Very strange.... Plugged in Huawei 3531 3G LTE dongle as internet standby; all worked well. BUT my VOIP phones de-registered! Unplugged Dongle and phones restored. Is there any thing I can do and is this a recognised problem?

Thanks all, Jeff

    Huaweii 3531 VOIP de-registers. Instant recovery when LTE Dongle removed. Dongle works fine otherwise.

    Hi Jeff, 

    Please check the wireless WAN version on his device. 
    It can be found on Firmware Upgrade page. 
    Please provide the version first. 
    Thank you.
