Are you writing a Dialer or an IVR?  A Dialer doesn't really need to answer calls.  You can always have one program (or thread) with an inbound socket and another with an outbound socket.

I was considering this approach, however I don't know how to detect and answer a call in "socket inboud" esl mode.

I handle all ESL communications from just one thread which receives and processes or generates all events and commands.  I do have a timer for each call which I use for certain timeouts (user inputs and ring time).

Ok, I will try this approach. Am I right, that in order to handle oubound calls similiar to inbound, I will have to spawn new thread for each call?

I have a Dialer that uses ESL from C, but I make an inbound connection to Freeswitch.  It is a socket which I keep open permanently.

I recommend reading chapter 4 of the FreeSwitch Cookbook.

Hello,

I'm trying to switch from dialogic api to freeswitch/esl. Dealing with inbound calls is easy (using esl outbound socket), however i have some problems with outbound calls.

My application is written in C. I create a handle to esl (esl_connect), then issue "bgapi originate ... &socket(127.0.0.1:8084 async full)" in order to handle this connection just like inbound call. So far so good.

Here come the problems:

1. esl creates new thread for my call - thats ok, it was expected - but I do not receive any events on this new handle...

2. esl_events fails - here is some strace output:

[pid 31588] send(5, "filter unique-id a88f1268-2c28-11e3-befa-311d1641c437\n\n", 55, 0) = 55
[pid 31588] recv(5, "Content-Type: command/reply\nReply-Text: +OK filter added. [unique-id]=[a88f1268-2c28-11e3-befa-311d1641c437]\n\n", 65535, 0) = 110
[pid 31588] send(5, "event plain ALL\n\n", 17, 0) = 17
[pid 31588] recv(5, "Content-Type: command/reply\nReply-Text: -ERR command not found\n\n", 65535, 0) = 64
[pid 31588] send(5, "linger", 6, 0)     = 6
[pid 31588] send(5, "\n\n", 2, 0)       = 2
[pid 31588] recv(5, "Content-Type: command/reply\nReply-Text: -ERR command not found\n\n", 65535, 0) = 64

3. how can i distinguish, whether this call is successfull or not?

What am I doing wrong?
