Out of curiosity, what code level in the ISR G2 did you go to when you encountered this? The behavior of simplex streaming is to send a null/fake IP address in the logic channel multimedia control message, which for anything required to check incoming RTP packets
against the IP/port would fail (creating the <i>silent</i> MoH condition) which I was under the impression was only the G3 ISRs.</div>
