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.
