Re: [Asterisk-java-users] Listen for an incomming call to a sip/extension

[Zoumana T. <zou...@gm...>]

Hi Jorge,

Not tested but maybe you can do something like

String targetExtension = "SIP/100";
        Collection<AsteriskChannel> activeChannels =
asteriskServer.getChannels();
        boolean targetIsActive = false;
        String otherPartChannel = "";
        for (AsteriskChannel activeChannel : activeChannels) {
            String callerChannel = activeChannel.getName();
            if(callerChannel.contains(targetExtension+"-")){ //i suggest to
add this because Asterisk always set channelName like "SIP/100-000001"
                //if you don't maybe you will match the Channel SIP/1000
for example if it exists
                targetIsActive = true;
            }
            String calledChannel = "";

            //regarding the API getDialedChannel, getDialingChannel,
getLinkedChannel seem to be interesting, but i can't figure out exactly THE
ONE IS RIGHT FOR YOUR NEED
            if(activeChannel.getDialedChannel() != null){
                calledChannel = activeChannel.getDialedChannel().getName();
                if(calledChannel.contains(targetExtension+"-")){
                    otherPartChannel = calledChannel;
                }
            }else if(activeChannel.getDialingChannel() != null){
                calledChannel = activeChannel.getDialedChannel().getName();
                if(calledChannel.contains(targetExtension+"-")){
                    otherPartChannel = calledChannel;
                }
            }else if(activeChannel.getLinkedChannel() != null){
                calledChannel = activeChannel.getDialedChannel().getName();
                if(calledChannel.contains(targetExtension+"-")){
                    otherPartChannel = calledChannel;
                }
            }
        }

Hope this will help.

Regards,
Zoumana
