New Revision: 424057
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=424057
Log:
res_pjsip_session: Add additional checks for delaying session refreshes.
There are certain situations which no checks existed for which need to prevent
session refreshes. This includes sending a session refresh with SDP before SDP
negotiation has completed and sending a session refresh before the dialog itself
has been established. Checks for these have been added.
Additionally COLP related UPDATEs were including SDP when it is not needed.
