Are they running on two separate physical servers? or are you running the opensips server on the same machine?<div>If they are on separate servers, what's your network connectivity? do you have proper port mirroring setup? without port mirroring, you will not be able to see any traffic unless you find a hub instead of a switch - most hubs are actually switches and they send the traffic the one port only. </div>
<div>You need to first fix you network setup and examine it with ngrep or tcpdump and then run opensips on that port. What's the ngrep command you are running?</div><div><br></div><div>Regards,</div><div>Ali</div><div>

if you uncomment the port, it will listen to the default port which is 5060. You can never have opensips to listen to all ports. You always need to listen to a port number. You can bind it to multiple ip addresses though.<div>
<br></div><div>You need to know what port the other sip server is using and configure the same port. Are you doing port mirroring? Use tcpdump command see if the traffic is coming to the server.</div><div><br></div><div>

<div dir="ltr">I want to make my OpenSIPS server listen to another sip server's flow. I uncomment the port=5060 in the opensips.cfg so, the server can listen to all ports but this didn't work and I don't receive any trafic from the other server. In fact I have the IP adress and the port of the other server. How this can be useful??Can any one help, please??</div>
