      Trying out VIOP phones that use Twilio for a carrier. All works fine...good call quality but there is a 8-10 second incoming ring delay. If I remove Pfsense and use an old Asus router, no issue. I have tried the suggestions from the Pfsense manual like putting firewall optimizations to conservative but the incoming ring delays persist.

      Suggestions?

        Do you see any blocked traffic?

        Is it only the ring that is delayed? The call audio is OK?

        The only thing I can imagine failing like that would be if it's trying one connection type, failing and then falling back to something else.

          @stephenw10 Call quality is fine. I’ll have a look at the logs. Thanks!
