[svn-commits] oej: branch 1.4 r46398 - /branches/1.4/channels/chan_sip.c

[svn-commits at lists.digium.com]

Author: oej
Date: Sun Oct 29 02:45:05 2006
New Revision: 46398

URL: http://svn.digium.com/view/asterisk?rev=46398&view=rev
Log:
Restoring the old logic, since working around it and fixing it seemed too complicated.

- The SIP_OUTGOING flag indicates the direction of the last transaction in the dialog.
- The initreq stores the last request in the dialog, the request that opened the 
  latest transaction.

Please now retry all the 1.4 bug reports with mixed to/from headers, tags etc
in ACK, BYE, CANCEL. Thanks!
