    [ https://issues.asterisk.org/jira/browse/ASTERISK-20158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=195907#comment-195907 ] 

Kaloyan Kovachev commented on ASTERISK-20158:
---------------------------------------------

 As stated in the review, this is a bug on my opinion, because 'we get stuck on the alarm receiver app until it times out'
 This also applies for a malicious caller who can block the line for a long time (will open another issue), but the complete fix will require adding a config or application option to timeout if no valid events are received for some time or the call keeps going too long even with valid events.
 I think the best will be to add application options as it will not break old dialplans, but will allow the user to set different values for whitelisted panels, that send lots of events (call_timeout) or 'known broken' panels that have problems sending dtmf (no_event_timeout).

> Some alarm panels have support for opening a voice channel after sending the alarm data. This patch add support for this. 
> Currently the alarm receiver app is waiting for the remote site to hangup, this kind of alarm panels never hangup, and we get stuck on the alarm receiver app until it times out.
