From 24a6c9b81509cffe0e8bf09924d1878dd2602e9e Mon Sep 17 00:00:00 2001 From: Matthew Jordan Date: Thu, 29 Dec 2011 15:16:46 +0000 Subject: Handle AST_CONTROL_UPDATE_RTP_PEER frames in local bridge loop Failing to handle AST_CONTROL_UPDATE_RTP_PEER frames in the local bridge loop causes the loop to exit prematurely. This causes a variety of negative side effects, depending on when the loop exits. This patch handles the frame by essentially swallowing the frame in the local loop, as the current channel drivers expect the RTP bridge to handle the frame, and, in the case of the local bridge loop, no additional action is necessary.
