Subject: chan_iax2.c: Don't send unsanitized data to the logger.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da4e6e7ddb679904bc55d06b2328c842407a4219;p=thirdparty%2Fasterisk.git

chan_iax2.c: Don't send unsanitized data to the logger.

This resolves an issue where non-printable characters could be sent to
the console/log files.
