Capture Egressing Traffic on Comm-Monitor Port

I am working on a Session Border Controller running

Acme Packet: Acme Packet 4600 SCZ9.1.0 Patch 51

Linux: Oracle Linux branches-7/el7-u9

This SBC has Comm-Monitor configured to a pair of OCOM servers. One of these servers has stopped displaying registration and sip traffic from the SBC. I want to verify that the SBC is sending call data through the Comm-Monitor port.

In the SBC CLI, the Show Comm-Monitor command shows that both Comm-Monitors are connected. It also shows that packets are being sent and that there are no recent errors. I would like to verify this with a packet capture or dump showing the traffic egressing from the port.
