WiFi calling not working with c7800

We have really poor cell service in our house (Verizon) so we rely on wifi calling, especially since I work from home. We got a c7800 modem/router to help with our internet speeds and reliability, but...

    Update: my Wi-Fi calling stopped working again after about an hour, but started working on my husband's phone. Seemed like only one phone would work at a time. I ended up changing the channel on the router and BAM it's working on all phones now. Guess the channel may have been overloaded. So, if anyone else is having this problem, try Disabling SIP ALG and changing the channel on the router.

I have an iPhone 8 and my husband has an iPhone X. Both worked with WiFi calling before we got this new modem/router last week. We were using a Motorola MG7540 previously.

      Are you using any parental controls, disney circe, armor? 

      Or Qos? If so, try them disabled. 

      Also, try connecting the phones to the 5ghz channels and not 2.4ghz.

        No parental controls, and I've tried both the 2.4 and 5g network. Neither enable the wifi calling.
