Hello, We have an external user whose 3CX comes up as empty. This issue began this morning when the user logged onto her computer. I have checked her settings under "Configure Account" and everything is correct. We have made sure that the tunnel is enabled in her softphone as well. I did notice on our 3cx server that the SIP register request was blocked on her IP due to WAN requests being blocked. I disabled that option on her extension but the issue has continued. I uninstalled 3cx, restarted the computer with her, reinstalled and re-configured via a new welcome email, without any luck. We also tried with her anti-virus/firewall disabled, and I reset the 3cx password in her client as well just in case. With the block WAN requests being disabled, I no longer see any activity for her extension in the error logs or in the activity logs. Any ideas on what may be causing this and what we can do to correct it?
