<tt>Hi, Muhammad!<br>
<br>
The add_path() function should only be called on REGISTER messages,
and it adds a Path header (not a Via). Do you see this header in
your REGISTER message?<br>
For sequential requests, you should use the record_route()
mechanism.<br>
<br>
Best regards,<br></tt>

I am using dispatcher to distribute calls to multiple media
servers, but also want the reply to go through OpenSIPS. So far I
have tried add_path() function which add the Via header but
FreeSWITCH sends the call directly to the gateway not sending the
call back through OpenSIPS. I am not sure if I am doing something
wrong, how can I achieve that?</div>
