From cacc356bbe211d04a9fea57b6433e0ffa52369df Mon Sep 17 00:00:00 2001 From: Matthew Jordan Date: Fri, 15 Mar 2013 01:38:53 +0000 Subject: When a session timer expires during a T.38 call, re-invite with correct SDP When a session timer expires during a dialog that has re-negotiated to T.38 and Asterisk is the refresher, Asterisk will send a re-INVITE with an SDP containing audio media only. This causes some hilarity with the poor fax session under weigh. This patch corrects that by sending T.38 parameters if we are in the middle of a T.38 session.
