OpenVPN Connection Issue

[Amphibian]

Hey Team,

I did the download/install of OpenVpn Server on the same server as Elastix. I then installed the client portions on several andriod phones, several andriod tablets and one Win 95 desktop.

Issue: once I do a OpenVPN Client "connect" on any device, the device will connect without issue, then I do a sip softphone connection without issue. The problem is that when I go to make a call on any of the softphones after it registers thru the OpenVPN to the Elastix server I have no audio/video in either direction at first. I have to hang the call up then I make the same call again and all works great including audio from that point on unless my OpenVPN disconnects then reconnects and then I have to go thru the same process over again. Frustrating to start a VPN session, register a phone, dial a number, then having to hang up and dial the number right back in order to get phones audio/video working thru VPN. If I register the softphones (andriods or Win) without using the OpenVPN I do not have this audio/video passing issue. Appears to be an issue with the VPN passing the audio/video on first connect.

Any suggestions on what to look for or what might be causing the problem as I am at my witts end trying to correct it.


Thanks,

amphibian

Did you add the vpn network segment as local network in the sip configuration(also check your nat settings)?
Did you allow in your firewall the vpn network segment to allow traffic?

The description sounds like a NAT & Network issue. probably you need to take a look on the sip debug and make a tcpdump capture.

did you port forward the port 5060 for sip
and 10000 -20000 for rtp in your router?
