Hi Razvan,
By agent, I am referring the softphone (zoiper or microsip). I will look
into "Path" or "Mid registar".
I still need to use the rtpproxy module, correct for all of this ?

What does "connect an agent" mean? Register on a specific asterisk
server? If so, you should be using the Path module[1] to add
OpenSIPS as
an extra hop between the agent and Asterisk. An alternative is the Mid
registrar module[2], which can itself store the location of the agent,
and relay calls to it.
