Recommended by someone very focussed on data speeds. That's fine, but I also make a lot of voice calls on cloud based phone systems for my home-office work. This router has no SIP ALG function, which is a must for clear call quality for your voice calls. Disabling SIP ALG is possible on even low grade routers so its a mystery why they don't include this. Huawei Customer Support had no solution. I've raised 2 cases and also gone through Huawei NZ to find a solution. Product will need to be replaced. Only good for those who need fast data and are not making calls from their laptop softphone or wifi.
