1.
Please uncheck
Disable registration from WAN
from the
IP PBX >> PBX System
>> SIP Proxy Setting
page.
2.
Then open
IP PBX>>Extension
. Click any one of the index numbers.
3.
Now, you will get the following setup page for an extension. Note that the
Allow
Registration from
option has two check boxes, one for
WAN
and the other for
VPN
.
These two options are disabled by default, which means this extension is not allowed
registration from the interface you choose (e.g., WAN, VPN). This is applied to all
extensions by default.
For getting the highest network security, please check
VPN
only.
