external USB NIC. If the Pi is receiving too much data, it’ll drop packets. This would appear as an RTP problem even if there isn’t one since RTP packets would be lost. Also consider the packets per second that the Pi CPU can interrupt for. 20ms = 50pps<o:p></o:p></span></p>

<p class="MsoNormal">Mark, what type of device are you using as the sensor?<br>
<br>
I've been looking for a raspberry pi with two Ethernet interfaces but I can't seem to find one.<br>
<br>
I'm assuming we need on port for port mirror traffic and one for internet access to send the data back to voipmonitor.<br>
<br>
<br>
<br>
Thanks,<br>
