Description:	When bridging two calls after one has been put on hold, the called person hears both music on hold along with the original callers voice. This is occurring more often than not. After several tests we are seeing 5 out of 7 calls "failing" whereby music on hold is not released when the called party has answered. h5. Steps to Reproduce This is difficult to reliably reproduce. We have tried this over 3 different carriers, trying with either IAX or SIP and the problem still persists. h5. Additional Information I've not classified this problem as I'm not too sure where the issue lies. I'm assuming, for the moment, that it may be related to music on hold. I've attached 2 messages files one of a working call and one of a "failed" call, where the music on hold is not released. The messages files contain the following output: * core set verbose 10 * core set debug 10 * sip set debug on I have tried this with Asterisk version 1.6.2.13 standalone, and with asterisk version 1.6.2.13 with the patch from ASTERISK-16583 applied.
Comments:	By: Bruce McAlister (asgaroth) 2010-10-20 08:31:36 This issue also presents itself with v1.8.0-rc5 on Solaris. I will be testing this on Linux (v1.8.0-rc5) shortly to see if it us a Solaris specific issue. By: Bruce McAlister (asgaroth) 2010-10-20 15:55:27 I've just attempted this on CentOS 5.5 with asterisk 1.6.2.13 and the issue still presents itself By: Bruce McAlister (asgaroth) 2010-10-20 16:26:58 I've attached a sip trace of one working call and one failed call if that will help try to track down where the issue lies. By: Leif Madsen (lmadsen) 2010-10-29 09:05:25 I dropped this to minor because I thought it was just solaris, but if you're getting this with linux as well, I'll leave it at the major you originally had it set to. By: Bruce McAlister (asgaroth) 2010-10-29 09:15:02 Thats correct yes, the versions tested thus far are: 1.8.0-rc5 on Solaris 10 32-bit 1.8.0-rc5 on CentOS 5.5 64-bit 1.8.0 on Solaris 10 32-bit 1.8.0 on CentOS 5.5 64-bit 1.6.2.13 on CentOS 5.5 64-bit 1.6.2.13 on Solaris 10 32-bit All the above variants exhibit the same problem. It is intermittent and difficult to track any difference in the calls. The SIP traces I have above are one successfull call and on failed call. The traces are taken from a 1.6.2.13 server running on CentOS 5.5 64-bit. By: Bruce McAlister (asgaroth) 2010-11-30 05:09:33.000-0600 Hi, any recommendations on how to proceed with this bug? By: André Emerich (aemerich) 2012-11-21 10:01:57.159-0600 I have the same problem on Linux. When the called party answer, I hear it and the Music On Hold at same time..

By: Sean Bright (seanbright) 2021-09-28 13:29:22.145-0500 If you can reproduce on a supported version of Asterisk, commenting on this issue will re-open it. Thank you.
