<tt>Hi Sasmita,<br>
<br>
Not sure if rtpengine has a similar built-in feature (their doc is
something that can be improved :P), but you can achieve the same
from script level I guess (adding and testing that SDP 'a' line).<br>
<br>
Best regards,<br>

If in one leg rtpengine is already involved , </div>
<div>I don,'t want to involved rtpengine again in the other leg
