From 0acc6265303822e0c5b4044d8152f38896fdbe83 Mon Sep 17 00:00:00 2001 From: Kinsey Moore Date: Fri, 13 Jun 2014 13:11:38 +0000 Subject: [PATCH] MoH: Don't restart stream on repeated start calls Currently, music on hold will stop and then start again from the beginning if ast_moh_start() is called multiple times. This can happen if a call is put on hold repeatedly (the channel receives multiple HOLD control frames) and can be triggered from ARI by starting MoH on a channel multiple times. This is fairly jarring/annoying to users. This change prevents MoH from being restarted if the requested music class is the same as the one currently playing.
