No. Only S-Series VoIP PBX and K2 Large Capacity IP-PBX need Linkus Cloud Service, and it does not make your PBX a Cloud PBX.
How secure is Linkus Cloud Service?
Linkus Cloud Service is an application-level tunneling service; it only handles SIP data and the custom protocol data of Linkus and 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.
