Can anyone help with inbounds and call transfers dropping or not connecting - I been searching, troubleshooting, Cname, shaken/Stir, and registered my numbers with each of the big mobile networks. I have twilio number but sometimes call transfers work but when I call it immediately drops. I’m m thinking it’s a network possibly SIP thing but I only know a little about this. Any ideas? The closet is using ATT mobile to forward to my Twilio number
