Asterisk Ami Events Stream for NodeJS (ES2015)

Asterisk AMI Events Stream for NodeJS (ES2015)

This is a transform stream for AMI socket. This stream has a three custom events:

This library is a part of Asterisk's AMI Client library.

• amiEvent - fired when event was receive. Handler of this event receives AMI event object.
• amiResponse - fired when response was receive. Handler of this event receives AMI response object.
• amiAction - fired when action was receive. Handler of this event receives AMI action object.

If response from AMI not has structure like this:

<KEY>: <VALUE>CRLF
<KEY>: <VALUE>CRLF
...
<KEY>: <VALUE>CRLFx2

In above case, body of this response will be available in $content property of response object.

asterisk-ami-events-stream's Issues

Session beeing Droped / Disconnected

I was wondering if this is by design or possibly a bug that if there is a certain amount of data coming thru the stream i get disconnected. If the System is idle or i only see phone registrations the system is happy. But as soon as i make a call to system and i get multiple messages like VarSet, Newexten, it closes on a VarSet. There is no error or anything so i am not sure how someone could troubleshot the disconnect.
