Hi, I am Michael from the
AstLinux Project. A Linux-based Asterisk + Router/VPN distribution.
We've recently included the excellent
WireGuard VPN into
our project and made some tests comparing it with OpenVPN (which we also include).
WireGuard has much faster throughput on the same hardware and lower jitter than OpenVPN.
It is also very lightweight and easy to implement in Linux.
It would be great if Yealink would consider to additionally include Wireguard into their IP phone firmware in the future.
Wireguard is used by professional VPN providers as well.
Here are some OpenVPN/WireGuard comparisons.
For a single phone call (100Kbps) the UDP jitter is the same (but only 16 datagrams in the test)
As the traffic increases, the WireGuard jitter remains much lower than OpenVPN.

PS: If there is any interest, I can also post the exact data for for the test environment.
