3CX V20 Fake Ring Tone

[Wunan]

Hello Expert Minds

I need your help to resolve the Fake Ring Tone issue every since I upgraded the 3CX to version 20. When an outbound call is made, phone starts to play fake ring tone well before the actual phone starts to ring on the other side. I never had this issue with version 18.

Can someone help me to resolve this issue please.

Thank you in advance.

Is this just one phone?

Custom template?

Can you factory reset it with default template?

Can you factory reset it with default template?

Yes, we are using custom template. Since you told me, I factory rest one phone and re-configured with default template and tried the call. Same results. Immediate Ring Back Tone.
