How secure is LCS Pro?
Linkus Cloud Service Pro is an application-level tunneling service; it only handles SIP data and the custom protocol data of the Linkus and the connected remote SIP endpoints. It does not touch the PBX data, which means no party can access the PBX through the tunneling server.
All transmission between the PBX and the tunneling server is encrypted. And each PBX will have its own encryption key. Even if the tunneling server is brought down by a hacker, there is no way to replace the tunneling service and get original transmission data since the hacker does not know the encryption method.
The tunneling server is secure and has multiple protection measures. Our operation team stands by to handle any emergency in no time.
Furthermore, for the Remote SIP Service, you can customize remote SIP access authorization by extension and apply IP restriction to further secure all the remote SIP access.
