If you are on a PRI, there is no time penalty in call setup to send the
entire phone number. In fact, it is beneficial to have the full number
as it reduces conflicts later on if you ever want to add numbers. Not to
mention you will make your telco provider much happier if they don't
have to come up with consecutive phone numbers but rather can pull from
any current gaps and possibly across exchange numbers. 

If you are on an E&M Wink where the number is transmitted via DTMF or
MF, you will find a time penalty for each digit transmitted and
therefore you will want to keep the number of digits low. OF course if
you are choosing E&M wink, it is possible you aren't wanting to use any
of the advance features of the PRI and/or are hamstrung by some other
limitation outside of asterisk.
