[asterisk-commits] mmichelson: branch 1.4 r114632 - /branches/1.4/channels/chan_sip.c

[SVN commits to the Asterisk project]

Author: mmichelson
Date: Thu Apr 24 16:35:08 2008
New Revision: 114632

URL: http://svn.digium.com/view/asterisk?view=rev&rev=114632
Log:
Re-invite RTP during a masquerade so that, for instance, an AMI
redirect of two channels which are natively bridged will preserve audio
on both channels. This prevents a problem with Asterisk not re-inviting
due to one of the channels having being a zombie.

(closes issue #12513)
