<div dir="ltr">Hello
<div><br>
</div>
<div>I have a problem with some phone numbers at Telenor. Our door
telephone does not reply with an ACK on the 200 OK.</div>
<div>All I found was a weird SDP response with two "connection
information" lines<br>
</div>

<div>To debug, I would like to remove one of the "Connection
Information (c): IN IP4 194.247.61.31", to see if this is what
confuses the door telephone.</div>
<div>But how do I do that?</div>
<div><br>
</div>
<div>I tried with this but nothing happeded<br>
