Title: VoIP cuts out on VLAN (Skype, Teams etc) intermittently
Post by: paul_a2 on October 03, 2020, 11:20:02 am

Hi,

I have setup an own vlan for workstation that is run over same physical port as my regular lan (lan untagged, vlan 10) and everything works fine except that VoIP services cut out randomly for random periods: usually it is once-twice per 30 minute around 5-10 seconds break. In Firewall settings-> Advanced I enabled "Reset all states when a dynamic IP address changes." which made the breaks shorter. To me it looks like some buffer/rulespace or similar would run out and be reset, but I have not been able to find anything in any logs.

I have openvpn client enabled on fw, but I dont think that affects - since after moving workstations to lan (no vlan tagging) it works fine. I also moved mobile to network with vlan tagging, and started experiencing there also cutouts on VoIP.  IPS etc is disabled, Intel I210 nics but all default accelerations are enabled.

Any tips on what to examine / setup to capture issue? I downgraded to 20.1 version and had same issues also on that so not related to new version of Hardened BSD.

Did you ever find a way to fix this? I have the exact same issue and it's pretty annoying. Voice calls audio and video just randomly cuts out but the connection to the internet is maintained the whole time.
