v	 Print	each  input line before displaying the results of applying the dial string rules to the input string.  This can be useful,
		 for example, in shell scripts.
