    On a trunk with Voip Unlimited, which was working fine yesterday, stopped routing incoming calls. (BT who handle their traffic had a system outage yesterday, and what ever happened in the fix has possibly triggered this issue ?!).

    Anyway for a lot of these clients the following change has restored calls:
    On my Vigor 2820
    Firewall >> General Setup
    Accept large incoming fragmented UDP or ICMP packets ( for some games, ex. CS ) - turn this OFF, hit OK
    I was previously advised to turn this on (maybe by VoipOn?) but it was anyway. I'll need to retest things afterwards.
    Best to reboot as well, and draytek have new firmware out in the last few days that they recommend to install new firmware
