> Components: Applications/app_amd
> Affects Versions: 15.6.1
> Environment: Ubuntu with asterisk
> Reporter: Abhay Gupta
> Assignee: Abhay Gupta
> Labels: patch
> Target Release: 13.27.0, 16.4.0, 17.0.0
>
> Attachments: amd.patch
>
>
> On our production server , some of the calls never return from AMD application , from logs we could see that they have last gone into AMD() of dialplan and comes out only when the call is HANGUP .
> The suggested patch is to remove that infinite loop and has been tested for last few months and have been working well .
