Hi supreeth, You have mentioned about rtpengine aswellas rrpproxy in open5g documentation .
The same procedure only I have followed for rtpproxy. And one more thing , I have tried installing rtpengine but libraries are based on Ubuntu bionic . But I am using ubuntu xenial. So libraries are not getting installed properly . Did everything worked fine for you when you tried with rtpproxy for this version (5.3.3)?
