We recently switched out our router to a Fortigate 90E. Ever since then, we've been experiencing intermittent ACK not received issues. I can have 10 calls come in fine and then one drop after 32 seconds and then the next 10 work just fine.
The Fortigate is configured to have a public DNS server as primary and our internal Windows Server DNS as secondary.
When I run wireshark across the interface, I do notice a few TCP retransmission requests.
Any ideas on how I can figure this out?
Thanks!
