<tt>Hello </tt>Kchitiz,<br>
<br>
If only called party or both are sending media is up the end-devices
implementation - from SIP and SDP point of view there is no
difference - both end points have the SDP of the other party, so
both of them are able to send and receive RTP (if they want). But be
careful of the sendonly / recvonly indications in SDP.<br>
<br>
From OpenSIPS + Media relay point of view there is no difference, it
should work with a default NAT traversal script.<br>

<div style="">We are planning to have OpenSIPS working as a

<div style="">We have a requirement of early media which is a
bit different from general or usual early media concept. In my
case, the calling party and called party need to have a media
path before the final answer for following:</div>
<div style="">1. Calling party should be able to send video
stream and called party should be able to receive the same
before the called party send a final response(2XX) for the
INVITE (Lets say after 183)</div>
<div style="">2. Both the parties should be able to send and
receive audio streams.</div>
<div style=""><br>
</div>
<div style="">This is different from general early media used in
IVR like system where only called party sends audio stream to
calling party.</div>
<div style=""><br>
</div>
<div style="">Is it possible to have this feature when OpenSIPS
is acting as a proxy in between and doing things like NAT
traversal? Does OpenSIPS require any special
configuration/change to achieve this?</div>
