PERS (Port Encryption Relay Server)

For example a ITSP currently running the VoIP Service on a server which in US: [login to view URL], the port is 5060, provider want extend the VoIP service to UAE(the country which blocked the VoIP). Provider just need to set up a PERS server and place it in a country which not block the VoIP, such as Japan, US, Germany etc., assuming the PERS server IP is: [login to view URL], port is: 8022. In the PERS configure file, point the PERS to SIP server: [login to view URL]:5060. The UAE users run Softphone or a client which created base on VoIP SDK, choose the transport to "PERS", enter the PERS IP "[login to view URL]" as SIP server IP, enter the PERS port 8022 as SIP server port, then all are done, the users can make and receive VoIP calls via the PERS, between clients and PERS all SIP messages and RTP packetss are encrypted by AES, the PERS relay all packets between clients and SIP server: [login to view URL]
