Yesterday we switched from Comcast to AT&T and then I changed our public IP addresses on our internet router, firewall/firewall rules and “allowed outbound IPs” with our VOIP provider. I didn’t change anything other than the IP, but now I’m getting "The call was rejected by the server for ALL outbound calls. It’s been two days now and I need to get this figured out - I know it’s a simple issue. Can someone contact me? 954-826-6011 feel free to text and willing to pay a one hour assistance fee. I can’t let this stretch more days. Thanks!
on your ucm
make sure the external address is the current static IP and reboot
