I have unlocked my ZTE F670L router running firmware V9.0.11P1N40 a long time ago. The main reason for unlocking it was to enable bridge mode, which I successfully achieved. Bridge mode works fine, and I can use a normal PPPoE connection without any issues.
However, during this process, I lost my VoIP connection. I re-configured everything exactly the way it was before unlocking the device, but ever since the unlock, the VoIP service has stopped working under Wan VoIP Connection is active.
I have uploaded images of my current configuration for reference and need help getting VoIP working again.
I also know the correct SIP account password. Before unlocking the router, I used the same credentials with both the MicroSIP app for Windows and with a landline phone, and they worked perfectly.
