[asterisk-commits] wdoekes: branch 10 r347167 - in /branches/10: ./ channels/chan_sip.c

[SVN commits to the Asterisk project]

Author: wdoekes
Date: Tue Dec  6 13:42:53 2011
New Revision: 347167

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=347167
Log:
Don't allow transport=tcp when tcpenable=no.

When tcpenable=no, sending to transport=tcp hosts was still allowed.
Resolving the source address wasn't possible and yielded the string
"(null)" in SIP messages. Fixed that and a couple of not-so-correct
log messages.

(closes issue ASTERISK-18837)
