Subject: chan_iax2.c: Ensure all IEs are displayed when dumping frame contents.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19507ae160f796363a7332276c5d5628e2e84b0e;p=thirdparty%2Fasterisk.git

chan_iax2.c: Ensure all IEs are displayed when dumping frame contents.

When IAX2 debugging was enabled (`iax2 set debug on`), if the last IE
in a frame was one that may not have any data - such as the CALLTOKEN
IE in an NEW request - it was not getting displayed.
