Configuring Wifi Calling on Sonicwall TZ300

My company is currently using a TZ300 Sonicwall with firmware 6.5.4.13. We are having trouble using wifi calling on both Android and iPhone. All the solutions I have found seem to relate to firmware 7.x, which is not available on the TZ300.
Can anyone provide any insight on how to accomplish this?
Also, I saw thas Sonicwall will end support for the TZ300 in January 2025. Given this, I am planning to upgrade. However, I would still like to resolve the issue. Also, I would like to have this thread so there is a solution available to others with the same problem.

@Jhamaker did you checked with Packet Monitor what is getting dropped when trying to do Wifi Calls? Did you allowed the needed traffic from your WLAN Zone to WAN?
This is a recent thread which might give you some insights:
At the end of the day you need to open up UDP 500 and 4500 to the ePDG for the mobile carriers in use. I would know allow VPN in general if not needed.
