[SVN commits to the Digium repositories]

Author: mmichelson

New Revision: 148373

URL: http://svn.digium.com/view/asterisk?view=rev&rev=148373
Log:
Make sure that the inUse and inRinging fields for 
a sip peer cannot go below zero. This is a regression
from 1.4 and so it will be applied to 1.6.0 as well.

(closes issue #13668)
