ok, if anyone needs it.. I found the fix for the wifi calling force close issue. well a workaround anyway... there is a tmo wifi calling addon from another rom here (won't post it as I don't want to disrespect and cross post roms)
but I d/l'd that and flash this rom and then flashed that add on and it worked. so I no longer get the force close on the wifi calling.
Hi, your ROM is fantasic. Only a little bug i've find. "Wi-Fi Calling" every time stop work
