[Freeswitch-users] answer via .net esl is getting ignored

"if you want to control an incoming call (a call that hits an extension
managed by freeswitch) you'll be better served by using a socket outbound
connection. Off course this is from a design perspective, not because there
are limitations when using an inbound connection."

Is he wrong?

Is there any documentation this way or the other?

Changing to outbound is really a last resort, as this would disallow me to
just connect to any arbitrary freeswitch instance at will

But rather requires freeswitch having precise knowledge of my application

While im considering outbound, I see that I have in my event_socket file:

<configuration name="event_socket.conf" description="Socket Client">

  <settings>

    <param name="nat-map" value="false"/>

    <param name="listen-ip" value="0.0.0.0"/>

    <param name="listen-port" value="8021"/>

    <param name="password" value="mypass"/>

    <!-- <param name="apply-inbound-acl" value="lan"/> -->

  </settings>

</configuration>

Could this be confusing freeswitch to think I'm using outbound?

Thanks!

If you are trying to handle incoming calls you probably will have to use
outbound socket, otherwise Freeswitch will  finish running the dialplan and
hangup before your ESL client has a chance to send it any commands. As you
can see from the log there are no dialplan matches found so FS responds with
a 480. When using outbound mode you put the socket app in the dialplan so
that FS knows to hand over the call handling to your ESL client.

Hi

Thanks fellows

Sorry for the delay, we were a bit busy here lately

I'm attaching the fs log. I don't even see a the word "answer" there. 

It seems fs is totally ignoring the incoming commands

if there's a way to use inbound (which should be according to the docs) I'd
rather not switch around the whole architecture just right now

If there won't be any other choice, I guess I'll try that

Thank again

Try using ESL Outbound mode, I am not sure why it would make a difference,
but I have recently used outbound mode and I was able to answer the call.
See the mod_event_socket wiki page and the sample code in the managed_esl
project for more information.

Hello everyone

This is my first posting via the mailing list

I'm trying my hand at freeswitch esl with .net

I've managed to get a hold of all incoming events, but can't seem to "pick
up the phone"

my first goal is to pick up the phone and read out some text via tts

I've scoured the web, tried everything I can find or think of but no luck

here's my code

    Private Sub winMain_Loaded(sender As Object, e As RoutedEventArgs)
Handles Me.Loaded

        ThreadPool.QueueUserWorkItem(New WaitCallback(Sub(stateInfo)

                                                          FreeSwitch = New
ESLconnection("10.0.0.1", 8021, "mypass")

                                                          Dim eslEvent =
FreeSwitch.SendRecv("event plain ALL")

FreeSwitch.SendRecv("event plain DTMF")

                                                          If eslEvent IsNot
Nothing Then

AddEvent(eslEvent)

                                                              While
FreeSwitch.Connected

                                                                  eslEvent =
FreeSwitch.RecvEvent

AddEvent(eslEvent)

                                                              End While

                                                          End If

                                                      End Sub))

    End Sub

    Private Sub AddEvent(e As ESLevent)

        Dim dd = TextCollection(e.Serialize(""), ": ", vbLf)

        Dim eventname = dd("event-name")

        'Dim uid = dd("Unique-ID")

        Dim uid = dd("Channel-Call-UUID")

        If dd("Caller-Network-Addr") <> "" Then

            Dim dcx = DBEntities()

            Dim ses = dcx.Sessions.SingleOrDefault(Function(x) x.ServerCode
= uid)

            Dim ChannelState = dd("Channel-State")

            Dim ChannelCallState = dd("Channel-Call-State").ToLower

            Select Case eventname

                Case "CHANNEL_STATE"

                    If ses Is Nothing Then

                        ses = New Session

                        dcx.Sessions.AddObject(ses)

                    End If

                    ses.CallerHost = dd("Caller-Network-Addr")

                    ses.CallerName = UrlDecoded(dd("Caller-Caller-ID-Name"))

                    ses.CallerPhone = dd("Caller-Caller-ID-Number")

                    ses.CallerUser = dd("Caller-Username")

                    ses.CalleeUser = dd("Caller-Destination-Number")

                    ses.ServerCode = uid

                    If {"cs_destroy", "cs_hangup"}.Contains(ChannelState)
Then ses.HungUpOn = Now

                Case "CHANNEL_CALLSTATE"

                    If ChannelCallState = "ringing" Then

                        Dim evn = FreeSwitch.Execute("answer", String.Empty,
uid)

                        Dim res = evn.Serialize("")

                    End If

                Case "CHANNEL_DESTROY"

                    If ses IsNot Nothing Then ses.HungUpOn = Now

            End Select

            dcx.SaveChanges()

        End If

    End Sub

the answer line is getting reached, and the result is "+OK" but the phone
still keeps ringing

please note that I'm unsure which is the correct uuid, but trying both of
them gave me identical results

As per advise from Nuwan Wijerathne, I put the "answer" action in the
dialplan, and tried just the playback from code (just a wav file), but the
result is the same. Freeswitch ignores entirely my commands.

It picks up, and immediately hangs up because it has finished the whole
dialplan

I'd appreciate your help. I'm pretty new to freeswitch and esl

Please advise

Sincerely,

ymo
