You don't need to invoke it, you connect to fs permanently and subscribe to the events you're interested in. When you get the events, you can get all the info you want and act accordingly.

Hi David,

Thank you for the answer. In the perl script I need to do some logic to detect the event and send a notify back to the event system. So my concern is how I make freeswitch invokes the perl script in my dialplan where I have already a bridge application?

Regards

Hello,

Why not connect to fs via perl esl and filter the events? (Inbound) you remove the overhead of creating a new connection everytime a call is executed...
you'd connect to fs from perl and keep the connection open.

I understood now, when invoking socket with async, it should start a new thread and continue to next step bridging the call.

Well, I have never tried such thing before, I will do some testing and when I get any result I return to you.

Dear Valtar,

Thank you for your answer.

Yes I am using ESL bind for perl.

When you are using <action application="socket" data="127.0.0.1:8084 async"/> it means you are in outbound mode (from the perspective of FS)

Are you using ESL bind for perl or have you written your own implementation?

After accepting a connection on 8084 port, you should issue a "connect\n\n" back to FS

Hi Guys,

I guess I have a little confusion here between inbound esl and outbound esl.

My Goal: What I am trying to do is detect if the call is being transferred and notify the caller about it.

My Scenario:

1- I have an application based on SIP.js client that makes outbound calls via a registered SIP trunk on my Freeswitch box. I upload a list of phone numbers to call and hit Launch button.

2- Some calls can be transferred by the callee endpoint. I want to detect this fact.

3- According to my research, I can do this using Event Socket library.
4- To detect if there is a transfer, I can control the channel variable RDNIS or TRANSFER_TIME. If there is a transfer these variables are not empty.
5- Once I detect there is a transfer I want to send a NOTIFY packet to the client.

My confusion is the following:

I don't know whether to use an Outbound socket connection or an Inbound Connection.

I tried to do this with outbound connection as follows:

<condition field="destination_number" expression="^1703$">
    <action application="set" data="socket_resume=true"/>
    <action application="socket" data="127.0.0.1:8084 async"/> 
    <action application="bridge" data="sofia/gateway/mygateway/$1"/>
</condition>

I have a perl server listening on port 8084/tcp.
In this perl script I subscribe for CHANNEL_ANSWER Events and I filter by the call uuid.

The problem is when I call the socket connection, the bridge application never executes.

How am I supposed to listen for a specific event and make a bridge call?

Is what I am doing wrong. Please correct me.

Thank you for your support.

Kind regards.
