OpenVPN server configurations VS number of concurrent calls
I have a challenge for you guys!
The challenge is simple in its definition, which OpenVPN server configurations are required (in terms of CPU and RAM) to achieve which number of concurrent calls (VOIP calls)?
I need to find SIP load test servers online, It should be able to send and receive SIP/RTP
This will be needed for white labeling SIP dialers, and probably hosted services for the same thing.
Any help with this research will be appreciated :-)
