I am trying to connect 2 asterisk servers through OpenVPN, the VPN should carry 16 channel, however when active channels reached 4 concurrent channels, the connection became unstable, with a very high latency (around 900ms), the internet bandwidth is 1Mbps on each server, I have upgraded the bandwidth to double it, but still have exactly the same problem.
<br><br>Any tips or recommendations on such setup?<br><br><br>I am using SIP and G729 between the 2 servers, openVPN using UDP with no compression.<br><br>Thanks,<br>O.Youssef<br>
