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!

I can understand how this may be critical to you, but I've put it back to where I feel it fits as a project which is major.

what else can i do to speed up the solution ?
By: Joshua C. Colp (jcolp) 2016-07-08 05:16:06.469-0500

You can try to find a consultant who will fix the issue, but they will likely charge money. The asterisk-biz list can be used for this. You can also post a bounty[1] but the minimum is $500.
