Every now and then I experience audio choppy issue during my call.
It happens randomly with both outgoing & incoming calls.
Network utilization at the time of the incident is only at 2-3Mbps out of 50Mbps capability.
I observe these Warning and Notice in from the asterisk log.

These messages is appearing periodically.
I am running pings to the VoIP trunk’s IP at the same time on the same FreePBX server and there is no abnormal ping delay. They are all within <17ms.
I tried reboot the FreePBX server, disable all other un-use trunks. But the issue is still persisting.
Does anyone have any clue of what is going on?
Thank you.
