Description:	I am running Asterisk 11.13.1 on a Debian machine. The global nat setting is nat=auto_force_rport,comedia which works quite well. But when I set it to nat=auto_force_rport,auto_comedia so that Asterisk auto-detects if comedia is also supposed to be on, I get one-sided audio.
Comments:	By: Matt Jordan (mjordan) 2015-04-24 12:57:25.085-0500 Thank you for taking the time to report this bug and helping to make Asterisk better. Unfortunately, we cannot work on this bug because your description did not include enough information. Please read over the Asterisk Issue Guidelines [1] which discusses the information necessary for your issue to be resolved and the format that information needs to be in. We would be grateful if you would then provide a more complete description of the problem. At a minimum, we need: 1. The specific steps or actions you took that caused you to encounter the problem. 2. The behavior you expected and the location of documentation that led you to that expectation. 3. The behavior you actually encountered. To demonstrate the issue in detail, please include Asterisk log files generated per the instructions on the wiki [2]. If applicable, please ensure that protocol-level trace debugging is enabled, e.g., 'sip set debug on' if the issue involves chan_sip, and configuration information such as dialplan and channel configuration. Thanks!

You have not demonstrated that Asterisk is doing anything abnormal. Within your scenario (multiple clients behind NAT, Asterisk behind a different NAT on two different networks) there is plenty of opportunity for misconfiguration in both Asterisk, your systems, your clients and your NAT/Firewall devices. If you can provide a very precise way to reproduce this issue then we can investigate it, but right now you have only provided the most minimal description of your scenario. Other than the logs and packet capture, you need to provide the relevant Asterisk configuration files and at least describe your client and NAT/Firewall configurations.

Please request a bug marshal in #asterisk-bugs on the IRC network irc.freenode.net to reopen the issue should you have the additional information requested.
