Thank you again. Works great now.

Thanks for your help, I got it to work with FOP2Callbacks.pm (didn't manage to send any events from plugin).
I have some problems with substitutions in the popup link though. Only #{CLIDNUM} and #{CLIDNAME} work, both #{UNIQUEID} and #{EXTEN} substitute undefined.

WIP code for Asterisk 13 and FOP2 2.29 (wasn't tested thoroughly):

#. . .
sub __prep_chan {
	my $chan = shift(@_);
	
	$chan =~ s/^(.*)-.*/$1/;
	$chan = uc($chan);
	
	return $chan;
}

sub amiCommand {

	# Received an event from Asterisk Manager Interfase

	$command  = shift;

	if($command eq "DIALEND") {
		%event = @_;
		if($event{'DialStatus'} eq 'ANSWER') {
			my $dst_chan = __prep_chan($event{'DestChannel'});
			my $src_chan = __prep_chan($event{'Channel'});
			my $uid = $event{'Uniqueid'};
			
			my $return = "";
			my @allreturn = ();
			
			$return = "Action: UserEvent\r\n";
			$return .= "UserEvent: CustomPopup\r\n";
			$return .= "Uniqueid: $uid\r\n";
			$return .= "Channel: $dst_chan\r\n";
			$return .= "Family: notifyconnect\r\n";
			$return .= "Value: $src_chan\r\n";
			$return .= "\r\n";
			
			push @allreturn, $return;
			return @allreturn;
		}
	}

Hello.

I'm trying to make FOP2 chrome app to open URL upon answering any call (not just queue calls) with FOP2Callbacks.pm. I see that FOP2Callbacks.pm is mostly aimed at executing AMI actions, is it possible to send events to connected users from FOP2Callbacks.pm ?
What I'm aiming for is making fop2_server to send notification to client on receiving the BridgeEnter event (like it does on receiving the AgentConnect event).
