New Revision: 189993

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=189993
Log:
Make chan_h323 respect packetization settings and fix small reload issue.

Previously, packetization settings were ignored and now they are not. A new
config option 'autoframing' has been added to mirror the way chan_sip handles
it. Turning on the autoframing option (available both as a global option or per
peer) overrides the local settings with the remote packetization settings.
Testing was performed with varying packetization levels with the following
codecs: ulaw, alaw, gsm, and g729.

Also, an unrelated config reload issue has been fixed in the case of the config
file not changing.

(closes issue #12415)
