That is the address of the next hop and typically a proxy doesn't
use websocket connection to another proxy. Can you show a diagram
with the sip server nodes in your network and what protocols are
used between them?<br>
<br>
Are you simply use record_route() function, or some other function
or different parameters to it?<br>
<br>

I finally managed to place a call from sipml5

rings, and when I answer it sends 200 OK to the
