Clear Local PBX IP in cloud PBX

[Voipuser07]

Version: 16.0.4.504

Is there any option in the PBX not to advertise Local PBX IP to the softphones?
I have a Windows Server in the cloud, physical phones connect via SBC - works flawlessly.

Local PBX IP shows up in the 3CX software client ( Windows, Mac, IOS, Android) and often registration takes a long time and sometimes it times out. I think the phone tries to find the local PBX first and external PBX IP/ fqdn later.

Found the manual way of doing this. Go to the extension > Phone provisioning > Select 3CX app under "Your Phones" and select FQDN under Network.
