    Sensor Dropping RTP traffic

    tweip

      Hi all,

       

      Recently we are down with an issue where our Cisco phone are able to get connected but there's no audio at all. Packet captures show that we are able to see the SIP connection but no RTP packet at all.

      We perform an bypass on the IPS sensor and calls went back to normal. There was no alerts triggered on relation to any IP address from the source or destination IP.

       

      What can i do next as bypassing the whole network doesn't seems feasible for the long run .
