Jessie Kid Fernando commented on ASTERISK-28143:
------------------------------------------------

Just for the record. This is the version I am using.  And this is the app_amd.c that I am using when compiling the entire system. Let me know if this is correct or not. The source file (asterisk-13.27.0.tar.gz) was from https://downloads.asterisk.org/pub/telephony/asterisk/old-releases/.

> 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 .
