+Subject: [PATCH] channel.c: MOH is not working for transferee after attended
+ transfer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Updated the code to check to see if MOH is playing on the transferor and if
+so then start it on the channel that replaces it during a masquerade.
+
+Example scenario of the problem:
+Alice calls Bob and then Bob begins the attended transfer process into a queue.
+Upon going on hold Alice hears music and so does Bob once he is in the queue.
+Bob then transfers Alice into the queue and then music for Alice stops even
+though she should be hearing it since has now replaced Bob in the queue.
+
+The problem that was occurring is that once the channel was masqueraded the app
+(queues, confbridge, etc...) had no way of knowing that the channel had just
+been swapped out thus it did not start music for the present channel.
+
+Credit to Olle Johansson for pointing me in the right direction on this issue.
