Here is an example..

On Asterisk 13, sending the command:
{quote}{code}Action  : Command
command : sip show channels{code}{quote}

Would result in:
{quote}{code}UnformattedResponse : True
line3               : --END COMMAND--
line2               : 1 active SIP dialog
line1               : 192.168.161.100  (None)           57aa6af119aeed9  (nothing)        No       Rx: OPTIONS                <guest>
line0               : Peer             User/ANR         Call ID          Format           Hold     Last Message    Expiry     Peer 
ActionID            : 3
Privilege           : Command 
Response            : Follows{code}{quote}

But on Asterisk 14, sending the same command results in;
{quote}{code}Output   : 1 active SIP dialog
Message  : Command output follows
Response : Success
ActionID : 3{code}{quote}

>         Environment: CentOS 6.8

> The AMI Action 'Command' only returns the last line from the output of a CLI command.
> This is the case since the launch of Asterisk 14, which is described on the Asterisk Wiki as;
> "The Command action now sends the output from the CLI command as a series of Output headers for each line instead of as a block of text with the --END COMMAND-- delimiter to match the output from other actions."
> https://wiki.asterisk.org/wiki/display/AST/Upgrading+to+Asterisk+14
> As a result we are no longer getting a useful response if the CLI command executed contains multiple lines, like 'core show channels' or 'sip show channels'
> In these cases only the last line of the CLI Command is then reported on the "Output header" 
> The WiKi mentions; "a series of Output headers for each line"
> But clearly that doesn't happen, we only get a single "output header".
> I've written a simple patch that reverts this change.
> Even though this works for me at the moment, reverting the change is a step backwards and likely not the correct way to continue.
> I'd like to write a correct solution to the problem, but this requires me to know more about the reasons behind the original change.
> However, I could not find the actual change anywhere in the ChangeLog or here on Jira. 
> Some assistance is appreciated.
