<p>Hello,</p>
<p>first thing to look at is the port range. There are some
parameter that you can provide to rtpproxy in command line in
order to increase the range of port it can use -- see 'rtpproxy
-h' or 'man rtpproxy'.</p>
<p>Cheers,<br>

<div>Dear Daniel:<br>

I used a single RTPProxy instance. RTPProxy version = 20040107.
And yes there was traffic for all calls but traffic is one-way.
One leg sends the call and the other just receives it.<br>

<p>Hello,</p>
<p>have you used a single rtpproxy instance? Was there RTP
traffic for all 1900 calls? Is this with rtpproxy 1.2 or
2.0?</p>
