Re: [asterisk-users] connecting 2 asterisk servers through OpenVPN
There is no problem with the CPU utilization, it is around 40%, I will not be able to try this without the VPN, maybe I should try another VPN solution like OpenSwan, or PPTP. Why do you think that IAX will make a difference than SIP?

Re: [asterisk-users] connecting 2 asterisk servers through OpenVPN
IAX allows trunking. With 16 channels open between 2 asterisk servers that should recover over 400kbs compared to SIP. I believe OpenVPN can be forced into a no-encryption test mode. If you can do that temporarily it is easier to judge the vpn overhead.

[asterisk-users] connecting 2 asterisk servers through OpenVPN
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. Any tips or recommendations on such setup? I am using SIP and G729 between the 2 servers, openVPN using UDP with no compression.

In that case you would see problems even if both endpoints were on a gigabit LAN. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
