New Revision: 99652
URL: http://svn.digium.com/view/asterisk?view=rev&rev=99652
Log:
Thanks to Russell's education I realize that BUFSIZ has changed since I learned the C language
over 20 years ago... Resetting chan_sip to the size of BUFSIZ that I expected in my old
head to avoid to heavy memory allocations on some systems.
