Extension Transfer

If you set up 3CX in-house and the internet goes out. Will you still be able to call internally via extension? Someone told me you will not be able too because 3CX has to contact the cloud CA server to work? Thanks in advance.

Hello,

Yes you will still be able to make internal calls normally because the PBX will be locally installed same as the phones.

The issue will only arise if you have external extensions in other places, or use the 3CX clients they won't work since they rely on the internet to reach your PBX, but your local extensions will still work as expected.
