    Hi everyone,
    I just moved in this area with no phone reception in my apartment.
    Wifi calling seems to be the only option i have now. I tried to contact Optus multiple times to investigate this area but no success.
    Exetel NBN sent me ZTE H268A router. However, i cannot get Wifi calling through this router.
    I have limited knowledge on setting up the router.
    Optus document : https://www.optus.com.au/content/dam/optus/documents/enterprise/pdf/WiFi_Calling_Factsheet.pdf
    Suggested the settings on this router:
    IKEv2 PORT 500 AND PORT 4500 UDP

    Extel router manual:http://exewiki.exetel.com.au/images...Maintenance_Management(EXETEL)-8March2017.pdf

    I have no clue how to input these values to the router so WIFI calling can be activated.
    I need my phone number to be active 24/7 as my parents emergency devices linked to my phone.

    Wifi calling works perfectly fine on my phone at my brothers house using his internet.

    Can someone please guide me on how to set this router up?

    Thanks so much,
  2. lunarlander

    I read through the link you've provided. You don't need to do anything with your router/gateway in terms of setting up any port forward rules. The document calls out those ports needing to be opened (out bound) in situations where you're running over a corporate network. In many corporate networks, the security posture of the network prevents many commonly open ports from being allowed out to the Internet.

    WiFi calling is meant to allow you better coverage in situations where your cell coverage is spotty or non existent. This means no need for any configuration of the WiFi network you're on as it's meant to allow you to use public hot spots and the like. I was able to use WiFi calling to avoid International charges when I was overseas from the US and in Europe. I used a WiFi network where I didn't have any access to the network configuration.

    If you're having problems with WiFi calling and your modem/router is set for standard defaults, then something else is the issue. What you can do is to check to see if your phone can actually use the WiFi network by just browsing something on the Internet while connected to your WiFi network.
