By default, VigorIPPBX 2820 does not allow registration of extensions from WAN or VPN
due to security consideration. You may find this option from the IP PBX >> PBX System
>> SIP Proxy Setting page.
Note: The network security will be higher for the extension registered from VPN.
However, if it is required, please untick the Disable registration from WAN option then
register the extension via VPN tunnel for higher security.
You can achieve the following requests:
Disable registration from WAN and VPN for all extensions.
Enable registration from WAN and VPN for all extensions.
Enable registration from WAN and VPN for some extensions; disable it for all the
other extensions.
Enable registration from WAN for an extension; disable registration from VPN for the
same extension.
Enable registration from VPN for an extension; disable registration from WAN for the
same extension.
