[Freeswitch-users] originating a call from an outbound socket app

Fri Jun 10 18:00:02 MSD 2011

Thanks for your response Michael.

Finally I found the way of dialing to an external extension. What I did was just open a shell, listen in a port using nc  and tried to originate a call. It worked using the syntax:

originate sofia/internal/5562 at 192.168.23.104 &park

As this is an outbound call (not managed by the socket application) I had to use a new inbound socket connection to connect to FS, make the call, query for the uuid and receive some events (like DTMF among others).  Everything was going great, until I found two issues:

-          The CHANNEL_ANSWER event is always triggered, no matter if the call is actually picked up or not on my phone. I thought that maybe I can use some other event to determine if the call have been answered or not (like CHANNEL_CALLSTATE or CALL_UPDATE), but the additional information on the event headers is the same no matter if it's answered or not.

-          When the call is answered, and the user presses a key to accept the call, the function returns the UUID of this session to the main method. Then I tried to make the bridge between the two calls (the legA call handled by the socket application, and the legB outbound call generated in the application using an inbound connection). I using the command

api uuid_bridge <incoming_uuid> <outbound_uuid>

but this didn't work. Am I missing something here?

Thanks again,
Hector

Also, I don't think this is helping you:
  EslMessage response = sendSyncSingleLineCommand(channel, "myevents");

Look here to see what "myevents" does:

Hi Michael,

Thanks for replying back. I've pasted a sample application on pastebin, the URL is:

http://pastebin.com/MYusWe3V

What I'm trying to do (and have partially accomplished) is:

-Answer the call
- Play a message
- wait for a command (dtmf or voice, this is out of the sample app for the sake of keeping it short & simple)
- originate a new call, wait for it to be answered and depending on an event (dtmf)...
- ...do the bridge or dial another extension.

The extension number is external (managed by a Cisco CCM). If I try to do the bridge from the XML dialplan it works perfect. When I try to do it from an outbound socket java application, anything happens, and almost no information is logged on FS log that I can use to decide what might be happening.

Thanks again for your help. I truly appreciate it.

I would say that you want to bridge the inbound leg to the outbound leg and use the answer confirmation variables. I recommend you pastebin a simple java app that answers the call and attempts to bridge it and also pastebin the console log. The community will take a look and see if we can help you figure out what is happening.

Hi all,

I've been playing with FS around weeks, with some level of success. Right now I'm stuck trying to dial an extension, or to bridge a call to an external extension. Briefly, the scenario is the following:

-          Cisco CCM forwarding SIP calls to FS

-          FS in outbound mode,  forwarding calls to a Java application using freeswitch-esl jar

The java application answers the call, says a dialogue using TTS and receives input using DTFM or speech commands; all this is working pretty well. Now I'm trying to put this call in hold, originate a call to another extension and, depending on the result (call answered, not answered, destination user presses an specific number generating an expected DTMF), I need to bridge both calls and finish the session.

I try several ways to get this done with no luck yet: using api originate to make the call with different arguments ({ignore_early_media,  etc). I even tried to skip this step and just do the bridge between the inbound call and the external extension, but this  didn't work either. I can't see any errors thrown by FS, and the result of the command is +OK, but nothing happens, the external phone never rings. The FS log only says:

[DEBUG] switch_core_session.c:954 Send signal sofia/external/5655 at 192.168.8.1<mailto:5655 at 192.168.8.1> [BREAK] <= this ext/IP address is from the inbound caller, not the one I'm trying to connect to.

My first impression was that I might have something wrong with the originate/bridge parameters. I changed the dialplan XML file to just do the bridge, and it worked like a charm.

<include>
<extension name="test">
        <condition field="destination_number" expression="6114|5121">
<!--    <action application="socket" data="localhost:8044 async full"/>  -->
          <action application="bridge" data="sofia/external/5562 at 192.168.2.14<mailto:5562 at 192.168.2.14>" />
        </condition>
</extension>
</include>

I don't know what path to follow here. I was unable to find relevant examples on google that guides me to solve this little issue. Any advices?

Thanks all,
Hector
