<div dir="ltr">Hello,<div><br></div><div>I'm working with opensips with heavy CPS, recently I added mediaproxy-dispatcher on the server and couple of relays on different servers in different Data Center. Everything worked fine until we observed that opensips SIP UDP port 5060 got huge queued packets. </div>
<div><br></div><div>That obviously impacts the call processing. I want to know if this is a usual behavior? or can this be treated/tuned ? </div><div><br></div><div>Thanks,</div><div>Sammy</div>
