[svn-commits] russell: branch 1.4 r58705 - /branches/1.4/channels/chan_iax2.c

[svn-commits at lists.digium.com]

Author: russell
Date: Sat Mar 10 12:11:11 2007
New Revision: 58705

URL: http://svn.digium.com/view/asterisk?view=rev&rev=58705
Log:
Fix a few more places in chan_iax2 where the ast_frame used for receiving a
frame was not properly initialized.
 - Interpolating a frame when the jitterbuffer is in use
 - decrypting a frame when IAX2 encryption is on
 - frames in an IAX2 trunk
