<div dir="ltr">Terms Direct RTP or Proxy RTP through your SIP server has nothing to do with your network routers and switches. It basically means if Client A is sending RTP packets to the IP address of Client B or if Client A is sending RTP packets to the IP address of your SIP server and the SIP server needs to re-send the packets to Client B and vise versa.<div>
<br></div><div>So if the SIP server is in the middle of RTP communications that's proxy RTP. If RTP packets don't reach your SIP server and is only between the Clients, that's Direct speech path.</div><div><br>

<br></div><div>Now when the SIP session established (SIP Packets have to

what is the RTP packets path between the clients to reach their destinations ?<br></div><div>Is
the RTP packets have to pass through Routers and switch to reach its
