iPhone Wifi Calling using ASA recent IOS

I am getting one way audio for iPhone Wi-Fi calling.   This started after I used the AnyConnect VPN wizard.  This problem is not over an Anyconnect connection that I am having the issue.  It's within the network connected to a Unifi AP.    I only mentioned the Anyconnect because I used the wizard and I started to get one way audio inside the network going from the inside to outside the network.

Hi,
Are you able to see any udp ports are blocking in ASA for the IP which you are calling.

Its more complicated.  ATT built the architecture for routers that support UPnP.   Cisco ASA doesn't support that.  I am stuck on this one unless someone else has configured their ASA to work with WiFi Calling
